示例1: ConcurrentExclusiveSchedulerPair
' Create a ConcurrentExclusiveSchedulerPair object.
' Readers will run on the concurrent part of the scheduler pair.
' The writer will run on the exclusive part of the scheduler pair.
Dim taskSchedulerPair = New ConcurrentExclusiveSchedulerPair()
' Create an ActionBlock<int> object for each reader CheckBox object.
' Each ActionBlock<int> object represents an action that can read
' from a resource in parallel to other readers.
' Specifying the concurrent part of the scheduler pair enables the
' reader to run in parallel to other actions that are managed by
' that scheduler.
Dim readerActions = From checkBox In New CheckBox() {checkBox1, checkBox2, checkBox3} _
Select New ActionBlock(Of Integer)(Sub(milliseconds)
' Toggle the check box to the checked state.
' Perform the read action. For demonstration, suspend the current
' thread to simulate a lengthy read operation.
' Toggle the check box to the unchecked state.
toggleCheckBox.Post(checkBox)
Thread.Sleep(milliseconds)
toggleCheckBox.Post(checkBox)
End Sub, New ExecutionDataflowBlockOptions With {.TaskScheduler = taskSchedulerPair.ConcurrentScheduler})
' Create an ActionBlock<int> object for the writer CheckBox object.
' This ActionBlock<int> object represents an action that writes to
' a resource, but cannot run in parallel to readers.
' Specifying the exclusive part of the scheduler pair enables the
' writer to run in exclusively with respect to other actions that are
' managed by the scheduler pair.
Dim writerAction = New ActionBlock(Of Integer)(Sub(milliseconds)
' Toggle the check box to the checked state.
' Perform the write action. For demonstration, suspend the current
' thread to simulate a lengthy write operation.
' Toggle the check box to the unchecked state.
toggleCheckBox.Post(checkBox4)
Thread.Sleep(milliseconds)
toggleCheckBox.Post(checkBox4)
End Sub, New ExecutionDataflowBlockOptions With {.TaskScheduler = taskSchedulerPair.ExclusiveScheduler})
' Link the broadcaster to each reader and writer block.
' The BroadcastBlock<T> class propagates values that it
' receives to all connected targets.
For Each readerAction In readerActions
broadcaster.LinkTo(readerAction)
Next readerAction
broadcaster.LinkTo(writerAction)
