通过ASP.NET损坏的文件的远程文件下载 [英] Remote file Download via ASP.NET corrupted file

问题描述

我使用的是code下面我已经在论坛上的一个发现，下载远程服务器上的文件。现在看来，这是工作。然而，下载的文件被破坏，我不能解压缩。

你有任何想法，为什么会这样？或者，如果我的做法是错误的，你能不能给我建议一个更好的办法吗？

 保护无效的Page_Load（对象发件人，EventArgs的发送）
    {        字符串的URL = \"http://server/scripts/isynch.dll?panel=AttachmentDownload&NoteSystem=SyncNotes&NoteType=Ticket&NoteId=1&Field=supp&File=DisplayList%2etxt\";
        HttpWebRequest的REQ =（HttpWebRequest的）WebRequest.Create（URL）;
        req.Credentials =新的NetworkCredential（用户，传）;
        HttpWebResponse RESP =（HttpWebResponse）req.GetResponse（）;
        ////初始化输出流
        Response.Clear（）;
        Response.ContentType =应用程序/八位字节流;
        Response.AppendHeader（内容处置，附件;文件名=+DisplayList.txt）;
        Response.AppendHeader（内容长度，resp.ContentLength.ToString（））;        ////填充输出流
        字节[] = ByteBuffer中新的字节[resp.ContentLength]
        流RS = req.GetResponse（）GetResponseStream（）。        rs.Read（ByteBuffer的，0，ByteBuffer.Length）;
        Response.BinaryWrite（ByteBuffer的）;
        Response.Flush（）;        ///清理
        到Response.End（）;
        rs.Dispose（）;
    }

I am using the code below which I have found on one of the forums to download a file in remote server. it seems it is working. However, the downloaded file is corrupted and I cannot unzip.

Do you have any idea why it is so? or if my approach is wrong, could you suggest me a better way please?

     protected void Page_Load(object sender, EventArgs e)
    {

        string url = "http://server/scripts/isynch.dll?panel=AttachmentDownload&NoteSystem=SyncNotes&NoteType=Ticket&NoteId=1&Field=supp&File=DisplayList%2etxt";
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.Credentials = new NetworkCredential("user", "pass");
        HttpWebResponse resp = (HttpWebResponse)req.GetResponse();


        ////Initialize the output stream
        Response.Clear();
        Response.ContentType = "application/octet-stream";
        Response.AppendHeader("Content-Disposition:", "attachment; filename=" + "DisplayList.txt");
        Response.AppendHeader("Content-Length", resp.ContentLength.ToString());

        ////Populate the output stream
        byte[] ByteBuffer = new byte[resp.ContentLength];
        Stream rs = req.GetResponse().GetResponseStream();

        rs.Read(ByteBuffer, 0, ByteBuffer.Length);
        Response.BinaryWrite(ByteBuffer);
        Response.Flush();

        ///Cleanup
        Response.End();
        rs.Dispose();
    }
