DispatcherUnhandledExceptionFilterEventArgs.RequestCatch Property

Gets or sets whether the exception should be caught and the event handlers called.

Namespace:  System.Windows.Threading
Assembly:  WindowsBase (in WindowsBase.dll)

public bool RequestCatch { get; set; }

Property Value

Type: System.Boolean
true if the UnhandledException should be raised; otherwise; false. The default value is true.

The UnhandledExceptionFilter event provides a means to not raise the UnhandledException event. The UnhandledException is raised first, and If RequestCatch on the DispatcherUnhandledExceptionFilterEventArgs is set to false, the UnhandledException event will not be raised.

A previous handler in the event multicast might have already set this property to false, indicating that the exception will not be caught. The "don't catch" behavior will override all others because it most likely means a debugging scenario.
