UnhandledExceptionEventHandler Delegate

Represents the method that will handle the event raised by an exception that is not handled by the application domain.

[Visual Basic]
Public Delegate Sub UnhandledExceptionEventHandler( _
   ByVal sender As Object, _
   ByVal e As UnhandledExceptionEventArgs _
public delegate void UnhandledExceptionEventHandler(
   object sender,
   UnhandledExceptionEventArgs e
public __gc __delegate void UnhandledExceptionEventHandler(
   Object* sender,
   UnhandledExceptionEventArgs* e

[JScript] In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters [Visual Basic, C#, C++]

The declaration of your event handler must have the same parameters as the UnhandledExceptionEventHandler delegate declaration.

The source of the unhandled exception event.
An UnhandledExceptionEventArgs that contains the event data.


An UnhandledExceptionEventHandler can only be specified for the default application domain that is created by the system to execute an application. Specifying an UnhandledExceptionEventHandler for an AppDomain created by an application has no effect.

When you create an UnhandledExceptionEventHandler delegate, you identify the method that will handle the event. To associate the event handler with your event, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates.
