Passing arguments to running process in C#

I've some troubles with running processes and passing args to them. I know how to run process with some args

ProcessStartInfo psi = new ProcessStartInfo("cmd.exe", "/c something");  
Process p = Process.Start(psi)

The problem is that after script is executed process is terminated. That's why there is "/c"

But I'm running multiple scripts and I would like to run them in one process ("cmd.exe") not to start new process every time.

Is there some solutions for it ?

I hope somebody understand what I'm talking about ;)

It sounds like you ought to investigate redirecting the standard input - be sure to also set psi.UseShellExecute to false. You'll probably also want to redirect standard output, so you can have some way of knowing what your child process is doing.

I recommend you utilize a batch file to script the execution of your executables and call your batch file instead. Or, you can do this -

    Process p = new Process();
    ProcessStartInfo info = new ProcessStartInfo();
    info.FileName = "cmd.exe";
    info.RedirectStandardInput = true;
    info.UseShellExecute = false;

    p.StartInfo = info;
    p.Start();

    using (StreamWriter sw = new StreamWriter(p.StandardInput))
    {
        if (sw.BaseStream.CanWrite)
        {
            sw.WriteLine("mysql -u root -p");
            sw.WriteLine("mypassword");
            sw.WriteLine("use mydb;");
        }
    }
