asp.net 使用SqlBulkCopy极速插入数据到 SQL Server

按这个来算,我们那个发水票的时间就会由 10分钟-->20秒,这可太神奇了。 
于是乎,下demo,测试,改成自己一般使用的方法测试,NND,还真可以说是极速。 
在此贴上我的Demo:SqlBulkCopy.rar 

复制代码代码如下:


using System; 
using System.Diagnostics; 
using System.Data; 
using System.Data.SqlClient; 
using Microsoft.ApplicationBlocks.Data; 
namespace ConsoleAppInsertTest 

class Program 

static int count = 1000000; //插入的条数 
static void Main(string[] args) 

long sqlBulkCopyInsertRunTime = SqlBulkCopyInsert(); 
Console.WriteLine(string.Format("使用SqlBulkCopy插入{1}条数据所用的时间是{0}毫秒", sqlBulkCopyInsertRunTime, count)); 
long commonInsertRunTime = CommonInsert(); 
Console.WriteLine(string.Format("普通方式插入{1}条数据所用的时间是{0}毫秒", commonInsertRunTime, count)); 
Console.ReadKey(); 

/// <summary> 
/// 使用普通插入数据 
/// </summary> 
/// <returns></returns> 
private static long CommonInsert() 

Stopwatch stopwatch = new Stopwatch(); 
stopwatch.Start(); 
for (int i = 0; i < count; i++) 

SqlHelper.ExecuteNonQuery(SqlHelper.SqlConnection, CommandType.Text, "insert into passport(PassportKey) values('" + Guid.NewGuid() + "')"); 

stopwatch.Stop(); 
return stopwatch.ElapsedMilliseconds; 

/// <summary> 
/// 使用SqlBulkCopy方式插入数据 
/// </summary> 
/// <returns></returns> 
private static long SqlBulkCopyInsert() 

Stopwatch stopwatch = new Stopwatch(); 
stopwatch.Start(); 
DataTable dataTable = GetTableSchema(); 
for (int i = 0; i < count; i++) 

DataRow dataRow = dataTable.NewRow(); 
dataRow[2] = Guid.NewGuid(); 
dataTable.Rows.Add(dataRow); 

//Console.WriteLine(stopwatch.ElapsedMilliseconds);//初始化数据时间 
SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(SqlHelper.SqlConnection); 
sqlBulkCopy.DestinationTableName = "Passport"; 
if (dataTable != null && dataTable.Rows.Count != 0) 

sqlBulkCopy.WriteToServer(dataTable); 

sqlBulkCopy.Close(); 
stopwatch.Stop(); 
return stopwatch.ElapsedMilliseconds; 

private static DataTable GetTableSchema() 

return SqlHelper.ExecuteDataset(SqlHelper.SqlConnection, CommandType.Text, "select * from Passport where 1=2").Tables[0];
