How do I Reply a Comment So it can capture the comment

public ActionResult Quote(int? id)
       {
           var user = User.Identity.Name;
           var userId = WebSecurity.CurrentUserId;
           //var userId = db.UserProfiles.FirstOrDefault(x => x.UserName == user).UserId;
           if (User.Identity.Name == null)
           {
               return RedirectToAction("Login", "Account");
           }
           if (id == null)
           {
               return RedirectToAction("topics", "forum");
           }

           //var p = db.Posts.FirstOrDefault(x => x.PostId == id.Value);
           var post = db.Posts.Find(id.Value);

           var comment = db.UserComments.FirstOrDefault();
           var usercomment = db.UserComments.Find(comment.UserCommentId);

           if (usercomment == null)
           {
               return RedirectToAction("topics");
           }

           return View(new Quote { UserId = WebSecurity.CurrentUserId, PostId = id.Value, UserCommentId = usercomment.UserCommentId });
       }
