ASP.NET C# upload MemoryStream content via FTPwebRequest issue

问题

This should be pretty straight forward, and uploading works. BUT when I open the uploaded file on the FTP server it shows binary data which is just some weird characters that look like this [][][][], and its the right file size. how do I add attributes or headers that that will say that this file is an XML?

    public bool ProcessBatch(MemoryStream memStream)
    {
        bool result = true;
        FTPaddress = DistributionResources.ftpServer;
        CompleteFTPPath = DistributionResources.ftpPath;

        request = (FtpWebRequest)FtpWebRequest.Create(FTPaddress + CompleteFTPPath);
        request.Credentials = new NetworkCredential("username", "password");
        request.Method = WebRequestMethods.Ftp.UploadFile;
        request.UsePassive = true;
        request.UseBinary = true;
        request.KeepAlive = false;

        try
        {

            byte[] buffer = new byte[memStream.Length];

            memStream.Read(buffer, 0, buffer.Length);
            memStream.Close();

            using (Stream reqStream = request.GetRequestStream())
            {
                reqStream.Write(buffer, 0, buffer.Length);
            }

            //Gets the FtpWebResponse of the uploading operation
            response = (FtpWebResponse)request.GetResponse();
            Console.WriteLine(response.StatusDescription); //Display response

        }
        catch(Exception ex)
        {
            result = false;
        }

        return result;
    }

Thank you very much

回答1:

Try not using request.UseBinary = true

In other words, use request.UseBinary = false. Otherwise it will upload the contents as binary data, which is likely why you are seeing it show up that way on the server.

For example, if you use the command line FTP client in windows, you have to explicitly type ascii before puting a text file. Same principle likely applies here.
