Hi!

i'm trying to upload a file to localhost using FTP with below code. i get error: "Unable to connect to the remote server" on

Stream requestStream = request.GetRequestStream();

What i'm doing wrong? i'm using xamp as the local server.

// Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://localhost/");
            request.Method = WebRequestMethods.Ftp.UploadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential("root", "");

            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader("test.txt");
            byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = fileContents.Length;

            Stream requestStream = request.GetRequestStream();
            requestStream.Write(fileContents, 0, fileContents.Length);
            requestStream.Close();

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

            response.Close();

Thanks.

It would be helpful if you tell us what error you get.

You don't have an FTP server running on localhost, or the firewall is blocking inbound requests to the localhost's FTP port?

i installed IIS and set up an ftp server, and tried to upload the file to the server folder. But now i get the error: "The requested URI is invalid for this FTP command.", at the same line as previous. (My server is running i can access it with the browser.)

Code:

// Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://10.224.213.152/"); // Tried ftp://localhost/ too, without success
            request.Method = WebRequestMethods.Ftp.UploadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential("Kasun Liyanage", "mypass");

            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader("test.txt");
            byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = fileContents.Length;

            Stream requestStream = request.GetRequestStream();
            requestStream.Write(fileContents, 0, fileContents.Length);
            requestStream.Close();

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

            response.Close();

I believe you will need to provide a file name to save to on the server in your URL.

See this, which is the first link of a Google search of this error. Please learn to use Google first to fix your problems. If you get an error, guess what...you're probably not the first person on the planet to get that error.

Ok thank i managed to upload a file into a remote web server.

Code:

// Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://kasunl.worlditsme.com/voo.txt");
            request.Method = WebRequestMethods.Ftp.UploadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential("kasunl", "mypass");

            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader("test.txt");
            byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = fileContents.Length;

            Stream requestStream = request.GetRequestStream();
            requestStream.Write(fileContents, 0, fileContents.Length);
            requestStream.Close();

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

            response.Close();

But i can not figure out or find a answer on web to why uploading to localhost cause errors. Latest error: The underlying connection was closed: The server committed a protocol violation.

// Get the object used to communicate with the server.
            FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://localhost/voo.txt"); // Tried ftp://localhost/ too, without success
            request.Method = WebRequestMethods.Ftp.UploadFile;

            // This example assumes the FTP site uses anonymous logon.
            request.Credentials = new NetworkCredential("KasunL", "mypass");

            // Copy the contents of the file to the request stream.
            StreamReader sourceStream = new StreamReader("test.txt");
            byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
            sourceStream.Close();
            request.ContentLength = fileContents.Length;

            Stream requestStream = request.GetRequestStream();
            requestStream.Write(fileContents, 0, fileContents.Length);
            requestStream.Close();

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

            response.Close();

Ok i did figure out how to do it and made a quick blog post for future reference, and for any ftp newbie that might be in the same trouble as was me.
