範例

以下範例示範中止執行緒的做法。 接收執行 ThreadAbortException 緒會使用該 ResetAbort 方法取消中止請求並繼續執行。

using System;
using System.Threading;
using System.Security.Permissions;

public class ThreadWork {
    public static void DoWork() {
        try {
            for(int i=0; i<100; i++) {
                Console.WriteLine("Thread - working.");
                Thread.Sleep(100);
            }
        }
        catch(ThreadAbortException e) {
            Console.WriteLine("Thread - caught ThreadAbortException - resetting.");
            Console.WriteLine("Exception message: {0}", e.Message);
            Thread.ResetAbort();
        }
        Console.WriteLine("Thread - still alive and working.");
        Thread.Sleep(1000);
        Console.WriteLine("Thread - finished working.");
    }
}

class ThreadAbortTest {
    public static void Main() {
        ThreadStart myThreadDelegate = new ThreadStart(ThreadWork.DoWork);
        Thread myThread = new Thread(myThreadDelegate);
        myThread.Start();
        Thread.Sleep(100);
        Console.WriteLine("Main - aborting my thread.");
        myThread.Abort();
        myThread.Join();
        Console.WriteLine("Main ending.");
    }
}

Imports System.Threading
Imports System.Security.Permissions


Public Class ThreadWork
   Public Shared Sub DoWork()
      Try
         Dim i As Integer
         For i = 0 To 99
            Console.WriteLine("Thread - working.")
            Thread.Sleep(100)
         Next i
      Catch e As ThreadAbortException
         Console.WriteLine("Thread - caught ThreadAbortException - resetting.")
         Console.WriteLine("Exception message: {0}", e.Message)
         Thread.ResetAbort()
      End Try
      Console.WriteLine("Thread - still alive and working.")
      Thread.Sleep(1000)
      Console.WriteLine("Thread - finished working.")
   End Sub
End Class


Class ThreadAbortTest
   Public Shared Sub Main()
      Dim myThreadDelegate As New ThreadStart(AddressOf ThreadWork.DoWork)
      Dim myThread As New Thread(myThreadDelegate)
      myThread.Start()
      Thread.Sleep(100)
      Console.WriteLine("Main - aborting my thread.")
      myThread.Abort()
      myThread.Join()
      Console.WriteLine("Main ending.")
   End Sub
End Class

此程式碼會產生下列輸出：

Thread - working.
Main - aborting my thread.
Thread - caught ThreadAbortException - resetting.
Exception message: Thread was being aborted.
Thread - still alive and working.
Thread - finished working.
Main ending.

備註

當呼叫 Abort 該方法以銷毀執行緒時，通用語言執行時會拋 ThreadAbortException 出 .NET Framework 的 。 ThreadAbortException 是一個可以被捕捉的特殊例外，但在區 catch 塊結束時會自動再次被提出。 當此例外被提出時，執行時會執行所有 finally 區塊，然後結束執行緒。 由於執行緒可以在區 finally 塊中進行無界計算或呼叫 Thread.ResetAbort 取消中止，因此無法保證執行緒會終止。 如果你想等中止執行緒結束，可以呼叫該 Thread.Join 方法。 Join 是一個阻塞呼叫，直到執行緒實際停止執行才會回傳。

ThreadAbortException 使用 HRESULT COR_E_THREADABORTED，其值 0x80131530為 。
