I am using C# to upload some file to a ftp server. If the file already existed the FtpWebRequest timed out, so I thought to deleate it first.

However the WebRequestMethods.Ftp.DeleteFile also always times out. Am I doing something wrong?

Here is my code:

FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(address);

request.Credentials = new NetworkCredential(Username, Password);
request.KeepAlive = false;
request.Method = WebRequestMethods.Ftp.DeleteFile;

try
{
    FtpWebResponse resp = (FtpWebResponse)request.GetResponse();
}
catch (Exception e)
{
    ...         
}

EDIT: Oh and it doesn’t matter witch file I am trying to delete. As long as the file exists the request will always time out. If the file doesn’t exist a different exception is thrown.

Nothing is wrong with credentials, I can do other operations (upload/download without a problem). Also it’s not a server problem, if I connect to it with a client (FileZilla) with the same username / pass everything works as it should.

Thank you for your help.

    The thing I have found using this Ftp via FtpWebRequest, is it is inherently a lot slower (since it is using the HTTP protocol over port 80), and it drives me crazy because FileZilla can do it a lot quicker (obviously using FTP protocol over port 20/21). There is a open source ftp component found here, I do not know if it will work for you, but worth a shot.

    I know this is a subjective answer that will get downvoted, but personally, using ftp over port 80 is bound to be a lot slower especially on file operations like what you are trying to achieve.
