Ah well you are right about implicit type conversion... that DOES exist in C#, but its not the same as how it works in PHP AFAIK. I am fairly certain that "0" == 0 in C/C++/C# would always be false, or am I incorrect? 0.0 == 0 in C# DOES return true, for the record, I suppose I forgot about that. Sorry.
