本文转自这篇文章，提供了一种较快的数据插入的思路，转过来做个记录。 

#region 
static void Insert()
{Console.WriteLine("使用Bulk插入的实现方式");Stopwatch sw = new Stopwatch();DataTable dt = GetTableSchema(); using (SqlConnection conn = new SqlConnection(StrConnMsg)){SqlBulkCopy bulkCopy = new SqlBulkCopy(conn);bulkCopy.DestinationTableName = "Product";bulkCopy.BatchSize = dt.Rows.Count;conn.Open();sw.Start();for (int i = 0; i < totalRow;i++ ){DataRow dr = dt.NewRow();dr[0] = Guid.NewGuid();dr[1] = string.Format("商品", i);dr[2] = (decimal)i;dt.Rows.Add(dr);}if (dt != null && dt.Rows.Count != 0){bulkCopy.WriteToServer(dt);sw.Stop();}Console.WriteLine(string.Format("插入{0}条记录共花费{1}毫秒，{2}分钟", totalRow, sw.ElapsedMilliseconds, GetMinute(sw.ElapsedMilliseconds)));}
}
static DataTable GetTableSchema()
{DataTable dt = new DataTable();dt.Columns.AddRange(new DataColumn[] {   new DataColumn("Id",typeof(Guid)),  new DataColumn("Name",typeof(string)),  new DataColumn("Price",typeof(decimal))});return dt;
}
#endregion

运行结果如下： 

插入100w条记录才8s多。打开Sqlserver Profiler跟踪，会发现执行的是如下语句： 

insert bulk Product ([Id] UniqueIdentifier, [NAME] VarChar(50) COLLATE Chinese_PRC_CI_AS, [Price] Decimal(18,2))
