I made my first Brainfuck program today, which prints the numbers 0-255 and the corresponding character.
I was wondering if I could improve my program, as I'm repeating myself a lot (e.g. 3 x copy & paste "comparer" function):
max == 255
LF == 10
space == 32
'0' == 48
'9' == 57

I think what you need to do instead of check the length of the file is to use a method that is built into PostedFile to check if there is a file to begin with.
if you look on the Microsoft page for PostedFile your code would look more like this
