问题
I have several classes in a project which need to only be in certain builds of the application which are currently not ready for release or debug.
To prevent these classes from being used, I want to set around them this:
#if USE_MYCLASS
// Code here...
#endif
Unfortunately, I don't know how to setup a project wide #define.
Is there a functionality in Visual Studio to set project wide definitions.
If there is, though I don't need it right now, is there a functionality to set solution wide definitions?
If there is no functionality for such (seeing as C# does not have include files, I suppose it's possible), is there any method or plugin of doing this functionality without using the command line compiler and /D?
回答1:
You can do that in the project properties, but not in source code.
Project Properties => Build => Conditional compilation symbols
You can specify whichever symbols you need (space delimited, but IIRC is is quite forgiving). Note that DEBUG and TRACE can also be toggled with a checkbox.
I have some projects with multiple "release" build configurations, with different symbols in each (for building 2.0 vs 3.0 vs 3.5 versions - see <DefineConstants> here)
