 		Is while(x--) in C equal to while(x > 0) in C#?

 		Only if x is positive/unsigned. If x starts at -1, x-- is true (because -2 is true, as it is non-zero). If you can guarantee x is never negative, then yes.

Aside: I can never remember the order in which x-- is done; does it return the decremented value, or the value before it was decremented? In which case, if x is initially 0 it may have a different effect. It's best to be explicit with the conditional you suggested.

 		I ended up porting it (and all other implicit boolean statements) as such:

I don't remember which language this was in, but if I remember correctly... x-- returns the value, THEN decrements it. --x decrements the value, THEN returns it.

 		Well, that's not entirely an accurate conversion.

If x starts at 0,



will not execute, but



WILL execute once.

Convert.ToBoolean on ints isn't really "idiomatic" C#; I'd suggest just going with the following if there's no better looping construct:
