查看 ThreadException 文档:

public static void Main(string[] args)
{
   // Add the event handler for handling UI thread exceptions to the event.
    Application.ThreadException += new     
  ThreadExceptionEventHandler(ErrorHandlerForm.Form1_UIThreadException);

  // Set the unhandled exception mode to force all Windows Forms errors
  // to go through our handler.
  Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);

  // Add the event handler for handling non-UI thread exceptions to the event. 
  AppDomain.CurrentDomain.UnhandledException += new       
  UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
}

您可能还希望在调试时不捕获异常，因为这样更易于调试.这有点像黑客，但为此你可以用

You might also want to not catch exceptions when debugging, as this makes it easier to debug. It is somewhat of a hack, but for that you can wrap the above code around with

 if (!AppDomain.CurrentDomain.FriendlyName.EndsWith("vshost.exe")) { ... }

为了防止在调试时捕获异常.

To prevent catching the exceptions when debugging.

编辑:另一种检查在调试器中运行的应用程序的方法，比检查文件名更简洁.

EDIT: An alternate way to check for your application running inside a debugger that feels cleaner than checking a filename.

(见meltform、Kiquenet 和Doug 的评论)

(see comments by moltenform, Kiquenet and Doug)

if(!System.Diagnostics.Debugger.IsAttached) { ... }

这避免了使用与 vshost.exe 不同的调试器的问题.

This avoids the problem of using a different debugger than vshost.exe.
