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：
public void excel_output1(DataTable dt)
{
Response.Clear(); Response.Buffer = true; Response.Charset = "utf-8 ";
Response.AddHeader("Content-Disposition", "attachment;filename=" +
HttpUtility.UrlEncode(DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls", System.Text.Encoding.UTF8));
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
Response.ContentType = "application/ms-excel";
this.EnableViewState = false;
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\"");
