to capture system-wide keyboard events. But it also allows you to make those keyboard events pass through to other apps. For your particular case, you can define KbHookProc as:

private static int KbHookProc(int nCode, IntPtr wParam, IntPtr lParam)
{
    if (nCode >= 0) // This means we can intercept the event.
    {
        var hookStruct = (KbLLHookStruct)Marshal.PtrToStructure(
                lParam,
                typeof(KbLLHookStruct));

        // Quick check if Ctrl key is down. 
        // See GetKeyState() doco for more info about the flags.
        bool ctrlDown = 
                GetKeyState(VK_LCONTROL) != 0 ||
                GetKeyState(VK_RCONTROL) != 0;

        if (ctrlDown && hookStruct.vkCode == 0x56) // Ctrl+V
        {
            // Replace this with your custom action.
            Clipboard.SetText("Hi");
        }
    }

    // Pass to other keyboard handlers. Makes the Ctrl+V pass through.
    return CallNextHookEx(_hookHandle, nCode, wParam, lParam);
} 

I coded a quick and dirty WinForms app to illustrate this. For the full code listing, see

我要当用户按下Ctrl + V键(无论窗口焦点 - 我的应用程序可能会被最小化)来检测。但我不能停止的实际粘贴操作。

我已经尝试了几件事情:(我成功地绑定到按键与RegisterHotKey)

我有:

 保护覆盖无效的WndProc(参考消息M)
{
如果(m.Msg == 0x312)
热键();
base.WndProc(REF米);
}

和我已经试过如下:

 无效热键()
{
SendKeys.SendWait(“^ v”); //只是把'V',而不是剪贴板内容
}

 无效热键()
{
SendKeys.SendWait(ClipBoard.GetText());
/ *这工作,但由于按Ctrl仍下降,它会触发
*所有应用程序的快捷键,例如如果键盘
*包含'S',然后,而不是把“S”的应用程序,它
*调用Ctrl + S键,这使得应用程序认为用户希望
*进行保存。
* /
}
