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：
  1 using Excel;
  2 // from bill example
  3         public void writeExcelAdvance(String outputFile)
  4         {
  5             string[,] myData = 
  6             { 
  7             { "車牌號", "類型", "品 牌", "型 號", "顏 色", "附加費證號", "車架號" }, 
  8             { "浙KA3676", "危險品", "貨車", "鐵風SZG9220YY", "白", "1110708900", "022836" },
