| AggregateException..::.Handle Method |
| AggregateException Class See Also Send Feedback |
Invokes a handler on each Exception contained by this AggregateException.
Namespace:
System
Assembly:
System.Threading (in System.Threading.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Sub Handle ( _ predicate As Func(Of Exception, Boolean) _ ) |
| C# |
|---|
public void Handle( Func<Exception, bool> predicate ) |
Parameters
- predicate
- Type: System..::.Func<(Of <(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.
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(Func<(Of <(Exception, Boolean>)>)) method simply returns. If any
invocations of the predicate throws an exception, it will halt the processing
of any more exceptions and immediately propagate the thrown exception as-is.
Exceptions
| Exception | Condition |
|---|---|
| System..::.AggregateException | An exception contained by this AggregateException was not handled. |
| System..::.ArgumentNullException | The predicate argument is null. |
