I have a C# code that basically uploads a file via FTP protocol (using FtpWebRequest ). I'd like, however, to first determine whether there is a working internet connection before trying to upload the file (since, if there isn't there is no point in trying, the software should just sleep for a time and check again). Is there an easy way to do it or should I just try to upload the file and in case it failed just try again, assuming the network connection was down? Just use the plain function System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable() that return true of false if the

First I asked that: ftp directory listing timeout. Huge number of subdirs . I got the answer. Still because I can have hundred thousands of FTP objects in the directory it could take really long time to scan that. However I thought it might be possible to retrieve all the objects that begin with 'A' and then 'B' and so on... As it retrieves directories it could start processing them on the other thread without waiting till it gets the entire list. Is it possible to do FTP directory listing with wildcards using standard FtpWebRequest ? The most recent update to the FTP specification (RFC 3659)

I'm writing an application that syncs files over an FTP site. Right now it's working by connecting through regular FTP, but now our IT guys want to set this up over a secure FTPS connection. They provided me with a *.cr_ certificate file. If I open the file in notepad I see something like this (but with real keys not foobar obviously). -----BEGIN RSA PRIVATE FOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBAR FOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBAR FOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBAR

I want to upload file from one server to another FTP server and following is my code to upload file but it is throwing an error as: The remote server returned an error: (550) File unavailable (e.g., file not found, no access). This my code: string CompleteDPath = "ftp URL"; string UName = "UserName"; string PWD = "Password"; WebRequest reqObj = WebRequest.Create(CompleteDPath + FileName); reqObj.Method = WebRequestMethods.Ftp.UploadFile; reqObj.Credentials = new NetworkCredential(UName, PWD); FileStream streamObj = System.IO.File.OpenRead(Server.MapPath(FileName)); byte[] buffer = new byte

I am trying to make a program that uploads/downloads .exe file to a FTP I tried using FtpWebRequest , but I only succeed to upload and download .txt files. Then i found here a solution for downloading using the WebClient : WebClient request = new WebClient(); request.Credentials = new NetworkCredential("username", "password"); byte[] fileData = request.DownloadData("ftp://myFTP.net/"); FileStream file = File.Create(destinatie); file.Write(fileData, 0, fileData.Length); file.Close(); This solution works. But I seen that WebClient has a method DownloadFile which did not worked. I think because

I can't find an example of a simple FTP access of a file anywhere, and the FTPClient class (which a couple of examples use) doesn't appear in the Android Class Index. I've got http access working, but how do I do a simple FTP get? All I want to do is download (for example): ftp://tgftp.nws.noaa.gov/data/observations/metar/stations/KABQ.TXT It shouldn't require login, change directory, etc. Just giving that URL to the http access methods don't seem to work. This is similar to the question at: unable to read file from ftp in android? I tried a simple: StringBuilder response = new StringBuilder()

I am being asked to support implicit and explicit FTPS (also known as FTPES). We are currently using the .NET FtpWebRequest . Does the FtpWebRequest support both types of FTPES, and what is the difference? Thanks as far as I know the current (.NET 2.0 and 3.5) version of FtpWebRequest supports Explicit SSL only. Actually, .NET 2.0 does not currently support implicit SSL, only explicit. We will consider adding this for a future release.

I trying upload file to a directory on a FTP server. I used this method with FtpWebRequest . I would like to upload one file to a home directory for this user, but I always get the following error message: The requested URI is invalid for this FTP command. What can be problem? I tried use passive mode off, but it still the same. static void FtpUpload() { // Get the object used to communicate with the server. FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://12.22.44.45"); request.Method = WebRequestMethods.Ftp.UploadFile; request.UsePassive = false; // This example assumes the
