I am using this code to upload file to FTP server:

        String source = @"E:\\file\e1.txt";
        String ftpurl = @"http://ift.tt/1ywnh1j";
        String ftpusername = @"myusername@myftpserver.pl";
        String ftppassword = @"mypassword";

        string filename = Path.GetFileName(source);
        string ftpfullpath = ftpurl + "/" + filename;
        Debug.WriteLine("Uploading...");

        var fs = File.OpenRead(source);

        FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
        ftp.Credentials = new NetworkCredential(ftpusername, ftppassword);
        ftp.Timeout = -1;
        ftp.KeepAlive = true;
        ftp.UseBinary = true;
        ftp.Method = WebRequestMethods.Ftp.UploadFile;

        Stream ftpstream = ftp.GetRequestStream();
        fs.CopyTo(ftpstream); 
        ftpstream.Close();


        Debug.WriteLine("Upload complete.");

File is quit big - about 50 mb. So, after uploading the file, appliaction hangs. Here is an output in debug window

Uploading... //immediately after executing the code
The thread 0xd50 has exited with code 0 (0x0). //after some time

And it never prints:

Upload complete.

Note, that after thread exits, upload is still in progress, it's not cancelled. I have noticed this problem, when I was trying to send multiple files from List in a loop - application hangs after uploading first file. Can someone help me?
