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.

DataflowBlockOptions is mutable and can be configured through its properties.

When specific configuration options are not set, the following defaults are used:

Options Default
TaskScheduler Default
MaxMessagesPerTask DataflowBlockOptions.Unbounded (-1)
CancellationToken None
BoundedCapacity DataflowBlockOptions.Unbounded (-1)

Dataflow blocks capture the state of the options at their construction. Subsequent changes to the provided DataflowBlockOptions instance should not affect the behavior of a dataflow block.

Constructors

DataflowBlockOptions()

Initializes a new DataflowBlockOptions.

Fields
