一些LINQ的使用

var list = from staff in staffList

           from extraRecord in extraList

           where staff.staffID == extraRecord.staffID && staff.staffID != Loginer.staffID

           && extraRecord.depOpinion == null

           select extraRecord;

private IList<Model.ExtraInfo> mySort(IList<Model.ExtraInfo> list)

        {

            var tempList = from tp in list orderby tp.applyTime descending select tp;

            IList<TYKY_OA.Model.ExtraInfo> applyList = new List<TYKY_OA.Model.ExtraInfo>();

            foreach (var item in tempList)

            {

                applyList.Add(item);

            }

            return applyList;

        }
