ASP.NET 如何导出excel（二）
在上一篇 ASP.NET 如何导出excel（一）中介绍了导出html格式的excel文件的方法。本篇介绍另一种方法：导出xml格式的excel文件。该方法比上一种方法更具有通用性，功能也更强大，他可以导出多个工作表，并且支持各种样式以及常用的公式，不过也有缺点，就是不能包含图片以及图表。
一）确定要导出的excel文件的格式
我们可以先制作一个excel文件做为模板，他包含了要导出的格式，如：
然后选择 “文件”/ “另存为” 保存为xml表格，用记事本打开保存的xml文件，就可以看到他的内容了：
<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>

这是一个标准的xml文件，可以用excel打开，同时也支持open office。
二 根据模板的内容编写输出流
Response.AddHeader("Content-Disposition", "attachment;filename=" +
HttpUtility.UrlEncode(DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls",
System.Text.Encoding.UTF8));
Response.ContentEncoding = System.Text.Encoding.Default;
Response.ContentType = "application/ms-excel";
System.IO.StringWriter sw = new System.IO.StringWriter();
sw.WriteLine("<?xml version=\"1.0\"?>");
sw.WriteLine("<?mso-application progid=\"Excel.Sheet\"?>");
sw.WriteLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"");
sw.WriteLine(" xmlns:o=\"urn:schemas-microsoft-com:office:office\"");
sw.WriteLine(" xmlns:x=\"urn:schemas-microsoft-com:office:excel\"");
sw.WriteLine(" xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\"");
sw.WriteLine(" xmlns:html=\"http://www.w3.org/TR/REC-html40\">");
sw.WriteLine("<Worksheet ss:Name=\"Sheet1\">");
// ........
sw.WriteLine("</Worksheet>");
sw.WriteLine("</Workbook>");
Response.Write(sw);
Response.End();
