C#//SendKeys.SendWait 仅在进程窗口最小化时起作用

namespace TextSendKeys
{
    class Program
    {
        [DllImport("user32.dll")]
        static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

        static void Main(string[] args)
        {
            Process[] processes = Process.GetProcessesByName("game");
            Process game1 = processes[0];


            IntPtr p = game1.MainWindowHandle;

            ShowWindow(p,1);
            SendKeys.SendWait("{DOWN}");
            Thread.Sleep(1000);
            SendKeys.SendWait("{DOWN}");



        }
    }
}

该程序应该在游戏窗口中发送两次向下按钮。它仅在我的窗口最小化时有效(它正在激活窗口并完成它的工作)。如果我的窗口被激活(不是最小化)，什么也不会发生。如何解决？

谢谢! :)

尝试使用 SetForegroundWindow Win32 API 调用(而不是 ShowWindow)来激活游戏窗口。 (签名来自pinvoke.net。)

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool SetForegroundWindow(IntPtr hWnd);

static void Main(string[] args)
{
    Process[] processes = Process.GetProcessesByName("game");
    Process game1 = processes[0];

    IntPtr p = game1.MainWindowHandle;

    SetForegroundWindow(p);
    SendKeys.SendWait("{DOWN}");
    Thread.Sleep(1000);
    SendKeys.SendWait("{DOWN}");
}
