(转)ASP.NET读出XML数据生成Excel

概要描述:读取XML数据,最终生成Excel数据。
一.新建一个book.xml,代码内容如下:

 1<?xml version="1.0" encoding="utf-8" ?>
 2<bookstore xmlns="http://tempuri.org/Book.xsd">
 3  <book genre="autobiography" publicationdate="1981" ISBN="1-861003-11-0">
 4    <title>C# Program</title>
 5    <author>
 6      <first-name>Wang</first-name>
 7      <last-name>Lei</last-name>
 8    </author>
 9    <price>10</price>
10  </book>
11  <book genre="novel" publicationdate="1967" ISBN="0-201-63361-2">
12    <title>VB.Net Program</title>
13    <author>
14      <first-name>James</first-name>
15      <last-name>Wang</last-name>
16    </author>
17    <price>8</price>
18  </book>
19  <book genre="philosophy" publicationdate="1991" ISBN="1-861001-57-6">
20    <title>Sql server 2005 database manager</title>
21    <author>
22      <first-name>Elvis</first-name>
23      <last-name>Yu</last-name>
24    </author>
25    <price>5</price>
26  </book>
27</bookstore>
二.新建一个Default.aspx的页面,在Default.aspx页面上拖放一个按钮,双击进入按钮的事件,代码如下:
  1using System;
  2using System.Data;
  3using System.Configuration;
  4using System.Web;
  5using System.Web.Security;
  6using System.Web.UI;
  7using System.Web.UI.WebControls;
  8using System.Web.UI.WebControls.WebParts;
  9using System.Web.UI.HtmlControls;
 10using System.IO;
 11
 12public partial class _Default : System.Web.UI.Page 
 13{
 14    protected void Page_Load(object sender, EventArgs e)
 15    {
 16
 17    }

 18    protected void Button1_Click(object sender, EventArgs e)
 19    {
 20        try
 21        {
 22            //要转换的XML文件
 23            string XMLFileName = Path.Combine(Request.PhysicalApplicationPath, "book.xml");
 24            DataSet dsBook = new DataSet();
 25            dsBook.ReadXml(XMLFileName);
 26            int rows = dsBook.Tables[0].Rows.Count + 1;
 27            int cols = dsBook.Tables[0].Columns.Count;
 28
 29            //将要生成的Excel文件
 30            string ExcelFileName = Path.Combine(Request.PhysicalApplicationPath, "book.xls");
 31            if (File.Exists(ExcelFileName))
 32            {
 33                File.Delete(ExcelFileName);
 34            }

 35            StreamWriter writer = new StreamWriter(ExcelFileName, false);
 36            writer.WriteLine("<?xml version=\"1.0\"?>");
 37            writer.WriteLine("<?mso-application progid=\"Excel.Sheet\"?>");
 38            writer.WriteLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"");

 69            writer.WriteLine(" <Worksheet ss:Name=\"MyReport\">");
 70            writer.WriteLine(string.Format("  <Table ss:ExpandedColumnCount=\"{0}\" ss:ExpandedRowCount=\"{1}\" x:FullColumns=\"1\"", cols.ToString(), rows.ToString()));
