Answer 1

The other answers are correct. Here is some code you could use:

ProcessStartInfo startInfo = new ProcessStartInfo(cmd, args);
startInfo.UseShellExecute = false;
startInfo.RedirectStandardError = true;
Process someProcess = Process.Start(startInfo);
string errors = someProcess.StandardError.ReadToEnd();

Note that if the file is not found you won't get an error on standard error. You will get an exception instead.
