示例1: ServerClass
' 導入命名空間
Imports System.Threading
Public Class ServerClass
Public Shared Sub StaticMethod(obj As Object)
Dim ct AS CancellationToken = CType(obj, CancellationToken)
Console.WriteLine("ServerClass.StaticMethod is running on another thread.")
' Simulate work that can be canceled.
While Not ct.IsCancellationRequested
Thread.SpinWait(50000)
End While
Console.WriteLine("The worker thread has been canceled. Press any key to exit.")
Console.ReadKey(True)
End Sub
End Class
Public Class Simple
Public Shared Sub Main()
' The Simple class controls access to the token source.
Dim cts As New CancellationTokenSource()
Console.WriteLine("Press 'C' to terminate the application..." + vbCrLf)
' Allow the UI thread to capture the token source, so that it
' can issue the cancel command.
Dim t1 As New Thread( Sub()
If Console.ReadKey(true).KeyChar.ToString().ToUpperInvariant() = "C" Then
cts.Cancel()
End If
End Sub)
' ServerClass sees only the token, not the token source.
Dim t2 As New Thread(New ParameterizedThreadStart(AddressOf ServerClass.StaticMethod))
' Start the UI thread.
t1.Start()
' Start the worker thread and pass it the token.
t2.Start(cts.Token)
t2.Join()
cts.Dispose()
End Sub
End Class輸出：
Press 'C' to terminate the application... ServerClass.StaticMethod is running on another thread. The worker thread has been canceled. Press any key to exit.
