What's the easiest way to programmatically check if the current assembly was compiled in Debug or Release mode?

bool isDebugMode = false;
#if DEBUG
isDebugMode = true;
#endif

If you want to program different behavior between debug and release builds you should do it like this:

#if DEBUG
   int[] data = new int[] {1, 2, 3, 4};
#else
   int[] data = GetInputData();
#endif
   int sum = data[0];
   for (int i= 1; i < data.Length; i++)
   {
     sum += data[i];
   }

Or if you want to do certain checks on debug versions of functions you could do it like this:

public int Sum(int[] data)
{
   Debug.Assert(data.Length > 0);
   int sum = data[0];
   for (int i= 1; i < data.Length; i++)
   {
     sum += data[i];
   }
   return sum;
}

The Debug.Assert will not be included in the release build.
