How to check whether 2 DirectoryInfo objects are pointing to the same directory?

Question

I have 2 DirectoryInfo objects and want to check if they are pointing to the same directory. Besides comparing their Fullname, are there any other better ways

Answer 1

You can use Uri objects instead. However, your Uri objects must point to a "file" inside these directories. That file doesn't actually have to exist.

    private void CompareStrings()
    {
        string path1 = @"c:\test\rootpath";
        string path2 = @"C:\TEST\..\TEST\ROOTPATH";
        string path3 = @"C:\TeSt\RoOtPaTh\";

        string file1 = Path.Combine(path1, "log.txt");
        string file2 = Path.Combine(path2, "log.txt");
        string file3 = Path.Combine(path3, "log.txt");

        Uri u1 = new Uri(file1);
        Uri u2 = new Uri(file2);
        Uri u3 = new Uri(file3);

        Trace.WriteLine(string.Format("u1 == u2 ? {0}", u1 == u2));
        Trace.WriteLine(string.Format("u2 == u3 ? {0}", u2 == u3));

    }

This will print out:

u1 == u2 ? True
u2 == u3 ? True
