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：


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" },
{ "浙KA3676", "危险品", "货车", "铁风SZG9220YY", "白", "1110708900", "022836" },
