asp.net 不存在此行/列的数据

Question

还有就是语法问题
            using (OleDbDataReader DataReader_GetData = RsCommand_GetData.ExecuteReader(CommandBehavior.CloseConnection))
            {                if (DataReader_GetData.Read())
                {
                    ...
                }
            }

Answer 1

            OleDbCommand RsCommand_GetData = new OleDbCommand("select top 1 id,title,content from [bin_notes] where [id] =" + Request.QueryString["id"].ToString(), myConn);
             using (OleDbDataReader DataReader_GetData = RsCommand_GetData.ExecuteReader(CommandBehavior.CloseConnection))
            {                if (DataReader_GetData.Read())
                {
                    this.title.Text=DataReader_GetData.GetString(1);//字段顺序一定要写对,0开始
                    this.myEditor.InnerText =DataReader_GetData.GetString(2);
                }
            }
