    The C# preprocessor simply allow you to perform "conditional compiling". Using consts is much more effective than using symbol constants as it usually done in C world.

    you can't use C# preprocessor directive as the ones in C++, you can use it to include or exclude codes from compilation on a certain codition
    example
    #if debug
    // Some code
    #elif release
    //Some other code
    #else
    //some other code
    #endif

    Sadly no... the preprocessor support in C# does not support this kind of value replacement as is supported in C and C++, instead in C# its support is pretty much limited to conditional compilation ala:

    #define MySymbol

    int DoSomething()

    {

    #if MySymbol

    //Is included into build

    return 10;

    #else

    //Is NOT included into build

    return 20;

    #endif

    }
