Question

我有以下课程

Post.cs

public class Post: Neo4jEntity
    {
        public Post()
        {
            Label = "Post";
            ID = Guid.NewGuid();
        }
        public Guid ID { get; set; }
        public DateTime DateCreation { get; set; }
        public string Content { get; set; }
    }

Comment.cs

    public class Comment:Neo4jEntity
        {
            public Comment()
            {
                Label = "Comment";
                ID = new Guid();
            }
            public Guid ID { get; set; }
            public string Content{ get; set; }
            public DateTime CreationDate{ get; set; }

        }

ApplicationUser.cs

public class ApplicationUser:IdentityUser
        {
            public ApplicationUser()
            {
                Label = "ApplicationUser";
            }
            public string FirstName{ get; set; }
            public string SecondName{ get; set; }
            public Sex Sex{ get; set; }//enum


        }

我想从具有添加了ApplicationUser的评论的数据库所有帖子中获取。

 var posts = _graphClient.Cypher
                    .Match("(user:ApplicationUser)-[:POST]-> (posts)-[:HAS]->comments<-[:ADD]-(users)")
                    .Return(()=>Return.As<Post>("posts","comments","users"))
                    .Limit(50)
                    .Results.ToList();

我想从此查询创建一个Model，然后将此Model传递给View，以生成如下内容：

foreach(var post in Model.Posts)
{
  <div>@post.DateCreation</div>
  <div>@post.Author.FirstName</div>
  <div>@post.Content</div>
  foreach(var comment in post.Comments)
  {
      <div>@comment.Author.Name</div>
      <div>@comment.Content</div>
  }

}

我不知道如何从cypher查询返回一个适合上述foreach的模型。我必须做一个有帖子，评论列表的ViewModel？如何添加评论的用户？如何在C＃中查询？

在一个查询Neo4j C＃MVC5中获取帖子，评论和用户
