@denis Not sure.
Actually, yes.
If he has a custom cast operator on Types.
He could have a custom cast operator on Types that takes an object, casts it to a string, and does custom parsing on it.
I wouldn't recommend doing that, but it would work ;)
 
I don't think this is possible
 
It is.
You can create both explicit and implicit cast operators in C#.
 
The problem is that the parameter is object

Q: How do I provide custom cast support for my class?

esacHow do I provide support for casting my class to other types? For example, if I have my own implementation of managing a byte[], and I want to let people cast my class to a byte[], which will just return the private member, how would I do this? Is it common practice to let them also cast this to...

Doesn't matter.
He would be stupid to do that, but it would work.
He could define a cast from object that takes the object and expects a string.
 
The signature should be something similar
public static explicit operator Types(object target)
 
12:17 AM
Yup.
Then he would cast target to a string, which would succeed in that instance.
 
But we cant do that
object is base class
 
Ah, right.
Well, let's see.
I don't see any way that would work.
 
Yep, does that makes the code broken :?
 
Well, I already VTC'ed as unclear, so...
Wait, what if Types derives from string?
 
You cant
 
12:21 AM
String is sealed?
 
Yep
 
I see.
@denis:
var foo = (object)this;
Checkers.GameController.GameController bar = (GameController)foo;
That works.
 
Well everything derives from object doesn't it ..
 
I defined a cast operator from GameController to Checkers.GameController.GameController.
It doesn't complain, so it could work if he had a cast operator from string to Types.
@denis Yeah, I basically forced it to be type object.
It might blow up with a failed cast at runtime, but for a specific subset of usages, it would work. He might just be using within those usages.
So, I would say that code is stupid, but it isn't necessarily broken.
 
Those 2 cases are different
 
12:25 AM
How?
I'm casting from one type to another type through a variable that only knows it is an object.
That's what he's doing too, and he apparently knows the type is string already if his string casts work without blowing up.
 
Can you post a link to your question where this is happening ?
 
So, if he had an object that was really a string, and he cast the object to Types, and he had a custom operator from string to Types, it would work.
I don't have it in a question--I just did it in my IDE.
Although, most of the underlying code (except that cast above) is here: codereview.stackexchange.com/q/150982/34073
 
the only safe part of OP's code is this
Client.Name == (string)valueToSearch || Client.Phone == (string)valueToSearch
If none of those if's evaluate to true the program will crash
if it hasn't already
Where your code kinda needs more context to verify that it will/wont work
 
That's not true.
We know that valueToSearch is a string, if the first one doesn't blow up.
If he has a cast operator from string to Types, this will succeed:
Client.Type == (Types) valueToSearch
 
Hmm
 
12:34 AM
It will implicitly cast it to string for the cast operator.
It doesn't know that it isn't a string, and it won't be a compile error, as I showed above.
I don't like it, but there is a chance that it will work.
Anyway, I have to go eat dinner. Just VTC as unclear, if you want to CV it.
 
Alright I test that out too, will let you know the results, tho it seems like it will work.
@Hosch250 It doesn't work it wont do the cast for you.

yesterday, by Phrancis
What kind of behavior would one expect from push() ing a node to the front of an empty linked list? By that I mean it is only the head pointer
I gave that some thought, and would it make sense that pushing to an empty list just populates the list with its first element?
(and subsequent pushes then work as you'd expect)

Hey @Hosch250 see just above, I saw you responded to it yesterday, do you think that approach would make sense? Since there is nothing to push towards the back of the empty list
 
3:38 AM
@CaptainObvious Looks like someone else's code.
 
@Peilonrayz Good catch, I agree
 
4:01 AM
@Hosch250 Very likely. ;)
 
Blast from the past (an upvote brought me back here)! I rolled back the last revision (sorry for not noticing like, uh, a wee bit earlier), since it basically removed the question from the post; future viewers may be looking for a question with a specific problem similar to their own, to seek answers - and for that the site needs to retain its Q&A nature and not become some discussion forum. If you would like some constructive feedback on this code (or anything that works as intended, really), you can get exactly that and much more on SO's Code Review sister site.

@EBrown beautiful!
 
I'm going to be brutally honest: I'm part of that problem.
 
@EBrown and of the solution
 
@Mat'sMug How so?
 
Solution is to vote... and you can do that ;-)
 
I edited it again.

I don't vote enough, or participate enough for that matter.
 
@Phrancis See what?
 
