如何將IList轉化爲datatable

 public DataTable IListOut(IList<T> ResList)
        {
            DataTable TempDT = new DataTable();

            //此處遍歷IList的結構並建立同樣的DataTable
            System.Reflection.PropertyInfo[] p = ResList[0].GetType().GetProperties();
            foreach (System.Reflection.PropertyInfo pi in p)
            {
                TempDT.Columns.Add(pi.Name, System.Type.GetType(pi.PropertyType.ToString()));
            }

            for (int i = 0; i < ResList.Count; i++)
            {
                IList TempList = new ArrayList();
                //將IList中的一條記錄寫入ArrayList
                foreach (System.Reflection.PropertyInfo pi in p)
                {
                    object oo = pi.GetValue(ResList[i], null);
                    TempList.Add(oo);
                }

                object[] itm = new object[p.Length];
                //遍歷ArrayList向object[]裏放數據
                for (int j = 0; j < TempList.Count; j++)
                {
                    itm.SetValue(TempList[j], j);
                }
                //將object[]的內容放入DataTable
                TempDT.LoadDataRow(itm, true);
            }
            //返回DataTable
            return TempDT;
        }
