捕获异常并在崩溃时正确处理程序

Question

AppDomain.CurrentDomain.UnhandledException += 
    new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
Forms.Application.ThreadException += 
    new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);

was the code i snipped off a similar question, but it fails to solve my case. What i'm trying to do is catch a crash and dispose of my application correctly so i don't leave behind memory dumps/traces/systray icons

Answer 1

If you terminate the process using debugger or task manager, there's no way to handle this situation -- be it a .NET application or a native one.

Handling OS exceptions in CLR may be possible, but it is not advised. See Is it possible to catch an access violation exception in .NET? for more details.

In almost all cases, your process should not be terminated in these ways, and even if it does, proper disposing is unnecessary, as OS will properly close almost all handles: files, connections etc. Terminated applications leaving tray icons behind is a 20-year old bug in Explorer and you can't do anything about it. Let's just hope Microsoft will fix it one day.
