首先抱歉，如果我的英语不好，这是我在这里的第一篇文章，我正在开发C＃Windows窗体应用程序，并且我想检测来自窗体外部的单击（在台式机或其他设备上）。我正在尝试使用MouseKeyHook，因为我认为这是解决我的问题的方法，但是我无法使其工作..这是我的代码（我从https://github.com/gmamaladze/globalmousekeyhook那里获得了它，我也试图将globalevents替换为Hook.AppEvents。任何人都可以帮助我完成这项工作吗？：
private IKeyboardMouseEvents m_GlobalHook;
public void Subscribe()
{
// Note: for the application hook, use the Hook.AppEvents() instead
m_GlobalHook = Hook.GlobalEvents();
m_GlobalHook.MouseDownExt += GlobalHookMouseDownExt;
m_GlobalHook.KeyPress += GlobalHookKeyPress;
}
private void GlobalHookKeyPress(object sender, KeyPressEventArgs e)
{
Console.WriteLine("KeyPress: \t{0}", e.KeyChar);
}
private void GlobalHookMouseDownExt(object sender, MouseEventExtArgs e)
{
Console.WriteLine("MouseDown: \t{0}; \t System Timestamp: \t{1}", e.Button, e.Timestamp);
// uncommenting the following line will suppress the middle mouse button click
// if (e.Buttons == MouseButtons.Middle) { e.Handled = true; }
}
public void Unsubscribe()
{
m_GlobalHook.MouseDownExt -= GlobalHookMouseDownExt;
m_GlobalHook.KeyPress -= GlobalHookKeyPress;
//It is recommened to dispose it
m_GlobalHook.Dispose();
}

我正在使用与程序类型无关的类（winform，WPF等）
举个例子：
using System;
using System.Runtime.InteropServices;
using HookInput.API;
namespace HookInput.Mouse
{
public class MouseInput
{
private const Int32 WM_MOUSEMOVE = 0x0200;
private const Int32 WM_LBUTTONDOWN = 0x0201;

{
if (hooked == on) return;
if (on)
{
mouseHandle = WindowsHookAPI.SetWindowsHookEx(WH_MOUSE_LL, mouseDelegate, IntPtr.Zero, 0);
if (mouseHandle != IntPtr.Zero) hooked = true;
}
else

//mouseData:
//If the message is WM_MOUSEWHEEL, the high-order word of this member is the wheel delta.The low-order word is reserved.

MSLLHOOKSTRUCT lparam = (MSLLHOOKSTRUCT)Marshal.PtrToStructure(lParam, typeof(MSLLHOOKSTRUCT));
int command = (int)wParam;
if (Code < 0 || command == WM_LBUTTONDBLCLK || command == WM_RBUTTONDBLCLK)
return WindowsHookAPI.CallNextHookEx(mouseHandle, Code, wParam, lParam);
if (command == WM_MOUSEMOVE)
{
Console.WriteLine($"x:{lparam.pt.x} y:{lparam.pt.y}");
}
else if (command == WM_LBUTTONDOWN || command == WM_LBUTTONUP)

[StructLayout(LayoutKind.Sequential)]
private struct POINT

文件API：
using System;
using System.Runtime.InteropServices;
namespace HookInput.API
{
public class WindowsHookAPI
{
//public delegate IntPtr HookDelegate(
// Int32 Code, IntPtr wParam, IntPtr lParam);
public delegate IntPtr HookDelegate(Int32 Code, IntPtr wParam, IntPtr lParam);

[DllImport("User32.dll")]
public static extern IntPtr SetWindowsHookEx(Int32 idHook, HookDelegate lpfn, IntPtr hmod, Int32 dwThreadId);
}
}
您可以实例化该类
private MouseInput mouseInputHook = null;
mouseInputHook = new MouseInput();
mouseInputHook.setHook(true); // to activate the mousehook
:
:
mouseInputHook.setHook(false); // to desactivate the mousehook
