C# Compiler Directives

Question

I’m looking at some C# code, and have come across the following statement:

#if DEBUG
    // Do something here
#else
    // Do something else
#endif
         


        

Answer 1

It is set with the #define directive or in the compiler settings. It is common for DEBUG to be defined in debug releases, so you could conditionally compile some code like in your example.

You can read more about it on MSDN.
