File Download Tips for asp.net

• use http header
• protected void Page_Load(object sender, EventArgs e) { string format = Convert.ToString(ViewData["format"]); Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode("费用报销表", Encoding.UTF8) + string.Format(".{0}",format)); //测试中发现：如果要想在IE中直接打开PDF，上行代码，不能有！！否则即使客户端有设置，也会使用 Adobe Reader/Acrobat 打开 Response.ContentType = string.Format("application/{0}",format); Response.Charset = "GB2312"; Response.ContentEncoding = System.Text.Encoding.UTF8; Response.BinaryWrite(ViewData.Model); Response.Flush(); //prevent render html to client(critical) Response.End();  

 

 

•  request to doc directly

          Response.Redirect(“http://localhost:2222/Docs/abc.doc”, true);

 

Tips:

  至于客户端使用浏览器打开(当然必须要相应的浏览器插件支持)，还是相应的application (MS-Word,Adobe Reader),打开前是否提示下载，Server端是无法控制的，这个和用户设置有关系。见图
