由链接 ITargetBlock<TInput> 调用，以释放以前 DataflowMessageHeader 保留的此 ISourceBlock<TOutput>版本。

 virtual void System.Threading.Tasks.Dataflow.ISourceBlock<T>.ReleaseReservation(System::Threading::Tasks::Dataflow::DataflowMessageHeader messageHeader, System::Threading::Tasks::Dataflow::ITargetBlock<T> ^ target) = System::Threading::Tasks::Dataflow::ISourceBlock<T>::ReleaseReservation;
void ISourceBlock<T>.ReleaseReservation(System.Threading.Tasks.Dataflow.DataflowMessageHeader messageHeader, System.Threading.Tasks.Dataflow.ITargetBlock<T> target);
abstract member System.Threading.Tasks.Dataflow.ISourceBlock<T>.ReleaseReservation : System.Threading.Tasks.Dataflow.DataflowMessageHeader * System.Threading.Tasks.Dataflow.ITargetBlock<'T> -> unit
override this.System.Threading.Tasks.Dataflow.ISourceBlock<T>.ReleaseReservation : System.Threading.Tasks.Dataflow.DataflowMessageHeader * System.Threading.Tasks.Dataflow.ITargetBlock<'T> -> unit
Sub ReleaseReservation (messageHeader As DataflowMessageHeader, target As ITargetBlock(Of T)) Implements ISourceBlock(Of T).ReleaseReservation

参数

messageHeader
DataflowMessageHeader

DataflowMessageHeader正在释放的保留消息。

target
ITargetBlock<T>

ITargetBlock<TInput>释放以前保留的消息。

实现

ReleaseReservation(DataflowMessageHeader, ITargetBlock<TOutput>)

例外

ArgumentException

无效 messageHeader 。

ArgumentNullException

target 是 null。

InvalidOperationException

未 target 保留消息。

注解

只有 ITargetBlock<TInput> 链接到此 ISourceBlock<TOutput> 实例的实例可以使用 ReleaseReservation，并且它只能用于释放 DataflowMessageHeader 以前和成功由目标保留的实例。
