I tried the above code to list the files of directory from ftp server and then download them in c#.. but the following code does not execute.. i dont know why.. can anybody help for me?

foreach (string fileName in collectionOfFiles)
                {
                    Console.WriteLine("for statment");
                    string fullPathDestionation = Path.Combine(destionationLocation, Path.GetFileNameWithoutExtension(fileName) + ".*");
                    fDownloader.downloadFile(ftpServer, fileName, userName, password, fullPathDestionation);
                }

Look at the bottom of your code, just above the line that says "Console.WriteLine("downloaded");". I see a catch block that only has a comment that says "write to log". Is that how it is in your code? If so, then you are ignoring errors. Put a Console.WriteLine in the catch block and show the error message. You say that the code does not execute, but probably it executes and gets an error and your program ignores the error.
