【中文标题】MouseKeyHook 应用程序在启动时滞后并且无法关闭

【英文标题】：MouseKeyHook application lags on boot and can't be closed

【问题描述】：

我使用 MouseKeyHook 编写了一个简单的自动点击器。

我使用 MouseKeyHook 的原因是为了检测整个 Windows 操作系统中的全局左键单击。

虽然，当我运行 .exe 时，该软件在单击时出现延迟，一段时间后我似乎无法再点击“X”按钮，并且该应用程序使我的窗口崩溃或减慢了一切速度。

我正在制作这个软件来测试我们的游戏，但这并没有真正的帮助：P

软件代码如下：

using Gma.System.MouseKeyHook;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Runtime.InteropServices;

using System.Threading.Tasks;
using System.Windows.Forms;

namespace Rapid_Fire

        public MOUSEINPUT mi;
    ;

        // Send a left click down followed by a left click up to simulate a full left click
        SendInput(1, ref m_input, Marshal.SizeOf(m_input));
        m_input.mi.dwFlags = MOUSEEVENTF_LEFTUP;
        SendInput(1, ref m_input, Marshal.SizeOf(m_input));

        m_GlobalHook.Dispose();
    

【问题讨论】：

一旦它进入 RapidFire() 然后节目就结束了，你的 UI 线程开始 100% 燃烧并且不会有更多的 UI 事件。所以 m_fire 和 m_close 变量不能改变。永远不要挂起 UI 线程。

所以我要在新线程上运行它？ :)

编写合理的代码是首先要考虑的事情。除了 Random.Next()

Once the q button is hit ... 该消息将永远不会被处理，因为 UI 线程正忙于循环。所有 UI 消息（按键、鼠标点击）都将暂停，直到 RapidFire 完成。您可能想为BackgroundWorker 使用BackgroundWorker 或单独的线程。

用一个新线程修复了它，谢谢大家 :D 由于我没有得到真正的答案，我不能将其标记为好的解决方案 :( 评论不能标记为已解决的答案..

【参考方案1】：

通过另一种方式修复了脚本。原来我必须将它附加到鼠标左键按下事件：D

这里的脚本是：
