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""); 18 sw.WriteLine(" xmlns:o="urn:schemas-microsoft-com:office:office"");
