以编程方式读取用户定义的项目宏 [英] Read user-defined project macros programmatically

问题描述

如何从 C++ 源代码中读取用户定义的宏(例如 ${SolutionPath})中的 VS 项目环境变量之一?

How can I read one of VS project environment variables oder user-defined macros such as the ${SolutionPath} from source code in C++?

我刚刚创建了一个新的用户定义宏，我想在其中存储项目的当前版本.我想在构建期间使用此值并在 GUI 中显示它.您有什么更好的主意，只在一个地方存储我的产品的当前版本?

I just created a new user-defined macro where I want to store the current Version of my project. I want to use this value during build as well as to show it in the GUI. Do you have any better idea to have only one place to store the current version of my product?

似乎解决方案可能使用/D 为每个项目定义额外的预处理器标志，但我无法使用它来定义带有值的预编译器标志.

It seems like defining additional preprocessor flags for each project using /D might by a solution, but I cannot get it to work to define a precompiler flag with a value.

推荐答案

您可以使用以下格式添加额外的编译器选项

You can add an additional compiler option using the following format

/D "VariableName=\"VariableValue\""

这将使宏在项目中可用，就像您键入一样:

This will make the macro available in the project just as if you typed:

\#define VariableName VariableValue
