如何更正AddToPost？

问题描述

我在创建博客时遇到问题。



问题在于PostsController代码的更新部分中的AddToPost，它无法识别AddToPost代码。我得到一个缺失的指令或汇编参考，有没有人有任何想法。我确实尝试用Add替换AddToPost，我得到了同样的错误，有什么建议吗？



代码如下：

I am having a problem creating a blog.

The problem is with the AddToPost in the update part of the PostsController code, it is not recognizing the AddToPost Code. I am getting a missing directive or assembly reference, does anyone have any ideas. I did try just replacing the AddToPost with Add, I got the same error, any suggestions?

The code is as follows:

public ActionResult Update(int? id, string title, string body, DateTime datetime, string tags)
        {
            if (!IsAdmin)
            {
                return RedirectToAction("Index");
            }

            Post post = GetPost(id);
            post.Title = title;
            post.Body = body;
            post.DateTime = datetime;
            post.Tags.Clear();

            tags = tags ?? string.Empty;
            string[] tagNames = tags.Split(new char[] { ' ' },                    StringSplitOptions.RemoveEmptyEntries);
            
            foreach (string tagName in tagNames)
            {
                post.Tags.Add(GetTag(tagName));
            }
            if (!id.HasValue)
            {
                model.AddToPosts(post);
            }

            model.SaveChanges();
            return RedirectToAction("Details", new { id = post.ID });
        }

谢谢，再次期待尽快收到您的回复。
