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("");

77 writer.Write(eachCloumn.ColumnName.ToString());
78 writer.WriteLine(" | ");
79 }
80 writer.WriteLine("

81
82 //生成数据记录
83 foreach (DataRow eachRow in dsBook.Tables[0].Rows)
