得到下面 此错误试图有关系,即表示1周后可以有多个postComments循环引用检测的LINQ
在序列化类型System.Collections.Generic.List的目的时检测到循环引用`1 [[DAO.Models.PostComment,DAO,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = null]]'。
int userId = (int)Session["UserId"];
try
{
IEnumerable<Post> userPosts;
userPosts = (from q in db.Posts
where q.UserId == userId
&& q.PostId > postid
select q).Take(5).ToList();
return Json(userPosts.Select(x => new
{
success = 1,
contenttext = x.PostContent,
postId = x.PostId,
comments = x.PostComments
}), JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
return Json(new { success = 0 });
}
finally
{
//db.Dispose();
}
我Post类
public partial class Post
{
public Post()
{
this.PostComments = new List<PostComment>();
}
public int UserId { get; set; }
public int PostId { get; set; }
public string PostContent { get; set; }
public virtual ICollection<PostComment> PostComments { get; set; }
public partial class PostComment
{
public long PostCommentID { get; set; }
public int PostId { get; set; }
public int ParentCommentID { get; set; }
public System.DateTime CommentDate { get; set; }
public string Comment { get; set; }
public virtual Post Post { get; set; }
}
}
你有没有在将它串行化之前将它转换成匿名类的代码片段? – 2013-03-22 01:28:22
var y =来自p中的db.Posts select new {PostID = p.PostID,Comments = p.Comments} – cherhan 2013-03-22 01:33:12
