SqlBulkCopy的一个例子

 public bool InsertAll(IList<NewStockLuoPan> list)

         {

             DataTable dt = new DataTable();

             dt.Columns.Add("StockNo",typeof(string));

             dt.Columns.Add("Angel", typeof(int));

             dt.Columns.Add("YesterDayAmountIn", typeof(decimal));

             dt.Columns.Add("TwoDayAmountInTest", typeof(string));

             dt.Columns.Add("YesterDay10AmountIn", typeof(decimal));

             dt.Columns.Add("TenDayAmountInTest", typeof(string));

             dt.Columns.Add("CreatedDate", typeof(DateTime));

             foreach (var item in list)

             {

                 DataRow dr = dt.NewRow();

                 dr["StockNo"] = item.StockNo;

                 dr["Angel"] = item.Angel;

                 dr["YesterDayAmountIn"] = item.YesterDayAmountIn;

                 dr["TwoDayAmountInTest"] = item.TwoDayAmountInTest;

                 dr["YesterDay10AmountIn"] = item.YesterDay10AmountIn;

                 dt.Rows.Add(dr);

             }

              using (SqlBulkCopy sqlBC=new SqlBulkCopy(connstr))

             {

                 sqlBC.WriteToServer(dt);

             }
