Upload Filet to FTP return Error

Whe I try to upload a file to an FTP Server I always get an error on "ftpWebRequest.GetRequestStream();"

The Error is:

System.Net.ProtocolViolationException: Can not send content-body with this verb-type
at System.Net.FtpWebRequest.GetRequestStream()

I cannot find the problem in my code which is the following:

public void ftpUploadFile(Filename _file)
{
    System.IO.Stream        ioStream;
    System.IO.StreamReader  ioStreamReader, responseReader;
    System.String           strReadLine;
    System.Text.Encoding    utf8;
    System.Byte[]           bytes;
    FileIOPermission        permission;

    FilePath filePathDest;
    int length;
    ;
    if (_file != '')
    {
        try
        {
            permission = new FileIOPermission(_file,"RW");
            permission.assert();

            // BP Deviation Documented
            ioStreamReader = new System.IO.StreamReader(_file);
            utf8 = System.Text.Encoding::get_UTF8();

            if (ioStreamReader)
            {
                bytes = utf8.GetBytes( ioStreamReader.ReadToEnd() );

                ioStreamReader.Close();
                
                // Marshaling .NET to X++
                ftpObject = System.Net.WebRequest::Create(ftpHostName + @"/" + _file);
                ftpWebRequest = ftpObject;
                if (ftpWebRequest)
                {
                    ftpWebRequest.set_KeepAlive(false);
                    ftpWebRequest.set_UsePassive(true);
                    ftpWebRequest.set_Method(#UploadFile);
                    ftpWebRequest.set_UseBinary(true);
                    ftpWebRequest.set_Timeout(ftpTimeOut);
                    ftpWebRequest.set_ReadWriteTimeout(ftpTimeOut);
                    ftpWebRequest.set_ContentLength(bytes.get_Length());
                    this.setFTPCredentials();

                    ioStream = ftpWebRequest.GetRequestStream();
                    ioStream.Write(bytes, 0, bytes.get_Length());
                    ioStream.Close();
                    
                    webResponse = ftpWebRequest.GetResponse();
                    
                    responseReader = new System.IO.StreamReader(webResponse.GetResponseStream());
                    
                    info(responseReader.ReadToEnd());
                    
                    webResponse.Close();
                }
                 CodeAccessPermission::revertAssert();
            }
        }
        catch(Exception::CLRError)
        {
            exception = CLRInterop::getLastException();
            if(exception != null)
            {
                exception = exception.get_InnerException();
                checkFailed(exception.ToString());
            }
        }
    }
}

Any Ideas?
