asp.net(C#)操作excel（上路篇）

1.作业环境 

开发环境：vs2005 /vs2008
数据库：sql2005

excel:2003

首先

在vs加入com組件(当然也可以加入.net下的excel组件)：

之后vs引用子目录会多出下面三个dll：

 简单操作流程如下：

复制代码代码如下:

using Excel; 

// from bill example 
public void writeExcelAdvance(String outputFile) 
{ 
string[,] myData = 
{ 
{ "车牌号", "类型", "品 牌", "型 号", "颜 色", "附加费证号", "车架号" },
