                //啟動一個事務。
                SqlTransaction myTran = con.BeginTransaction();
                //為事務建立一個命令，注意我們執行雙條命令，第一次執行當然成功。我們再執行一次，失敗。

SqlBulkCopy還可以從SqlDataReader中獲取資料：

using (SqlConnection sourceConnection =
                   new SqlConnection(connectionString))
        {
            sourceConnection.Open();
            // Get data from the source table as a SqlDataReader.
            SqlCommand commandSourceData = new SqlCommand(
                "SELECT ProductID, Name, " +
                "ProductNumber " +
                "FROM Production.Product;", sourceConnection);
            SqlDataReader reader =
                commandSourceData.ExecuteReader();

            using (SqlConnection destinationConnection =
                       new SqlConnection(connectionString))
            {
                destinationConnection.Open();
                using (SqlBulkCopy bulkCopy =
                           new SqlBulkCopy(destinationConnection))
                {
                    bulkCopy.DestinationTableName =
                        "dbo.BulkCopyDemoMatchingColumns";

                    try
                    {
                        bulkCopy.WriteToServer(reader);
                    }
                    catch (Exception ex)
                    {
                        Console.WriteLine(ex.Message);
                    }
                    finally
                    {
                        reader.Close();
                    }
                }
            }
        }
