Question

我不知道究竟要写什么标题。如果你认为它的标题不正确，我会改变它。这是问题所在。我将下拉列表绑定到数据集（表），我需要字段，如Name，AddressLine1，AddressLine2，City，Email，Country等...我想在标签上显示这些字段（值）。下面是完整的代码：

        public String GetSessionObject()
    {
        string strSession = "";
        if (HttpContext.Current.Session["SessionEmail"] != null)
        {
            strSession = HttpContext.Current.Session["SessionEmail"].ToString();

        }
        return strSession;
    }

    public DataSet BindDropDownListToAUserAddress()
    {

        DataSet ds = new DataSet();
        SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["ConnectionString"]);
        con.Open();
        string strQuery = "SELECT *, FirstName +' '+  LastName as FullName from AUserAddress where AUser_ID = (Select ID from AUser where Email='" + GetSessionObject() + "')";
        SqlCommand cmd = new SqlCommand(strQuery, con);
        using (SqlDataAdapter da = new SqlDataAdapter(cmd))
        da.Fill(ds, "AUserAddress");
        con.Close();
        return ds;
    }


  ddlName.DataSource = objBindDDL.BindDropDownListToAUserAddress().Tables["AUserAddress"];
            ddlName.DataTextField = "FullName";
            ddlName.DataBind();
            lblDisplayAddressLine1.Text = objBindDDL.BindDropDownListToAUserAddress().Tables["AUserAddress"].Columns.("AddressLine1").ToString();-----------????

这是我被困的地方。我需要特定列的值才能使用特定标签。我有什么选择？请指导......

我理解你的问题，因为你可以做到这一点

    // Get User's Details
   DataSet ds=BindDropDownListToAUserAddress();

   // Now from this dataset you can get the specific column like this
   if(ds!=null && ds.Tables.Count>0)
   {
     // I am assuming that your table contains single row of specific user
     string AddressLine1= ds.Tables[0].Rows[0]["AddressLine1"].ToString();
     string AddressLine2= ds.Tables[0].Rows[0]["AddressLine2"].ToString();
   }

指定列到数据集
