你可以使用 AppDomain.UnhandledException 。然而，在您的情况下，您对您的服务的完整呼叫可以包裹在try / catch块中。由于您尚未提供有关此未处理异常的计划的详细信息，因此您认为在这种情况下您正确的路径是让服务崩溃。

You could use AppDomain.UnhandledException. In your case however, your entire call to your service can be wrapped in a try/catch block. Since you haven't provided details for what you plan to do with this unhandled exception, your correct path I think in this case is to let the service crash.

try
{
   MainCallToYourService();
}
catch (Exception)
{
   //it's probably too late to do anything useful here, try to log and die
}

请记住，这样做的问题是，在很多情况下，您的应用程序的状态在此之前被破坏事件提高。最好的办法是尝试登录并退出。

Keep in mind though that the problem in doing this is that in a lot of cases, your application's state is corrupt by the time this event is raised. Your best bet is to try and log it and get out.
