AggregateException.Handle Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Invokes a handler on each Exception contained by this AggregateException object.

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

Syntax

'Declaration
Public Sub Handle ( _
    predicate As Func(Of Exception, Boolean) _
)

public void Handle(
    Func<Exception, bool> predicate
)

Parameters

  • predicate
    Type: System.Func<Exception, Boolean>
    The predicate to execute for each exception. The predicate accepts as an argument the Exception to be processed and returns a Boolean to indicate whether the exception was handled.

Exceptions

Exception Condition
ArgumentNullException

The predicate argument is null.
AggregateException

An exception contained by this AggregateException was not handled.

Remarks

Each invocation of the predicate returns true or false to indicate whether the Exception was handled. After all invocations, if any exceptions went unhandled, all unhandled exceptions will be put into a new AggregateException which will be thrown. Otherwise, the Handle method simply returns. If any invocation of the predicate throws an exception, it will halt the processing of any more exceptions and immediately propagate the thrown exception as-is.
