Preprocessor Directives
-
Dirso, Well since .NET only runs in a Windows environment, why would you need to check this...

Hi, First of all, I'm so sorry for asking such a n00b question, but in VC++ 8 I could found the preprocessors directives easily but with C# for VS2008 I have no idea where they are... What directive should I test to be sure the application was compile in Windows?
#if WIN
? Thanks, Dirso
Hi, AFAIK there are no predefined symbols in C#. So if your code includes a
#if WINyou'd better addWINto the "conditional compilation symbols" (in Visual Studio: ProjectProperties/Build) to get it set every time you compile that project. :)Luc Pattyn [Forum Guidelines] [My Articles]

The .NET side of Visual Studio does not define any of the "standard" C++ defines. It does have support for the
#if
preprocessor directive, but you will need to define your own symbols. The only ones that are pre-defined for you, as far as I can remember, are DEBUG and TRACE.

This is from the C# Language Specification[^] The following pre-processing directives are available: • #define and #undef, which are used to define and undefine, respectively, conditional compilation symbols (§2.5.3). • #if, #elif, #else, and #endif, which are used to conditionally skip sections of source code (§2.5.4). • #line, which is used to control line numbers emitted for errors and warnings (§2.5.7). • #error and #warning, which are used to issue errors and warnings, respectively (§2.5.5). • #region and #endregion, which are used to explicitly mark sections of source code (§2.5.6). • #pragma, which is used to specify optional contextual information to the compiler (§2.5.8).

Did you mean this to go to me or the original poster? Good reference on what directives are available, but the question was really about what compilation symbols are defined by default. The OP wanted to know how to write the equivalent of
#if WINin C# (assuming that "WIN" is a predefined conditional symbol in C++), to which the answer is still "there isn't".Scott Dorman

No, not really to the original poster nor directly to you either. I just thought it a good place to inject further information into the thread. I was just following up on the part of your answer that said, "...It does have support for the #if preprocessor directive." I was just adding to the conversation.

No worries, just wasn't sure if this was a "general" post or not. The list of available directives is good, as many people probably don't know about them.

Hi Dirso, I'm not an expert in preprocessor directives (so, this post could be useless), but, thinking that .Net was made only for Windows (MONO was developed after) i've seen one that might help you: #if !MONO #endif I think that this was made on purpose... If you want yo know if you are in MONO, ask for it... Windows is assume. HTH Dirso, Pablo.-

I guess you're right! I'll investigate a little more about MONO and see how it goes. Thanks, Dirso
