SqlBulkCopy的一个例子

 public bool InsertAll(IList<NewStockLuoPan> list)
         {

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

             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;

                 dt.Rows.Add(dr);
             }
              using (SqlBulkCopy sqlBC=new SqlBulkCopy(connstr))
