asp.net线程批量导入数据时通过ajax获取执行状态

using System.Web.UI.WebControls;

public partial class test : System.Web.UI.Page
{
 protected void Page_Load(object sender, EventArgs e)
 {
  string action = Request.Form["action"];
  if (!string.IsNullOrEmpty(action))
  {
   Hashtable temp = tmethod();
   if (temp == null)
   {
    Thread trd = new Thread(new ParameterizedThreadStart(insertData));
    trd.Start(action);
   }
   else
   {
    if (temp["reCode"].ToString() == "100")
    {
     
     Session.Remove("process");
    }
   }

   JavaScriptSerializer ser = new JavaScriptSerializer();
   String jsonStr = ser.Serialize(temp);
   Response.Write(jsonStr);
   Response.End();
  }
 }


 public Hashtable tmethod()
 {
  return (Hashtable)Session["process"];
 }

 private void insertData(object obj)
 {
  string action = obj.ToString();
  int tCount = 100;
  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！
