.net讓線程支持超時

使用 CancellationTokenSource

復制代碼 代碼如下:

private static void TimeoutTest1()
        {
            var cts = new CancellationTokenSource();

            var thread = new Thread(() =>
            {
                Console.WriteLine(String.Format("線程{0}執行中", Thread.CurrentThread.ManagedThreadId));
                Thread.Sleep(10000);
                Console.WriteLine(String.Format("線程{0}執行中", Thread.CurrentThread.ManagedThreadId));
            });

            cts.Token.Register(() =>
            {
                thread.Abort();
            });
            cts.CancelAfter(1000);

            thread.Start();
            thread.Join();

            Console.WriteLine(String.Format("線程{0}的狀態：{1}", thread.ManagedThreadId, thread.ThreadState));
        }

這里采用了 Abort 終止了線程，CancellationTokenSource 也支持其它模式，可以去官方看看文檔。

使用 Join

復制代碼 代碼如下:

private static void TimeoutTest2()
        {
            var thread = new Thread(() =>
            {
                Console.WriteLine(String.Format("線程{0}執行中", Thread.CurrentThread.ManagedThreadId));
                Thread.Sleep(10000);
                Console.WriteLine(String.Format("線程{0}執行中", Thread.CurrentThread.ManagedThreadId));
            });

            thread.Start();
            thread.Join(1000);
            thread.Abort();

            Console.WriteLine(String.Format("線程{0}的狀態：{1}", thread.ManagedThreadId, thread.ThreadState));
        }

.net讓線程在執行結束后銷毀

線程執行完、遇到未處理異常和被終止后就自動不可用了，如果是垃圾，自然會被 GC 給回收，有一點需要說明的是：線程的未處理異常會導致應用程序的終止，一個線程的異常不會自動冒泡到其它線程。
