c# - Exclude certain fields when returning as json -

i have asp.net web api application.

for lets application consists of user entity , post entity. post written user, every post entity contains reference user entity.

class post {      public int id { get; set; }      public string title  { get; set; }      public string content { get; set; }      public user user { get; set; } // reference user wrote post }  

the problem when want return list of posts json. don't want include writers of posts inside list, in other words, want exclude user field list of posts.

example:

[     {         "id": 1,         "title": "post a",         "content": "..."     },     {         "id": 2,         "title": "post b",         "content": "..."     } ] 

i know can creating new class called jsonpost without user field , converting list of post's list of jsonpost's linq, want solve without creating new class.

thanks, arik

just mark post's user property [jsonignore] attribute newtonsoft.json namespace , won't serialized

using newtonsoft.json; class post {      public int id { get; set; }      public string title  { get; set; }      public string content { get; set; }      [jsonignore]     public user user { get; set; } // property won't serialized }
