Question

I’m trying to read a txt file from a ftp server and I’m getting a “550 File not found.” error even I’m %100 sure that the file is there.

Here are the variations for URI I’ve tried:

ftp://server/MySubFolder/MyFile.txt
ftp://server/%2fMySubFolder/MyFile.txt
ftp://server/MySubFolder/%2fMyFile.txt
ftp://server/%2fMySubFolder/%2fMyFile.txt
ftp://server/%2f/MySubFolder/MyFile.tx
ftp://server/MySubFolder/%2f/MyFile.txt
ftp://server/%2f/MySubFolder/%2f/MyFile.txt

They all return the same result page:

200 Type set to I.
200 PORT command successful.
550 The system cannot find the path specified.

Here’s the code I’m trying:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(file);
request.Method = WebRequestMethods.Ftp.DownloadFile;
request.Credentials = new NetworkCredential(username, password);

FtpWebResponse response = (FtpWebResponse)request.GetResponse();

Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);

string content = reader.ReadToEnd();

reader.Close();
response.Close();

I also tried calling SetMethodRequiresCWD before creating my FtpWebRequest objects but it didn’t help either.

My application is a .NET 4.0 Client Profile Windows Service.

I’d appreciate any help.

Solved this problem like this: The server the service is running on is a Hyper-X virtual machine. Somehow the VM acts like a proxy. I added request.Proxy = null; to my requests and both upload and download works now.