I mean, you're not alone... I don't even the last time I hit the vote-cap. I should vote more as well. Everybody should.

@EBrown I have 711 votes on cr meta alone.
 
4:45 AM
That's a funny number of rows to me.
@Mat'sMug We all should.
 
8309 on cr main.
@Mat'sMug I hit it just two days ago.
Unless it was three days ago.
Still, not very long ago.
 
If we took the ~10-12 regulars (hell, even the 6-8 users talking in chat every day) and used all 40 votes in a day, that's 240-320 on the low side, and 400-480 on the high side just from the regulars.
That's a lot of votes.
If we used those on the 64 posts coming in daily...
That would be 3.75 to 7.1875 votes on every post hitting the site daily just from the regulars.
 
Only 64 Q+A's coming in each day?
 
@Hosch250 Yeah, that's been the average for the last 30 days.
 
Well, why did I get +11 on my latest question in less than 24 hours?

I'm only talking regulars.
Just people in this room on a daily basis.

Just the regular users in this room that were on the ping list could vote every new post up (or down) to at least 10 at the moment.
That's not even passers-by. Or @Marc-Andre or the other people in the Cardshifter room frequently that still creep around here. :)
That's just people that chat here daily.

@Mat'sMug Not as far as I know.
Just got a 12'th on it.
@EBrown Wait, are you counting off topic posts?
It will be fun to see -16 on some posts.
And if they are deleted, we get our votes back.
 
4:56 AM
@Hosch250 Yes, but usually when those are from -3 to -5 people stop down voting them mostly. So we could probably increase that number much more for on-topic posts.
 
Even though I am one of the top voters, I have almost never used my daily allotment.
 
I personally think that getting more new regulars in here would make a big difference in the long term. I thought that congratulating rep milestones of non-chat-regulars in here (my a mod of course, since only theiy can super-ping) would make a big difference
 
For one, I don't have the time to read that many posts.

@200_success That's the problem I have. I don't have time to read enough around here to keep up with voting.
 
Ditto
 
4:57 AM
For another, I feel that my votes are more meaningful if I discriminate rather than upvote everything that I come across.
And I'm quite picky when voting. If anything in an answer rubs me the wrong way, I end up commenting instead.
 
Yeah, not everything should be +16.
 
@Hosch250 It doesn't have to be. We can use them on existing questions/answers.
I guarantee that there are no people who have voted enough to be able to have voted on even half of the questions + answers on this site. The highest voter is @Jamal at 22k, that's just over half our questions if he only voted on questions, not to mention all the answers as well (66k).
Total vote counts for the top 36 voters (one page) start at 22k, and then go down to 1800.
 
It says that a -4 post is one away from Reversal.
 
5:21 AM
@EBrown Since I was pung, IMO those users are already making a difference, without them we wouldn't have a community.
 
Yeah, I hit the one-vote-short queue and DVLR'ed already.
I've clinched a spot as the number 9 voter for the year, and I didn't vote at all probably half the days.
I have exactly 4 votes per day in the year on average.
I couldn't have planned that better.

@EBrown The part before noon, obviously.
 
Nifty, 00:53 here.
 
It's tomorrow!
Oh wait, it's only today.
Today isn't a good functional variable--it is mutable.
 
@EBrown One more thing is, users who are coming from main SO site(like me) tend to vote less on normal answers as they've seen a lot of such answers. I only vote on answers when I see exceptionally well-written answers.
If you check my stats, I've more helpful flags than votes.
We need to advertise CR on Main Meta, take help from mods/users on Main site to encourage users to join CR.
As we see many questions are migrated from Main to CR, it clearly states that people don't know about CR. Even after migration, the users who posted on these questions don't join CR. These migration should be ideally zero.
 
6:15 AM
@Tushar I'm all for more SO users participating on CR, we need to primarily attract answerers which I feel sure some of the tag regulars there would enjoy if they tried it
 
I'll try to vote more from now.
 
If you see some really good answers on SO (that are recent/active users) feel welcome to comment linking them to appropriate tag searches on CR
 
Sure, I'll.

That's not an awful lot of votes.
The last user on that first page has 42 votes this month. We can do better than that.
That's barely more than a vote a day.
 
if there only were a next question button so that you don't have to navigate back and forth or open new tabs for each, it would go much easier and faster
 
@t3chb0t Right-mouse click + open in new tab.
Close tab when you're done.
Problem solved.
Besides, you're still required to properly read the question/answers before voting.
Don't autovote.
That would kill the system.
 
problem solved, no?
 
