示例1: TryTakeDemo
'Imports System.Collections.Concurrent

'Imports System.Threading.Tasks
Class TryTakeDemo
' Demonstrates:
' BlockingCollection<T>.Add()
' BlockingCollection<T>.CompleteAdding()
' BlockingCollection<T>.TryTake()
' BlockingCollection<T>.IsCompleted
Shared Sub BC_TryTake()
' Construct and fill our BlockingCollection
Using bc As New BlockingCollection(Of Integer)()
Dim NUMITEMS As Integer = 10000
For i As Integer = 0 To NUMITEMS - 1
bc.Add(i)
Next
bc.CompleteAdding()
Dim outerSum As Integer = 0
' Delegate for consuming the BlockingCollection and adding up all items
Dim action As Action =
Sub()
Dim localItem As Integer
Dim localSum As Integer = 0
While bc.TryTake(localItem)
localSum += localItem
End While
Interlocked.Add(outerSum, localSum)
End Sub
' Launch three parallel actions to consume the BlockingCollection
Parallel.Invoke(action, action, action)
Console.WriteLine("Sum[0..{0}) = {1}, should be {2}", NUMITEMS, outerSum, ((NUMITEMS * (NUMITEMS - 1)) / 2))
Console.WriteLine("bc.IsCompleted = {0} (should be true)", bc.IsCompleted)
