Here is what i use to execute batch files:
proc.StartInfo.FileName = target;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.UseShellExecute = false;
proc.Start();
proc.WaitForExit
(
(timeout <= 0)
? int.MaxValue : timeout * NO_MILLISECONDS_IN_A_SECOND *
NO_SECONDS_IN_A_MINUTE
);
errorMessage = proc.StandardError.ReadToEnd();
proc.WaitForExit();
outputMessage = proc.StandardOutput.ReadToEnd();
proc.WaitForExit();
I don’t know if that will do the trick for you, but I don’t have the problem of it hanging.
