.net让线程支持超时的方法实例和线程在执行结束后销毁的方法

.net让线程支持超时

使用 cancellationtokensource

private static void timeouttest1()
        {
            var cts = new cancellationtokensource();

            var thread = new thread(() =>
            {
                console.writeline(string.format("线程{0}执行中", thread.currentthread.managedthreadid));
                thread.sleep(10000);
                console.writeline(string.format("线程{0}执行中", thread.currentthread.managedthreadid));
            });

            cts.token.register(() =>
            {
                thread.abort();
            });
            cts.cancelafter(1000);

            thread.start();
            thread.join();

            console.writeline(string.format("线程{0}的状态：{1}", thread.managedthreadid, thread.threadstate));
        }

这里采用了 abort 终止了线程，cancellationtokensource 也支持其它模式，可以去官方看看文档。

使用 join

private static void timeouttest2()
        {
            var thread = new thread(() =>
            {
                console.writeline(string.format("线程{0}执行中", thread.currentthread.managedthreadid));
                thread.sleep(10000);
                console.writeline(string.format("线程{0}执行中", thread.currentthread.managedthreadid));
            });

            thread.start();
            thread.join(1000);
            thread.abort();

            console.writeline(string.format("线程{0}的状态：{1}", thread.managedthreadid, thread.threadstate));
        }

.net让线程在执行结束后销毁

线程执行完、遇到未处理异常和被终止后就自动不可用了，如果是垃圾，自然会被 gc 给回收，有一点需要说明的是：线程的未处理异常会导致应用程序的终止，一个线程的异常不会自动冒泡到其它线程。
