Hi,

I have a question regarding file downloading via FtpWebRequest. All works well when I download the needed files, but if the filename has a space in it, the filename is saved with %20 replacing the actual space (eg. remote/folder/my file.whatever becomes local\folder\my%20file.whatever. If I do a file listing of where the file is, it does not contain the encoded character in the result.

I know there is probably something silly/small that I am missing, but I'm pulling (what little is left of) my hair out!

Barring creating a helper class to find/replace the offending characters in the newly downloaded file, is there something that I can do when the file is saved that will resolve this issue?

My code is something as follows:
FtpWebRequest request = FtpWebRequest.Create(myUriWithFileName) as FtpWebRequest;
request.Method = WebRequestMethods.Ftp.DownloadFile;
request.Credentials = new NetworkCredential(username, password); // credentials as necessary...
request.UsePassive = false;//or true as is necessary
request.UseBinary = true;
using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
using (Stream responseStream = response.GetResponseStream())
{
    StreamToFile(responseStream, @"c:\Temp\my file.whatever"); // StreamToFile is just a helper to write from one stream to another...
}

Thanks in advance!

%20 is the hex value for the space character - it is a good thing to have it there instead of a space, especially if you are going to create links or URL's with it.

Hi,

I am not creating links/URLs and I know that that is the hex value for the space character. My issue is that I am downloading a file which has a space in it's name and when I do a file listing of the folder it is returned correctly (without the encoded/hex value), but when it saves the file with that file name it replaces it with the %20.

My question was how to mitigate this file name change without resorting to a helper method to change the file name back to spaces (after it has saved onto my local system).

Well, ok, but I don't think you need to create a helper method - can't you just use Server.UrlDecode to do it?

Thanks for your response,

I should have mentioned (apologies), that this is a windows service and/or desktop application and not a web-based application.

You can still use the WebUtility class for this

Thanks Wombaticus,

I will have a look see at that one and advise.

Hi Wombaticus,

Thanks for your suggestions. Instead of fighting with all that stuff, I ended up using a third party component that did what I needed it to do.
Thanks once again for your input. It is/was greatly appreciated!
Cheers!

The problem is most likely within your StreamToFile method, which you haven't shown.

1 solution

Thanks one and all, as noted above I ended up using a third party component to do what I needed it to do.

Cheers!
