问是否将RedirectToAction返回到索引，但带有href部分？(Ajax可选)

 public class UserViewModel
    {
        public List<Timeline> TheTimeline { get; set; }
        public List<Posts> ThePosts{ get; set; }
        public string SettingsVM{ get; set; }
    }

 [HttpPost]
        public ActionResult SettingsUpdateProfile(User variable, IFormFile TheEmployeePicture)
        {
          blablabla
                    if (UploadFile(TheEmployeePicture, fname))
                    {
                        return RedirectToAction(String.Format("Index/{0}", User.Identity.Name);
                    }
                    else
