Does C# have anything like in C - <br />
<br />
#ifndef BLAH<br />
<br />
#define BLAH<br />
.......<br />
.......<br />
#endif<br />
<br />
in C# I've tried #if (!BLAH) &nbsp;#if (BLAH == false), both of which do not compile.<br />
<br />
Naturally I can just say &nbsp;#if BLAH &nbsp;#else .......... &nbsp;#endif, but I was wondering if C# supported the other. &nbsp;Thanks

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
