复制代码 代码如下:
<%@ WebHandler Language="C#" Class="Handler" %>
using System;
using System.Web;
public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
string fileName = "web.config";//客户端保存的文件名
string filePath = context.Server.MapPath("web.config");//路径
//以字符流的形式下载文件
System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Open);
byte[] bytes = new byte[(int)fs.Length];
fs.Read(bytes, 0, bytes.Length);
fs.Close();
context.Response.ContentType = "application/octet-stream";
//通知浏览器下载文件而不是打开
context.Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
context.Response.BinaryWrite(bytes);
context.Response.Flush();
context.Response.End();
}
public bool IsReusable {
get {
return false;
}
}
}
