FtpWebRequest

Hi,
I'm using VS2010 and .Net Framework 4.0.

I have done quite a bit of work with VB.Net, but just recently decided to work with C# to learn some new things. We still have a legacy system that I need to communicate with to kick off a job. I've done this in the past with VB.Net using the Shell command and it works quite well. I can't find that the Shell command is available with C#, so I've been trying to use the FtpWebRequest. Can someone help me out here? Below is what works for me in VB.Net and below that is what I'm trying to use for C#. qc_jcl4.txt is the file I'm sending up.

            Using swFTP As StreamWriter = New StreamWriter(psFilePath & "qc_ftp4.txt")
                swFTP.WriteLine("open mfvipa.amgreetings.com")
                swFTP.WriteLine(sLogonId)
                swFTP.WriteLine(sPass)
                swFTP.WriteLine("quote site filetype=jes")
                swFTP.WriteLine("quote site jesl=155")
                swFTP.WriteLine("put " & """" & psFilePath & "qc_jcl4.txt" & """")
                swFTP.WriteLine("close")
                swFTP.WriteLine("quit")
            End Using

            Shell(psFTPpath & " -s:" & """" & psFilePath & "qc_ftp4.txt" & """")

                // Get the object used to communicate with the server.
                FtpWebRequest request = (FtpWebRequest)WebRequest.Create("mfvipa.amgreetings.com");
                request.Method = WebRequestMethods.Ftp.UploadFile;

                // FTP site logon.
                request.Credentials = new NetworkCredential(sLogonID, sPass);

                // Copy the contents of the file to the request stream.
                StreamReader sourceStream = new StreamReader(@"C:\Users\dcastling\jclDC11ID3.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();

                Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);

                response.Close();

The URI you pass to WebRequest.Create needs to be the full URI, including the path and filename of what should be created on the server.

Just to clarify, VB and C# compile to the same code, and it's mostly new syntax what you're now learning (almost a 1 on 1 translation of what you're used to do in VB). Therefore the easy solution would be from @Carl_Tawn.
But if you really want to learn new stuff, continue with what you were doing and fix this line:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("mfvipa.amgreetings.com");

to
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://mfvipa.amgreetings.com/jclDC11ID3.txt");

Thanks for the quick replies guys!

I had actually started out trying what Carl is suggesting. The way I had it set up, the ftp prompt would open and show msg Unknown host C:\Users\dcastling\DC11ID3ftp.txt.
The file DC11ID3ftp.txt contains the line commands to pass to the ftp prompt.

I changed the URI as suggested. I'm getting an exception on line Stream requestStream = request.GetRequestStream();
The remote server returned an error: (501) Syntax error in parameters or arguments.

So I'm trying to figure out what's going on with that...
