Remarks

Note

The TPL Dataflow Library (the System.Threading.Tasks.Dataflow namespace) is not distributed with .NET. To install the System.Threading.Tasks.Dataflow namespace in Visual Studio, open your project, choose Manage NuGet Packages from the Project menu, and search online for the System.Threading.Tasks.Dataflow package. Alternatively, to install it using the .NET Core CLI, run dotnet add package System.Threading.Tasks.Dataflow.

Properties

Completion	Gets a Task that represents the asynchronous operation and completion of the dataflow block.
InputCount	Gets the number of input items waiting to be processed by this block.
OutputCount	Gets the number of output items available to be received from this block.

Methods

Complete()	Signals to the IDataflowBlock that it should not accept nor produce any more messages nor consume any more postponed messages.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
LinkTo(ITargetBlock<TOutput>, DataflowLinkOptions)	Links the ISourceBlock<TOutput> to the specified ITargetBlock<TInput> .
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the formatted name of this IDataflowBlock instance.
TryReceive(Predicate<TOutput>, TOutput)	Attempts to synchronously receive an available output item from the IReceivableSourceBlock<TOutput>.
TryReceiveAll(IList<TOutput>)	Attempts to synchronously receive all available items from the IReceivableSourceBlock<TOutput>.

Explicit Interface Implementations

IDataflowBlock.Fault(Exception)	Causes the IDataflowBlock to complete in a Faulted state.
ISourceBlock<TOutput>.ConsumeMessage(DataflowMessageHeader, ITargetBlock<TOutput>, Boolean)	Called by a linked ITargetBlock<TInput> to accept and consume a DataflowMessageHeader previously offered by this ISourceBlock<TOutput>.
