DataflowBlock::LinkTo<TOutput> Method (ISourceBlock<TOutput>^, ITargetBlock<TOutput>^, Predicate<TOutput>^)

Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput> using the specified filter.

Namespace: System.Threading.Tasks.Dataflow
Assembly: System.Threading.Tasks.Dataflow (in System.Threading.Tasks.Dataflow.dll)

)

Parameters

source: Type: System.Threading.Tasks.Dataflow::ISourceBlock<TOutput>^
The source from which to link.

target: Type: System.Threading.Tasks.Dataflow::ITargetBlock<TOutput>^
The ITargetBlock<TInput> to which to connect the source.

predicate: Type: System::Predicate<TOutput>^
The filter a message must pass in order for it to propagate from the source to the target.

Return Value

Type: System::IDisposable^

An IDisposable that, upon calling Dispose, will unlink the source from the target.
