Standard error is displaying as ^C after closing the command prompt

C#

Hello,

After executing a command in c#, the command is not closing automatically and also I tried by passing a exit command, but no change.

When I am closing it manually the error message is displaying as "^C"

But the command is working to the requirement but cmd is not closing.


Can any one help what might be the problem.

What I have tried:

ProcessStartInfo start = new ProcessStartInfo();
                start.FileName = @"C:\WINDOWS\system32\cmd.exe";
                start.UseShellExecute = false;
                start.RedirectStandardOutput = true;
                start.RedirectStandardInput = true;
                start.RedirectStandardError = true;
                start.CreateNoWindow = false;
                Process proc1 = new Process();
                proc1.StartInfo = start;
                proc1.Start();
                using (StreamWriter sw = proc1.StandardInput)
                {
                    if (sw.BaseStream.CanWrite)
                    {
                        sw.WriteLine("cd " + "Specified folder");
                        sw.WriteLine(mycommand);
                        sw.WriteLine("exit");
                    }
                }
                    proc1.WaitForExit();
                string outputval = proc1.StandardError.ReadToEnd();
                if (!string.IsNullOrEmpty(outputval))
                    MessageBox.Show(outputval);
