如何捕获WPF窗口外的MouseUp事件？

题目全在标题里。抱歉，如果是复制品，我真的找不到任何东西。

好吧，非常感谢Anatoliy Nikolaev为我指引了正确的方向！这对我帮助很大，这对于使文章中的代码正常工作非常有用。这就是我现在拥有的：

internal static class MouseHook
{
    private delegate int HookProc(int nCode, int wParam, IntPtr lParam);
    private static int _mouseHookHandle;
    private static HookProc _mouseDelegate;

    private static event MouseUpEventHandler MouseUp;
    public static event MouseUpEventHandler OnMouseUp
    {
        add
        {
            Subscribe();
            MouseUp += value;
        }
        remove
        {
            MouseUp -= value;
            Unsubscribe();
        }
    }

    private static void Unsubscribe()
    {
        if (_mouseHookHandle != 0)
        {
            int result = UnhookWindowsHookEx(_mouseHookHandle);
            _mouseHookHandle = 0;
            _mouseDelegate = null;
            if (result == 0)
            {
                int errorCode = Marshal.GetLastWin32Error();
                throw new Win32Exception(errorCode);
            }
        }
    }

    private static void Subscribe()
    {
        if (_mouseHookHandle == 0)
        {
            _mouseDelegate = MouseHookProc;
            _mouseHookHandle = SetWindowsHookEx(WH_MOUSE_LL,
                _mouseDelegate,
                GetModuleHandle(Process.GetCurrentProcess().MainModule.ModuleName),
                0);
            if (_mouseHookHandle == 0)
            {
                int errorCode = Marshal.GetLastWin32Error();
                throw new Win32Exception(errorCode);
            }
        }
    }

    private static int MouseHookProc(int nCode, int wParam, IntPtr lParam)
    {
        if (nCode >= 0)
        {
            MSLLHOOKSTRUCT mouseHookStruct = (MSLLHOOKSTRUCT)Marshal.PtrToStructure(lParam, typeof(MSLLHOOKSTRUCT));
            if (wParam == WM_LBUTTONUP)
            {
                if (MouseUp != null)
                {
                    MouseUp.Invoke(null, new Point(mouseHookStruct.pt.x, mouseHookStruct.pt.y));
                }
            }
        }
        return CallNextHookEx(_mouseHookHandle, nCode, wParam, lParam);
    }     

    private const int WH_MOUSE_LL = 14;
    private const int WM_LBUTTONUP = 0x0202;

    [StructLayout(LayoutKind.Sequential)]
    private struct POINT
    {
        public int x;
        public int y;
    }

    [StructLayout(LayoutKind.Sequential)]
    private struct MSLLHOOKSTRUCT
    {
        public POINT pt;
        public uint mouseData;
        public uint flags;
        public uint time;
        public IntPtr dwExtraInfo;
    }

    [DllImport("user32.dll", CharSet = CharSet.Auto,
        CallingConvention = CallingConvention.StdCall, SetLastError = true)]
    private static extern int SetWindowsHookEx(int idHook, HookProc lpfn, IntPtr hMod, int dwThreadId);

    [DllImport("user32.dll", CharSet = CharSet.Auto,
       CallingConvention = CallingConvention.StdCall, SetLastError = true)]
    private static extern int UnhookWindowsHookEx(int idHook);

    [DllImport("user32.dll", CharSet = CharSet.Auto,
         CallingConvention = CallingConvention.StdCall)]
    private static extern int CallNextHookEx(int idHook, int nCode, int wParam, IntPtr lParam);

    [DllImport("kernel32.dll")]
    public static extern IntPtr GetModuleHandle(string name); 
}

public delegate void MouseUpEventHandler(object sender, Point p);

使用它非常简单：

MouseHook.OnMouseUp += MouseHookMouseUp;

见此，它指的是

WinForms

，但对于WPF则是相同的。还可以看到这个问题：我实际上没有检查它是否有效，只是看它+1。我会让你知道，这正是我想要的。这很好用，你知道一种方法可以在鼠标点击后取消消息处理，比如说我有一个winform控件，我不想从它还原点击事件，WM_LBUTTONDOWN我捕获消息进程，在某种情况下我希望它停止在那里，控件将不会收到鼠标输入。@eran otzap如果我理解正确，如果您使用的是我回答中的代码，则需要取消订阅：

MouseHook.OnMouseUp-=MouseHookMouseUp

。要停止控件接收鼠标输入，我想，您需要使用一个更“传统”的事件处理程序，比如

control.MouseUp+=control\u MouseUp

，方法应该是这样的：

void control\u MouseUp（object sender，MouseButtonEventArgs e）{e.Handled=true；}

，我使用的是一个wimform组件，它的Z顺序总是更高，并且会出现在mouseup路由事件处理程序之前。有了这些新信息，我可以重新问上面的问题吗？WPF中的Winforms组件？每次我使用Windows窗体主机时，都会因为空域问题而感到痛苦，有些事件根本没有收到。无论如何，你最好问一个单独的问题，如果没有一些代码，我很难理解你需要什么：）
