在上篇博文中提到了C\#执行Excel宏模版的方法，这篇我们来介绍下怎么样将模版导出，并生成报表。

winform中简单的示例代码如下：

public ExportTextReport()

string strTempReportPath = "xxxxReport.xls";//导出报表的路径  
            string strTemplatePath = "xxxxTemplate.xls";//报表模版的路径

FileInfo fi = new FileInfo(strTempReportPath);

ExcelTest.ExelTemplate.FillContent(strTemplatePath, strTempReportPath, dsData);

if (File.Exists(strTempReportPath))  
            \{  
                System.Diagnostics.Process.Start("Excel.exe",strTempReportPath); //打开EXCEL  
            \}

在Asp.net中我们可以专门做一个导出报表的页面来进行报表的导出，代码如下：

<%@ Page Language="C\#" AutoEventWireup="true" CodeBehind="AttachPrint.aspx.cs" Inherits="Common.AttachPrint" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd][http_www.w3.org_TR_xhtml1_DTD_xhtml1-transitional.dtd]">

<html xmlns="[http://www.w3.org/1999/xhtml][http_www.w3.org_1999_xhtml]" >  
<head runat="server">  
    <title>Untitled Page</title>  
</head>  
<body>  
    <form id="form1" runat="server">  
    <div>  
     
    </div>  
    </form>  
</body>  
</html>

using System;  
using System.Data;  
using System.Configuration;  
using System.Collections;  
using System.Web;  
using System.Web.Security;  
using System.Web.UI;  
using System.Web.UI.WebControls;  
using System.Web.UI.WebControls.WebParts;  
using System.Web.UI.HtmlControls;  
using System.IO;

namespace Common  
\{  
    public partial class AttachPrint : System.Web.UI.Page  
    \{  
        protected void Page\_Load(object sender, EventArgs e)  
        \{  
             if(!string.IsNullOrEmpty(Request.QueryString\["PrintFile"\]))  
             \{  
                 string realFullFileName = Server.HtmlDecode(Request.QueryString\["PrintFile"\]);  
                 FileInfo finfo = new FileInfo(realFullFileName);  
                 Response.Clear();  
                 Response.Charset = "utf-8";  
                 Response.Buffer = true;  
                 this.EnableViewState = false;  
                 Response.ContentEncoding = System.Text.Encoding.UTF8;

Response.AppendHeader("Content-Disposition", "attachment;filename="  
                 + HttpUtility.UrlEncode(finfo.Name, System.Text.Encoding.UTF8));  
                 Response.WriteFile(realFullFileName);  
                 Response.Flush();  
                 Response.Close();  
                 Response.End();  
             \}  
        \}  
    \}  
\}

然后在其它页面进行报表导出时示例方法如下：

private ExportTest()

string strTempReportPath = "xxxxReport.xls";//导出报表的路径  
            string strTemplatePath = "xxxxTemplate.xls";//报表模版的路径

FileInfo fi = new FileInfo(strTempReportPath);

ExcelTest.ExelTemplate.FillContent(strTemplatePath, strTempReportPath, dsData);

string strexportpath = Server.HtmlEncode(strTempReportPath);  
            Response.Redirect(string.Format("AttachPrint.aspx?PrintFile=\{0\}", strexportpath), true);
