C#关于导出excel的方法

一说到导出excel可能很多人都会觉得说直接利用ｎｐｏｉ　导入导出ｅｘｃｅｌ格式的文件，那样非常方便，但是可能有些时候有的浏览器不支持，那么该怎么办呢，现在介绍一种纯Ｃ#的导出ｅｘｃｅｌ的方法，代码如下：

 

  1 public void excel_output1(DataTable dt)

  2     {

  3         Response.Clear();

  4 

  5         Response.Buffer = true;

  6 

  7         Response.Charset = "utf-8 ";

  8         Response.AddHeader("Content-Disposition", "attachment;filename=" +

  9         HttpUtility.UrlEncode(DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls", System.Text.Encoding.UTF8));

 10         Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");

 11         Response.ContentType = "application/ms-excel";

 12         this.EnableViewState = false;

 13         System.IO.StringWriter sw = new System.IO.StringWriter();

 14 

 15         sw.WriteLine("<?xml version=\"1.0\"?>");

 16         sw.WriteLine("<?mso-application progid=\"Excel.Sheet\"?>");

 17         sw.WriteLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"");
