将文件保存到远程服务器MVC5

Question

我正在尝试将文件上传到远程服务器。我在本地服务器（机器A）上有这个MVC5站点，文件应该转到另一台服务器（机器B）。

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Id,Email,FirstName,LastName,DOB,Gender,AutoLogin,Password,ScreenName,NotificationsOn,ThumbnailURL")] User user, IEnumerable<HttpPostedFileBase> files)
    {
        HttpPostedFileBase photo = Request.Files[0];
        if (photo != null)
        {
            //do some stuff with the file, like limit size and extensions

            //smp = localhost folder (machine A) and I need the remote folder(machine B). 
            //How do I do this? If I need FTP, how to connect?
            string smp = Server.MapPath("~/UserContent/");
            photo.SaveAs(smp" + photo.FileName);
        }
        if (ModelState.IsValid)
        {
            db.Users.Add(user);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        return View(user);
    }
