Question

How can I rename a directory which has many folders and files underneath it? Directory.Move() keeps throwing errors and I read that you cannot use it on non-empty Directories.

Answer 1

You could always execute the REN command line method:

REN Dir1 Dir2

You could also try:

System.IO.DirectoryInfo di = new System.IO.DirectoryInfo(Server.MapPath("Dir1"));
di.MoveTo(Server.MapPath("Dir2"));

Here is a rough C# version of using the REN method:

        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.UseShellExecute = false;
        startInfo.RedirectStandardInput = true;
        startInfo.RedirectStandardOutput = true;

        startInfo.FileName = "cmd.exe";
        startInfo.WorkingDirectory = "D:\\Temp";
        Process oProcess = Process.Start(startInfo);

        oProcess.StandardInput.WriteLine(@"Echo on");
        oProcess.StandardInput.WriteLine(@"ren ~test2 ~test1");
        oProcess.StandardInput.WriteLine(@"EXIT");
        string output = oProcess.StandardOutput.ReadToEnd();

        oProcess.WaitForExit();

        Console.Write(output);

        oProcess.Close();
