示例1: ConcurrentBagDemo
' 导入命名空间
Imports System.Collections.Concurrent
Module ConcurrentBagDemo
' Demonstrates:
' ConcurrentBag<T>.Add()
' ConcurrentBag<T>.IsEmpty
' ConcurrentBag<T>.TryTake()
' ConcurrentBag<T>.TryPeek()
Sub Main()
' Add to ConcurrentBag concurrently
Dim cb As New ConcurrentBag(Of Integer)()
Dim bagAddTasks As New List(Of Task)()
For i = 1 To 500
Dim numberToAdd As Integer = i
bagAddTasks.Add(Task.Run(Sub() cb.Add(numberToAdd)))
Next
' Wait for all tasks to complete
Task.WaitAll(bagAddTasks.ToArray())
' Consume the items in the bag
Dim bagConsumeTasks As New List(Of Task)()
Dim itemsInBag As Integer = 0
While Not cb.IsEmpty
bagConsumeTasks.Add(Task.Run(Sub()
Dim item As Integer
If cb.TryTake(item) Then
Console.WriteLine(item)
itemsInBag = itemsInBag + 1
End If
End Sub))
End While
Task.WaitAll(bagConsumeTasks.ToArray())
Console.WriteLine($"There were {itemsInBag} items in the bag")
' Checks the bag for an item
' The bag should be empty and this should not print anything
Dim unexpectedItem As Integer
If cb.TryPeek(unexpectedItem) Then
Console.WriteLine("Found an item in the bag when it should be empty")
End If
End Sub
End Module
