文件下载的功能怎么做,怎样支持用迅雷下载的?

[CodeShow]

我的代码如下,但只能用"另存为"下载:

string abcName = "abc.rar";  //文件名
string dName = "~/upload/" + abcName;  //路径
string filepath = Server.MapPath(dName);
string filename = Path.GetFileName(filepath);

Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(abcName, System.Text.Encoding.UTF8));  
Response.WriteFile(filepath);

请问怎么写才能支持迅雷?

直接用超级链接，点击就能用迅雷下载，还能另存为，最多中转个页面，做些判断，下个文件，不用那么复杂吧？我做错了吗？

关注一下，怎么支持迅雷还真没做过

[q704174307]

楼上的，厉害，我觉得好像不用设置吧，浏览器默认使用迅雷下载就能了，我是这样过来的

一行代码就可以了。

你这个类怎么用的
public static bool DownLoadFile(HttpRequest MyRequest, HttpResponse MyResponse, string MyFileName, string MyFullPath, long MySpeed)

我对Asp.Net还不够熟悉,请问一下MyRequest,MyResponse这两个参数怎么传值的?

你也太绝了吧 做些网站是给别人用 而不是自己用！ 难道对所有的用户都说把“浏览器默认使用迅雷下载”吗！
