#if Not Debug in c#?

Question

I have the line in vb code:

#if Not Debug

which I must convert, and I don\'t see it in c#?

Is there something equivalent to it,

Answer 1

     bool isDebugMode = false;
#if DEBUG
     isDebugMode = true;
#endif
    if (isDebugMode == false)
    {
       enter code here
    }
    else
    {
       enter code here
    }
