SetWindowsHookEx 与 WH_MOUSE_LL 会使鼠标减慢几秒钟

Question

我正在使用以下代码来获取当前进程的鼠标消息。

using (Process curProcess = Process.GetCurrentProcess())
using (ProcessModule curModule = curProcess.MainModule)
{
    return SetWindowsHookEx(WH_MOUSE_LL, proc, GetModuleHandle(curModule.ModuleName), 0);
}

由于某种原因，当此代码运行时，鼠标会变慢几秒钟，然后恢复正常。

有任何想法吗？
谢谢

编辑-挂钩方法

private static IntPtr mouseEvent(int nCode, IntPtr wParam, IntPtr lParam)
{
    if (nCode >= 0 && MouseMessages.WM_LBUTTONDOWN == (MouseMessages)wParam)
    {
        MSLLHOOKSTRUCT hookStruct = (MSLLHOOKSTRUCT)Marshal.PtrToStructure(lParam, typeof(MSLLHOOKSTRUCT));     
        LastLeftClick = new ClickInfo { Time = DateTime.Now, X = hookStruct.pt.x, Y = hookStruct.pt.y };
    }
    return CallNextHookEx(hookID, nCode, wParam, lParam);
}

public class ClickInfo
{
    public int X { get; set; }
    public int Y { get; set; }
    public DateTime Time { get; set; }
}

你的钩子程序是什么样的？

如果您的进程只有一个 UI 线程，请改用消息筛选器： http://msdn.microsoft.com/en-us/library/system.windows.forms.application.addmessagefilter.aspx
