按模板导出Excel

说明：开发环境 vs2012 asp.net mvc4 c# 

         注意：Excel模板有多个sheet页，导出Excel的时候，同时给多个sheet页填充数据

 1、项目结构

3、Excel模板（注意sheet页的名称）

4、HTML代码（导出按钮）

      

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="EasyuiCombotree.aspx.cs" Inherits="MvcAppTest.EasyuiCombotree" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title>按模板导出Excel数据</title>

    <script type="text/javascript">

        function ExportExcel()
        {
            window.location.href = "Home/ExportExcel3";
        }
    </script>
</head>
<body>
  <div>
     <input type="button" value="导出Excel" style="width:120px;" onclick="ExportExcel()" />
  </div>    
</body>
</html>

5、Home控制器代码

public void ExportExcel3()
        {
            string path = Server.MapPath("~/loaclData/Excel/Student.xlsx");
            List<Room> myList = new List<Room>() { 
              new Room(){ ID=1, Name="班级1", Num=10},
              new Room(){ ID=2, Name="班级2", Num=20},
              new Room(){ ID=3, Name="班级3", Num=30},
              new Room(){ ID=4, Name="班级4", Num=40},
              new Room(){ ID=5, Name="班级5", Num=50}
            };
            var list01 = new List<object>() {    
                new { ID=1, Name="班级1", Num=10},
                new { ID=2, Name="班级2", Num=20},
                new { ID=3, Name="班级3", Num=30},
                new { ID=4, Name="班级4", Num=40},
                new { ID=5, Name="班级5", Num=50}};

       

            List<Company> comList = new List<Company>() {

            new Company(){ PID=6, ADDRICE="地块位置6", NAME="企业6",Price="pr6"}

            };