@t3chb0t If that isn't good enough, you're trying to shave off seconds where you only got 40 votes a day.
Besides, you're ranked 2nd in the weekly top voters, so you're already doing fairly well.
If you're looking to improve anything, you could throw more flags.
 
I usualy don't flag, I VTC

You can't VTC an answer :-)

The only thing that annoys me about Haskell is it's IDE, I cannot be friends with it
 
@t3chb0t this method is bad private static string GetMemberName(Expression expression) In many cases if it's not possible to specify 2 generic parameters and instead you pass an object boxing will happen which will result in a UnaryExpression not a MemberExpression which will crash the program even if the expression looks fine p => p.X
It should be combined with the GetMemberInfo method I had in the TypeAcessor class (I have it moved to a separate file now)
 
2:29 PM
@t3chb0t oh ... um. you should be aware that . does something completely different from what you expect
 
And in fact I made it as a extension method for Expression, so you can turn your GetMemberName function into a single line =>expression.GetMemberInfo().Member.Name;

@t3chb0t Those methods are really inefficient `PropertyInfo FindProperty<T, TIndex1>`
`SequenceEqual` is a really slow method just by itself.
 
@denis you mean where you can specify several expressions for multiple properties and they are all of type object? now when you say that it makes sense, I remember I once had this problem, I need to bring it back, ideed
 
Yep exactly
The expression will be boxed to an UnaryExpression in that case
 
this doesn't matter, it's going to be executed only once for property access, the expressions and reflection produce much more overhead
 
Are you talking about the FindProperty method ?
 
yes
 
2:45 PM
Oh sorry nvm that I didn't notice it's a private static I thought that it's something that the user can call
 
I guess it would be of no use for him :-] in non-critical parts convenience first
 
Yes I agree

Q: (Java) Consumer/Producer (Concurrency) - Exception Handling

racc44I have a circular buffer (array/first in first out), a consumer and a producer. A producer puts random numbers into the array, and a consumer takes the first number and checks if it is relative prime. My code works, and I think it works correct, but I want to improve it. I am not really shure ab...

 
@denis how about a small combo?
	var memberExpression =
		expression.Body as MemberExpression ??
		(expression.Body as UnaryExpression).Operand as MemberExpression;
	var memberExpression =
		expression.Body as MemberExpression ??
		(expression.Body as UnaryExpression)?.Operand as MemberExpression;
 
This should work too

I'm voting to close this question as off-topic because it contains no specific problem. Questions about reviewing the code may be asked on codereview.stackexchange.com. — Tsyvarev 34 secs ago
 
@denis oh, I just see I have them twice :-] not so pretty
 
3:23 PM
@denis for multiple properties
public class ExpressionList<T> : List<Expression<Func<T, object>>> { }
reader.GetValues(foo, new ExpressionList<Foo>
{
    x => x.Bar
});

Q: entab program which replaces 4 spaces with a tab

SiliproksiI wrote an entab program which needs to replace every \$n\$ spaces with 1 tab. I picked \$n\$ to be 4, so every 4 spaces should be 1 tab. I have a feeling that my code is far too complicated than it should be, and the logic I made it with could be much simpler. The logic of the code: Note: \$n\...

 
@200_success ok, I wasn't sure if this qualifies for a rollback
 
Remember: There's only a few hours left to code, otherwise you'll have to wait until next year
Oh wow I just realized that VS gives the option to add new item from template to add a class (in C# as example), I was using that big interface the whole time and was already thinking there has to be an easier way
 
you're learning c#

Q: Generating a sequence number based on last item of a list

Sirwan AfifiI wrote this method in order to generate a sequence number based on a specific pattern: public string LatestNumber(Guid id = default(Guid)) { var number = ""; if (id == Guid.Empty) { var items = myList.ToList(); var lastNumber = items.Any() ? items[items.Count - 1].Nu...

Yeah, trying to find out where exactly I need to add a JSON file to my WPF application if I want to use it inside
 
@skiwi That's R#.
 
derps around near the Python tag for no reason
 
@Hosch250 Oh, cool
 
@Mast Challenge Accepted.
 
Now what will I do once my free R# subscription ends? :(
 
4:58 PM
Use VSD.
It doesn't replace that nice interface, but it is sure working on replacing the code hints.
And talk to the VS team about making that a little nicer.
 
Wow, Newtonsoft.Json has a few downloads
