剛進公司時，領導說物流水系統有一個問題：發送水票速度很慢，每發送一次就得等10多分鐘，問我有沒有解決方法，時間原因一直沒去研究。

今天早上reader 上收到cnblogs的訂閱里看到一個關于SQL語句快速插入的文章，提到SqlBulkCopy，感覺不錯，按他的測試SqlBulkCopy要比普通插入快近30倍，

按這個來算，我們那個發水票的時間就會由 10分鐘-->20秒，這可太神奇了。

于是乎，下demo，測試，改成自己一般使用的方法測試，NND，還真可以說是極速。

 在此貼上我的Demo:UploadFiles//SqlBulkCopy.rar

            if (dataTable != null && dataTable.Rows.Count != 0)
            {

            }
            sqlBulkCopy.Close();

            return stopwatch.ElapsedMilliseconds;
        }

        private static DataTable GetTableSchema()
        {
