——Ilist传值

在线等——Ilist传值
SQLDAL:
private const string SQL_SELECT_JBXX = "select jbxx_xm from TdrSys_jbxx where jbxx_sfzh=@sfzh";

  public IList<TdrSys_jbxx> searchjbxxBySfzh(string sfzh) 
  {
  IList<TdrSys_jbxx> XinXi = new List<TdrSys_jbxx>();
  SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["link"].ConnectionString);
  cn.Open();
  SqlCommand cmd = new SqlCommand(SQL_SELECT_JBXX, cn);
  cmd.Parameters.AddWithValue("@sfzh", sfzh);
  DataTable dt = new DataTable();
  SqlDataAdapter da = new SqlDataAdapter(cmd);
  da.Fill(dt);
  foreach (DataRow myDataRow in dt.Rows)
  {
  var obj = new TdrSys_jbxx();
  XinXi.Add(obj);
  }
  return XinXi;
  }
aspx.cs:
if (!IsPostBack)
  {
  IList<TdrSys_jbxx> list = new List<TdrSys_jbxx>();
  string Num = Session["sfzh"].ToString();
  BTdrSys_jbxx UserID = new BTdrSys_jbxx();
  list = UserID.searchjbxxBySfzh(Num);
  foreach(TdrSys_jbxx xx in list)
  {
  xm.Text += xx.jbxx_xm;
  }
   


  }
为啥xm这个lable得不到值,帮我看看,帮我改一下,感激不尽!
