  sList = sObj.GetListInfo(condition, "");

            string b = sList[0].Remark.Length > 10 ? sList[0].Remark.ToString().Substring(0, 10) + "..." : sList[0].Remark;

            var result = from a in sList

                         select new

                         {

                             a.ID,

                             a.GoodsName,

                             a.StartTime,

                             a.endTime,

                             a.StartingPrice,

                             a.SuggestPrice,

                             a.AuctionNumber,

                             a.State,

                             Remark = a.Remark.Length > 10 ? a.Remark.ToString().Substring(0, 10) + "..." : a.Remark

                         };

            anp.RecordCount = result.Count();

            this.gv.DataSource = result.Skip((anp.CurrentPageIndex - 1) * anp.PageSize).Take(anp.PageSize);

这句“Remark = a.Remark.Length > 10 ? a.Remark.ToString().Substring(0, 10) + "..." : a.Remark” 有什么问题吗？为什么会报错未实例化对象这个错误，当我把这句改成Remark = a.Remark就不会有错误啦， 当时我调试时那句 string b 没有问题，。。求解
