UnhandledExceptionEventHandler Delegate

Visual Studio 2010

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

C#
C++
F#
VB
Copy 
[SerializableAttribute]
[ComVisibleAttribute(true)]
public delegate void UnhandledExceptionEventHandler(
	Object sender,
	UnhandledExceptionEventArgs e
)

Parameters

sender
Type: System.Object
The source of the unhandled exception event.
e
Type: System.UnhandledExceptionEventArgs
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.
