网络线程问题？

Question

如果很多线程同时进行操作，这时候突然断网了，如何在网络连上去的时候线程继续之前的操作？
或者说有什么代码可以记住当前线程的位置，以便还原到断网点！
请大家给个思路？

具体看你连接到网络上作什么事情，比如说你是连接到某个网站上抓取信息的，那么一开始记录下所有要抓取的URL地址，给每个线程分配索引，只有成功抓取的线程索引+1，断网会引发超时异常，线程的索引就不会增加，下个线程启动的时候接着索引继续。                    for (int i = 0; i < checkList.Count; i++)
                    {
                        switch (checkList[i].LoginStatus)
                        {
                            case AccountLoginStatus.ConnectionError:
                            case AccountLoginStatus.NoLogin:
                            case AccountLoginStatus.NeedCode:
                                if (!this.threadRealmDict.ContainsKey(checkList[i]))
                                {
                                    this.threadRealmDict.Add(checkList[i], new List<Thread>());
                                }
                                this.threadRealmDict[checkList[i]].Clear();
                                Thread thread = new Thread(threadStart);
                                thread.Start(checkList[i]);
                                threadList.Add(thread);
                                Thread.Sleep(ConfigManager.AppConfig.Sleep);
                                break;
                        }                        
                    }
