範例

以下程式碼範例說明如何將資訊傳遞給正在中止的執行緒。

using System;
using System.Threading;

class Test
{
    public static void Main()
    {
        Thread newThread  = new Thread(new ThreadStart(TestMethod));
        newThread.Start();
        Thread.Sleep(1000);

        // Abort newThread.
        Console.WriteLine("Main aborting new thread.");
        newThread.Abort("Information from Main.");

        // Wait for the thread to terminate.
        newThread.Join();
        Console.WriteLine("New thread terminated - Main exiting.");
    }

    static void TestMethod()
    {
        try
        {
            while(true)
            {
                Console.WriteLine("New thread running.");
                Thread.Sleep(1000);
            }
        }
        catch(ThreadAbortException abortException)
        {
            Console.WriteLine((string)abortException.ExceptionState);
        }
    }
}

Imports System.Threading

Public Class Test

    <MTAThread> _
    Shared Sub Main()
        Dim newThread As New Thread(AddressOf TestMethod)
        newThread.Start()
        Thread.Sleep(1000)

        ' Abort newThread.
        Console.WriteLine("Main aborting new thread.")
        newThread.Abort("Information from Main.")

        ' Wait for the thread to terminate.
        newThread.Join()
        Console.WriteLine("New thread terminated - Main exiting.")
    End Sub

    Shared Sub TestMethod()
        Try
            While True
                Console.WriteLine("New thread running.")
                Thread.Sleep(1000)
            End While
        Catch abortException As ThreadAbortException
            Console.WriteLine( _
                CType(abortException.ExceptionState, String))
        End Try
    End Sub

End Class
