How to Execute a Command in C# ?

Command Line argument in c#

//pr1.WaitForExit();//try//{// // create the ProcessStartInfo using "cmd" as the program to be run,// // and "/c " as the parameters.// // Incidentally, /c tells cmd that we want it to execute the command that follows,// // and then exit.// System.Diagnostics.ProcessStartInfo procStartInfo =// new System.Diagnostics.ProcessStartInfo("cmd",commandLine);// // The following commands are needed to redirect the standard output.// // This means that it will be redirected to the Process.StandardOutput StreamReader.// procStartInfo.RedirectStandardOutput = true;// procStartInfo.UseShellExecute = false;// // Do not create the black window.// procStartInfo.CreateNoWindow = true;// // Now we create a process, assign its ProcessStartInfo and start it// System.Diagnostics.Process proc = new System.Diagnostics.Process();// proc.StartInfo = procStartInfo;// proc.Start();// // Get the output into a string// string result = proc.StandardOutput.ReadToEnd();// // Display the command output.// Console.WriteLine(result);//}//catch (Exception ex)//{// MessageBox.Show(ex.Message);
