C# List根据某一字段排序 将字段相同的排序到一起

            List<JZJLXQ_Prescription_Item> ciList = new List<JZJLXQ_Prescription_Item>();

            List<JZJLXQ_Prescription_Item> tempItemList = new List<JZJLXQ_Prescription_Item>();

            if (cfxxModel != null && cfxxModel.content != null && cfxxModel.content.prescriptionItems != null)

            {

                foreach (JZJLXQ_Prescription_Item reply in cfxxModel.content.prescriptionItems.list.item)

                {

                    ciList.Add(reply);

                    tempItemList.Add(reply);

                }

            }

            List<JZJLXQ_Prescription_Item> cfItemList = new List<JZJLXQ_Prescription_Item>();

            foreach (JZJLXQ_Prescription_Item cfItem in ciList)

            {

                for (int i = ; i < tempItemList.Count; i++)

                {

                    JZJLXQ_Prescription_Item itemTemp = (JZJLXQ_Prescription_Item)tempItemList[i];

                    if (cfItem.YPZH.Equals(itemTemp.YPZH))

                    {

                        cfItemList.Add(itemTemp);

                        tempItemList.RemoveAt(i);

                        i--;

                    }

                }

            }

           cfItemList 为最终排序结果
