我有以下代码：

    public static void Next()
    {
        Process[] processes = Process.GetProcessesByName("test");

        foreach (Process proc in processes)
            PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_RIGHT, 0);
    }

此代码发送了向右箭头键，我想发送ALT + CTRL + RIGHT，我尝试了以下操作：

    public static void Forward()
    {
        Process[] processes = Process.GetProcessesByName("test");

        foreach (Process proc in processes)
        {
            PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_CONTROL, 0);
            PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_ALT, 0);
            PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_RIGHT, 0);
        }
    }

但这行不通...

有任何想法吗？
