Can run one command via cmd.exe from .NET Windows Form - want to run several

This method below allows me to run ONE dos command in a command prompt and output the result to a textbox.

That is all fine and good, but I don't want to have to exit.  I want to be able to send multiple commands in one session, not one at a time, but still using .NET as I am now.

If I don't run the "exit" command - the proc.ReadStandardOutput.ReadToEnd(  ) stays in a "waiting" state and I never get to see the result of the command in the textBox window.

[DllImport("user32.dll")]
        static extern bool SetForegroundWindow(IntPtr hWnd);

        private void RunGitCommandLine(string command)
        {
            ProcessStartInfo psi = new ProcessStartInfo("cmd");
            psi.UseShellExecute = false;
            psi.RedirectStandardOutput = true;
            psi.CreateNoWindow = true;
            psi.RedirectStandardInput = true;
            var proc = Process.Start(psi);

            proc.StandardInput.WriteLine(@command);
            proc.StandardInput.WriteLine("exit");            
            string s = proc.StandardOutput.ReadToEnd();

            textBoxCommandResult.Text = s;
        }

Open in new window

You can output the log to a text file . . . or multiple text files.

Essentially:

string g = Guid.NewGuid().ToString() +".txt";

//override to append to text file.
  proc.StandardInput.WriteLine(@command + " >> " + g);

Open in new window


Then you can either wait for the file to exist or append multiple outputs to the same file and read it in all at once.

If you're going to wait you might want to spawn this off in another thread.  You can create one huge text files or one text file per command and then combine it on the .net side.
