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="120px;" onclick="ExportExcel()" />
</div>
</body>
</html>
5、Home控制器代码
