Answer 1

If you append ..\.. to your existing path, the operating system will correctly browse the grand-parent folder.

That should do the job:

System.IO.Path.Combine("C:\\Users\\Masoud\\Documents\\Visual Studio 2008\\Projects\\MyProj\\MyProj\\bin\\Debug", @"..\..");

If you browse that path, you will browse the grand-parent directory.
