Question

I need to start the command window with some arguments and run more commands inside.

For example, launch a test.cmd and run mkdir.

I can launch the test.cmd with processstartinfo , but i am not sure how to run further commands. Can I pass further arguments to the test.cmd process?

How do I go about this?

Unable to add comments to answer… SO writing here.

Andrea, This is what I was looking for. However the above code doesnt work for me.

I am launching a test.cmd which is new command environment (like razzle build environment) and I need to run further commands.

psi.FileName = @"c:\test.cmd";
psi.Arguments = @"arg0 arg1 arg2";

psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = true;
psi.CreateNoWindow = true;
psi.UseShellExecute = false;

Process p = new Process();
p.StartInfo = psi;
p.Start();
p.StandardInput.WriteLine(@"dir>c:\results.txt");
p.StandardInput.WriteLine(@"dir>c:\results2.txt");

You can send further commands to cmd.exe using the process
standard input. You have to redirect it, in this way:

var startInfo = new ProcessStartInfo
                    {
                        FileName = "cmd.exe",
                        RedirectStandardInput = true,
                        RedirectStandardOutput = true,
                        UseShellExecute = false,
                        CreateNoWindow = true
                    };

var process = new Process {StartInfo = startInfo};

process.Start();
process.StandardInput.WriteLine(@"dir>c:\results.txt");
process.StandardInput.WriteLine(@"dir>c:\results2.txt");
process.StandardInput.WriteLine("exit");

process.WaitForExit();

Remember to write “exit” as your last command, otherwise the cmd process doesn’t terminate correctly…
