思归大哥帮帮我啊，我请你听歌～～～

我想用Response.WriteFile();防盗链播放MP3，为什么每次运行都弹出提示打开或者保存，而不能直接播放
这个问题的我上一个帖子：http://expert.csdn.net/Expert/topic/2365/2365649.xml?temp=.7590601

每次弹出一个文件下载对话框，让我打开，保存，或者取消。
而我在网页上直接打开一个http的mp3地址，都可以直接播放的。

我的代码是这样写的，请指点：

FileInfo file = new System.IO.FileInfo("E:\\Songs\\apengyouzaijia.rm");

Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/octet-stream";


Response.WriteFile(file.FullName);

Response.End();

这样做好像什么文件都是可以下载的。
连text　html 类型的文件都会是弹出下载的窗口.

是啊，连 .aspx 文件都会弹出下载窗口，请问有更好的解决方法吗？

you are sending the wrong content-type, try

ContentType="audio/x-pn-realaudio"

or

application/vnd.rn-realmedia

还是不行，思归大哥，要么页面显示一对乱码，要么还是提示下载，
还是听歌吧 最近被我女孩拒绝了，喜欢听这首歌http://www.paifang.com/go/mm/mtv0203.rm

Response.Clear();

Response.End();

FileInfo file = new System.IO.FileInfo("E:\\煤炭网程序\\Songs\\apengyouzaijia.rm");

// clear the current output content from the buffer
Response.Clear();
// add the header that specifies
Response.AddHeader("Content-Disposition", "filename=" + file.Name);
// add the header that specifies the file size, so that the browser
// can show the download progress
Response.AddHeader("Content-Length", file.Length.ToString());
// specify that the response is a stream that cannot be read by the
// client and must be downloaded

string fileName = file.Name.ToLower();
int lastIndex = fileName.LastIndexOf(".");
fileName = fileName.Substring(lastIndex);

// 根据文件后缀指定文件的Mime类型
switch (fileName)
{
case ".rm":
Response.ContentType = "application/vnd.rn-realmedia";
break;
case ".mp3":
Response.ContentType = "audio/mpeg3";
break;
case ".asf":
Response.ContentType = "video/x-ms-asf";

case "mpeg":

}

// send the file stream to the client
Response.WriteFile(file.FullName);
// stop the execution of this page
Response.End();

哈哈，解决了

[skyover]

Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);

这行干掉。
