You have to use the System.Diagnostics.Process class. The following code issues a dir command and retrieves all the output generated by the command prompt in a string variable. You can write its contents to a file if you want:
ProcessStartInfo si = new ProcessStartInfo("cmd.exe"); // Redirect both streams so we can write/read them. si.RedirectStandardInput = true; si.RedirectStandardOutput = true; si.UseShellExecute = false; // Start the procses. Process p = Process.Start(si); // Issue the dir command. p.StandardInput.WriteLine(@"dir c:"); // Exit the application. p.StandardInput.WriteLine(@"exit"); // Read all the output generated from it. string output = p.StandardOutput.ReadToEnd();
