如何通过 PID 向 CMD 进程发送关闭命令

Question

这个进程是由selenium启动的

所以我无法控制它的启动方式

但是CMD进程有X按钮

我可以通过 PID 编程调用那个 X 按钮吗？

C# 4.6.2 windows8.1

我可以终止该进程，但它的效果与单击 X 按钮的效果不同

Answer 1

您需要找到 window and send message 到 window

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

如描述here

Answer 2

这应该可以解决问题：

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

Answer 3

这是我使用系统命令 taskkill 的部分代码：

//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)
    {

    }
}
