I have a VS project with an IntermediateDirectory like this: “….\temp\$(SolutionName)\$(ProjectName)”.

I can read this value using a macro or add in, however, I would need the actual directory to manipulate files there. Right now, I manually replace the “$(SolutionName)” and “$(ProjectName)” with the respective values, which works fine but might become complicated when different macros or even user macros from property sheets are used.

So my question is:
Does the Visual Studio API have a built in function to expand macros like these? Or is there some other elegant solution?

    There is an elegant solution! But I only know the one that applies to C++ projects.

    Assuming you’re in a C# add-in:

    // Get the main project from the first startup project

    VCProject vcMainProject = (VCProject)(_applicationObject.Solution.SolutionBuild.StartupProjects as IVCCollection).Item(1);

    Project mainProj = (Project)_vcMainProject .Object;

    // Get the configuration we’ll be using

    IVCCollection cfgs = (IVCCollection)_vcMainProject .Configurations;

    VCConfiguration vcCfg = (VCConfiguration) cfgs.Item(mainProj.ConfigurationManager.ActiveConfiguration.ConfigurationName + “|” + mainProj.ConfigurationManager.ActiveConfiguration.PlatformName);

    string finalString = vcCfg.Evaluate(“….\temp\$(SolutionName)\$(ProjectName)”);

    You can also check out this page:

    If you’re not using this for C++, there should be a similar interface for the Project, Configuration, and Solution classes provided for other languages (C# and VB).
