最近在写个多线程自动化脚本操作，但是发现会出现线程卡死的现象，因此需要去设置线程超时时间，经过一番研究总结了以下几行代码这里贴出部分来作为记录和参考

/// <summary>
        /// 多个线程
        /// </summary>
        public static void MultipleThreads(int th)
        {

            CountdownEvent latch = new CountdownEvent(th);

            for (int i = 0; i < th; i++)
            {
                try
                {
                    var cts = new CancellationTokenSource();

                    var thread = new Thread(() =>
                     {
                         try
                         {
                             SingleThread();
                         }
                         catch (Exception ex)
                         {

                             Console.WriteLine(ex.Message.ToString());
                         }

                         latch.Signal();
                     });

                    //事件注册
                    cts.Token.Register(() =>
                    {

                        if (thread.ThreadState != System.Threading.ThreadState.Stopped)
                        {
                            try
                            {
                                thread.Abort();
                                BF bf = new BF();
                                ConfigBase.线程超时 = bf.TongJi(ConfigBase.线程超时);
                                latch.Signal();
                                Console.WriteLine("线程超时，已自动kill 掉！");
                            }
                            catch
                            {

                            }
                        }

                    });

                    //设置单个线程最大超时时间
                    cts.CancelAfter(ConfigBase.thread_timeout);
                    thread.Start();
                    Thread.Sleep(2000);
                }
                catch (Exception ex)
                {

                    Console.WriteLine("线程错误，错误原因:{0}",ex.Message.ToString());
                }
            }

            latch.Wait();
            latch.Reset();
            latch.Dispose();
            BsExit();
            Thread.Sleep(3000);

这里说明一下 CountdownEvent latch = new CountdownEvent(th);  是用来等待所有线程执行结束的，其中在线程里面去注册线程超时的时间，var cts = new CancellationTokenSource(); 就是用来注册线程超时的

                    //事件注册
                    cts.Token.Register(() =>
                    {

                        if (thread.ThreadState != System.Threading.ThreadState.Stopped)
                        {
                            try
                            {
                                thread.Abort();
                                Console.WriteLine("线程超时，已自动kill 掉！");
                            }
                            catch
                            {

                            }
                        }

                    });

                    //设置单个线程最大超时时间
                    cts.CancelAfter(1000);
                    thread.Start();
