  需要引用Excel COM 一般路径为(C:"WINDOWS"assembly"GAC"Office"11.0.0.0__71e9bce111e9429c"Office.dll)
 这里只是做一个简单的介绍,最基本使用到的一些属性。一般复杂的Excel格式,和大数据量多Sheet还时建议使用一个Excel的模版来实现,这样效率比较高。





生成以上图片格式Excel代码为:
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Office.Interop.Excel;
using System.Web;
using System.Collections;
