When #if DEBUG runs

Question

I have this code in my C# class.

#if DEBUG
        private const string BASE_URL = \"http://www.a.com/\";
#else
        private const string BASE_URL = \"h         


        

Answer 1

It's a preprocessor directive. The code in the DEBUG part is compiled when you do a debug build (more specifically when the DEBUG constant is defined). I.e. if you do a debug build BASE_URL will point to www.a.com. Otherwise it will point to www.b.com.
