从 C# WinForms 应用程序在控制台中的进程完成后暂停？

Question

I'm writing a WinForms application that runs a process in a new console window when a user clicks a button. Is there any way to get the console window to pause - waiting for a keypress - before the process exits, to allow the user to view the output onto the console? The following code runs the process in a console window, but the window disappears immediately after execution finishes:

private void button1_Click(object sender, EventArgs e) {
    Process.Start(@"ffmpeg.exe", "--help");
}

Answer 1

Try using cmd like so (/k makes it not close the window)

private void button1_Click(object sender, EventArgs e) {
    Process.Start(@"cmd.exe", "/k ffmpeg.exe --help");
}

Answer 2

What I had to end up doing was invoking a .bat script that took parameters from the WinForms app to behave how I wanted, and the script finished with a @PAUSE to wait for a keypress. Don't think there's another way to do it, annoyingly.
