FTP Download Function

This is an function that downloads a single file from an FTP server and saves it to disk
This is my first time doing anything with FTP, please let me know if i have missed anything.

public void DownloadFile(string fileloc, string saveLoc)
{
    try
    {
        // Get the object used to communicate with the server.
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(fileloc);
        request.Method = WebRequestMethods.Ftp.DownloadFile;

        request.Credentials = new NetworkCredential(Username, Password);

        using (var response = (FtpWebResponse)request.GetResponse())
        {
            using (var fileStream = File.Create(saveLoc))
            {
                response.GetResponseStream().CopyTo(fileStream);
            }
        }
    }
    catch (Exception EX)
    {
        throw EX;               
    }
}

First, like ANeves said, the only thing your catch does is that it resets the exception's stack trace, which is not what you want to do. Just remove the try/catch completely, it serves no purpose here.

Second, I don't see any reason to use WebRequest here, using WebClient is much simpler.

Also, you might want to have better parameter names: fileloc doesn't say what exactly it is, and doesn't use the usual capitalization. And loc is unnecessarily abbreviated (you're not trying to write a Twitter post where every character counts, readability is more important) and too ambiguous.

public void DownloadFile(string url, string savePath)
{
    var client = new WebClient();
    client.Credentials = new NetworkCredential(Username, Password);
    client.DownloadFile(url, savePath);
}

This method could be rewritten as one expression, but I probably wouldn't do that:

public void DownloadFile(string url, string savePath)
{
    new WebClient { Credentials = new NetworkCredential(Username, Password) }
        .DownloadFile(url, savePath);
}
