如何在C#中设置项目范围的#define [英] How to set project wide #define in C#

问题描述

我在一个项目中有几个类，这些类仅需要位于应用程序的某些特定版本中，而这些版本目前尚无法发布或调试.

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.

为了防止使用这些类，我想在它们周围设置这个:

To prevent these classes from being used, I want to set around them this:

#if USE_MYCLASS
// Code here...
#endif

不幸的是，我不知道如何在项目范围内设置#define.

Unfortunately, I don't know how to setup a project-wide #define.

Visual Studio中是否有用于设置项目范围定义的功能?

Is there functionality in Visual Studio to set project-wide definitions?

如果有(尽管我现在不需要)，是否有功能来设置解决方案范围的定义?

If there is, though I don't need it right now, is there a functionality to set solution-wide definitions?

如果没有用于此功能的功能(我想这是可能的，因为C#没有包含文件)，是否有任何方法或插件可以在不使用命令行编译器和/D的情况下执行此功能?

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?

推荐答案

您可以在项目属性中执行此操作，但不能在源代码中执行此操作.

You can do that in the project properties, but not in source code.

项目属性=>构建=>条件编译符号

Project Properties => Build => Conditional compilation symbols

您可以指定所需的任何符号(以空格分隔，但是IIRC相当宽容).请注意，DEBUG和TRACE也可以通过复选框进行切换.

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.

我有一些项目具有多个发布"构建配置，每个配置中都有不同的符号(用于构建2.0、3.0和3.5版本-请参见<DefineConstants>

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)
