问题
Is there a way to define the project file path in a solution using a user macro/environment variable? I can't seem to do that.
Kind of like an environment variable is used to define the additional include directories in a C++ project, except I want to do the same for the location of a project file in a solution.
I've tried editing the solution in a text editor to change the path to start with %MyMacroName% or $(MyMacroName) but neither of them seems to parse just right. The project files can't be located when the solution is opened.
回答1:
In .sln file use syntax "%ENV_VAR%rest_of_the_path\test.csproj"
In .csproj file use syntax "$(ENV_VAR)rest_of_the_path\test.dll"
That works for me, ENV_VAR is custom environment variable defined for operating system like ENV_VAR = "C:\MyPath\"

MSBuild allows you use to environment variables,
http://msdn.microsoft.com/en-US/library/ms171459(v=VS.80).aspx
So that you should be able to define environment variables as you wish, and then modify vCxproj files to make use of them.
I am not sure if that tip works for sln files, as sln files are not MSBuild scripts.
