This question is off-topic for many reasons: it's not your own code, there's no code in the question, you're asking for code to be written, and you're not asking for a code review. — 200_success ♦ 17 secs ago

A: Query the context or resulting list

There are a few potential issues here, speed and accuracy in particular. Speed The cache is often faster than querying a value directly because of computation - you need to input, process, calculate, and output values. For example, when you search the web, the servers return results based on c...

A: Kruskal algorithm implementation for adjacency list represented graph

Since Vertex just has public members, it can just be a struct. In addition, you don't need to set bVisited to false in two places. It just needs to be done in the constructor. You could also make it an initializer list instead, which is more proper when setting default values for data members...

01:38

Palmface ^^

Ethan Bierlein

@Mat'sMug Yup. Mostly the same, except for the type declarations, and syntax of dictionary elements.

Dictionary<string, Func<int, int>> d = new Dictionary<string, Func<int, int>>() {
	{"f", (x) => x * x}
};

Console.WriteLine(d["f"](10));

Mat's Mug

    var d = new Dictionary<string, Func<int, int>>()
    {
	{"f", (x) => x * x}
    };

var-ftw

...and braces :)

Ethan Bierlein

You darn kids! Back in my day, we had to be explicit, and we didn't have var!

Mat's Mug

how is (x) => x * x explicit?

delegate(int x) { return x*x; };

:p

Ethan Bierlein

I'm talking about using var over typing out the full type, Dictionary<string, Func<int, int>>

Not about the lambda itself.

Mat's Mug

01:48

yes, and I'm saying if you have anonymous methods and lambdas, you do have var ;-)

Ethan Bierlein

Ah, okay. Thank you master C# guru.

Mat's Mug

lol

Ethan Bierlein

@Mat'sMug Although, I thought that you couldn't do this: var f = (x) => x * x; Am I right?

Mat's Mug

right, because you can't assign a lambda expression to an implicitly-typed variable

Ethan Bierlein

Okay, so why can you use var in place of Dictionary<string, Func<int, int>> then?

Mat's Mug

because the type is right there: new Dictionary<string, Func<int, int>>
