C# 鼠标挂钩在处理时会导致鼠标移动抖动

我正在使用UIAutomation构建一个应用程序，它在典型的Microsoft Windows用户界面上标记某些小部件，例如Windows资源管理器、控制面板。我正在使用基于Microsoft博客示例的适当的UIA线程，一切正常。小部件的标签是由某些事件触发的，其中一个事件是使用下面所示的低级mousehook代码单击鼠标。我的问题是，当用户界面在鼠标点击上更新时，当用户界面更新时，鼠标移动会变得抖动（如“不平滑”）。所以我想到的是鼠标操作事件需要在不同的线程中运行。虽然我已经编程好几年了，但它一直处于断断续续的状态，所以对于这种线程问题，我远没有信心。我在鼠标拍卖活动中尝试了下面的代码，但没有任何区别。非常感谢您的帮助。我将特别感谢带有解释的示例代码

所以每次移动鼠标时，你都会更新一个UI并重新运行整个应用程序？为什么？尝试在

MouseHook\u MouseAction（）

的处理程序中使用

this.BeginInvoke（）

在UI上下文中调用方法。不是在每次鼠标移动时，而是在每次鼠标单击时（左或右）因为这是应用程序的本质，它不会返回整个应用程序，而只是更新现有的UI；由于主用户界面不是窗口或窗口控件，而是相同的问题，感谢您的建议。可能不是提出此问题的正确位置，但如果我正在寻找承包商，就此应用程序进行咨询，我该如何做。只是在论坛上做广告？
