我有一个带有任务栏图标的应用程序.我正在使用notifyicon来完成这项工作. 我已经在安装和卸载该应用程序的Visual Studio中创建了它的安装程序.

I have an application with tray icon. I am using notifyicon to do this job. I have created its setup in Visual Studio which installs and uninstall the application.

问题是当我卸载程序时，它的托盘图标没有被删除，即使卸载了程序，即使从后端删除了其.exe文件，我也可以单击该图标并启动该应用程序.卸载程序.

Problem is when I uninstall the program, its tray icon is not removed and even after the program has been uninstalled, I can click on the icon and start the app even though its .exe file from back end has been deleted by the uninstaller.

推荐答案

通常的方法是在任务栏应用程序中创建一个后台线程，该线程将等待信号通知命名事件.然后，您的卸载程序应将此事件设置为信号状态.信号通知事件后，托盘应用程序即退出.

The usual approach is to create in your tray application a background thread which will wait for a named event to be signaled. Then your uninstaller should set this event into the signaled state. When the event is signaled the tray application just exits.

在任务栏应用程序的后台线程中:

In your tray application's background thread:

EventWaitHandle ev = new EventWaitHandle(false, EventResetMode.AutoReset, "MyCloseEventName");
ev.WaitOne();

在卸载程序中:

EventWaitHandle ev = EventWaitHandle.OpenExisting("MyCloseEventName");
ev.Set();
