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。
