未处理的异常

1.控制台应用程序全局捕获未处理的异常

1         static void Main(string[] args)
2         {
3             AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
4         }

2.Winform应用程序全局捕获未处理的异常

 1 public static void Main(string[] args)
 2 {
 3     // Add the event handler for handling UI thread exceptions to the event.
 4     Application.ThreadException += new ThreadExceptionEventHandler(ErrorHandlerForm.Form1_UIThreadException);
 5
 6     // Set the unhandled exception mode to force all Windows Forms errors to go through
 7     // our handler.
 8     Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
 9
10     // Add the event handler for handling non-UI thread exceptions to the event.
11     AppDomain.CurrentDomain.UnhandledException +=
12         new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
13
14     // Runs the application.
15     Application.Run(new ErrorHandlerForm());
16 }

3.WPF应用程序全局捕获未处理的异常

 1     /// <summary>
 2     /// Interaction logic for App.xaml
 3     /// </summary>
 4     public partial class App : Application
 5     {
 6         private void App_OnStartup(object sender, StartupEventArgs e)
 7         {
 8             AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
 9
10             Application.Current.DispatcherUnhandledException += Current_DispatcherUnhandledException;
11         }
12
13         void Current_DispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
14         {
15             throw new NotImplementedException();
16         }
17
18         void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
19         {
20             throw new NotImplementedException();
21         }
22     }

但是AppDomain.CurrentDomain.UnhandledException并非像声明的那样能捕获到所有的异常，详细请参与如下文档。
