Datareader转为DataTable

   System.Data.DataTable dt = new System.Data.DataTable();

                dt.Load(Datareader.DataReader);

                if (dt.Rows.Count > 0)
                {
                    dt.DefaultView.Sort = "IsReCommend desc";

                    Repeater1.DataSource = dt.DefaultView;
                    Repeater1.DataBind();
                    Datareader.Dispose();
                }
