个人练习 —— 使用c#、Winform窗体编写鼠标连点器（附代码和工具逻辑）

鼠标连点工具：

工具编写背景：

因在游戏公司工作，游戏运行测试，偶尔需要测试升级或其他操作需要鼠标持续点击，网上下载的连点器广告太多，所以想自己编写了一款鼠标连点工具。

工具需求:

通过命令或操作，使鼠标特定按键持续、有规律的点击屏幕指定位置。

实现原理：

热键相关：

使用Hook（钩子）,监听键盘按下事件。

根据按键获取到按下按键的键值（Keys）。

判断该键值是否为命令热键（快捷键），（是否为开始 | 结束）。

如果是开始，则判断当前工具的状态是否为已开始，如果是，则不执行，否则执行开启连点器功能。

如果是结束，则判断当前工具的状态是否为已开始，如果是，则执行结束命令，否则不执行。

判断该键值是否为紧急结束功能快捷键（ESC键）

为了防止误触，判定需要连续按键4次以上，且每次按键间隔不超过1.5秒。则为有效执行。否则视为无效操作。

鼠标点击相关：

调用了Windows自带的Dll动态连接库 user32.dll 操作鼠标左键的按下、左键抬起，右键按下、右键抬起、移动鼠标等。

使用Timer控件，实现了定时执行点击命令。

其他相关：

使用 Configuration 保存工具配置信息。

具体代码：

钩子相关：
