前言

最近因为工作中遇到一个需求，需要做了一个批量导入功能，但长时间运行没个反馈状态，很容易让人看了心急，产生各种臆想！为了解决心里障碍，写了这么个功能。

通过线程执行导入，并把正在执行的状态存入session，既共享执行状态，通过ajax调用session里的执行状态，从而实现反馈导入状态的功能！

上代码：前端页面

  for (int i = 0; i < tCount; i++)
  {
   Hashtable stateHash = setStateVal(0, i, tCount, action);
   Session["process"] = stateHash; //存入session，方便共享执行状态
   Thread.Sleep(500);
  }
  Session["process"] = setStateVal(100, tCount, tCount, action);
  Thread.CurrentThread.Abort();
 }

 private Hashtable setStateVal(int code, int beingV, int CountV, string action)
 {
  Hashtable stateHash = new Hashtable();
  stateHash["reCode"] = code; //返回状态值
  stateHash["being"] = beingV;  //正在执行值
  stateHash["count"] = CountV;  //总值
  stateHash["action"] = action;  //总值
  return stateHash;
 }
}


ok，共享完毕！
