推荐答案

听起来像你正在使用工具箱中的Timer。这是一个依赖于Events的计时器，以便通知您的应用程序Tick。这也意味着它完全在UI线程（应用程序启动的线程）上运行。当线程每10秒运行一次检查时，它无法执行其他操作，例如更新UI（重新绘制）并响应用户点击。



唯一的解决方案是将检查代码移动到后台线程。这可以通过删除您在表单上删除的Timer而不是使用 System.Threading.Timer [ ^ ]类。它的回调将使用ThreadPool线程来执行您的检查代码。

It sounds like you're using the Timer that's in the Toolbox. This is a timer that depends on Events in order to notify your application of the Tick. This also means it runs entirely on the UI thread (the thread your application started up on). When the thread is running your check every 10 seconds, it can't do other things, like update the UI (repaint it) and respond to user clicks.

The only solution to that is to move your checking code to a background thread. That is easily accomplished by removing the Timer you dropped on the form and instead use the System.Threading.Timer[^] class. It's callback will use a ThreadPool thread to execute your check code.
