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!
