Answer 1

This is part of my code using system command taskkill:

//starts a command
public static int RunCommandAndWait(string command, string args)
{
    int result = -1;

    Process p = new Process();
    p.StartInfo.Arguments = args;
    p.StartInfo.CreateNoWindow = true;
    p.StartInfo.FileName = command;
    p.StartInfo.UseShellExecute = true;

    if (p.Start())
    {
        p.WaitForExit();
        result = p.ExitCode;
    }

    p.Dispose();
    return result;
}

//kills a process using its pid and above method
public static void KillProcessTree(int processId)
{
    RunCommandAndWait("taskkill", String.Format("/pid {0} /f /t", processId));
    try
    {
        Process p = Process.GetProcessById(processId);
        if (p != null)
            KillProcessTree(processId); //this sometimes may be needed
    }catch(Exception)
    {

    }
}

You need find window and send message to the window

SendMessage(mbWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);

like have described here

Answer 3

This should do the trick:

// Close process by sending a close message to its main window.
myProcess.CloseMainWindow();
// Free resources associated with process.
myProcess.Close();
