在编译时从C＃获取数据

Question

I've been trying to write C# code that retrieves data from a file in compilation-time, and not in run-time. The thing is that I need to get a version of a file that exists in my machine, but not in machines that would run this DLL. (The version can be changed tomorrow, so I want to able to retrieve that dynamically). In run-time, those machines have no access to the file, and that's why I need to get this data before. Anyone as an idea how to do so ? Thanks.

Answer 1

The C# code that you are compiling will not be run during the compilation.

You should make a pre-build step that extracts the version information. That custom build step could in itself be a C# program if you want. Make that program output a small .cs file containing the version number of the dll and include that .cs file in the source for the main program.

如果要在构建项目之前或之后执行某些操作，可以在项目属性的“ Build Events部分的“ Build Events pre-build event command line或“ post-build command line中编写命令行语句。
