c# - domaintools json deserialize? -

i'm using asp.net mvc4 , json.net

and have json structure http://api.domaintools.com/v1/domaintools.com/whois/

how can deserialize own class ? looks bit complicated structure me realize how build class ?

i've tried far:

 var json = "{\"response\":{\"registrant\":\"domaintools, llc\",\"registration\":{\"created\":\"1998-08-02\",\"expires\":\"2014-08-01\",\"updated\":\"2010-08-31\",\"registrar\":\"cheap-registrar.com\",\"statuses\":[\"ok\"]},\"name_servers\":[\"ns1.p09.dynect.net\",\"ns2.p09.dynect.net\",\"ns3.p09.dynect.net\",\"ns4.p09.dynect.net\"],\"whois\":{\"date\":\"2013-05-12\",\"record\":\"domain name: domaintools.com\\n\\nregistrant contact:\\n   domaintools, llc\\n   domain administrator (memberservices@domaintools.com)\\n   +1.2068389035\\n   fax: +1.2068389056\\n   2211 5th avenue\\n   suite 201\\n   seattle, wa 98121\\n   us\\n\\nadministrative contact:\\n   domaintools, llc\\n   domain administrator (memberservices@domaintools.com)\\n   +1.2068389035\\n   fax: +1.2068389056\\n   2211 5th avenue\\n   suite 201\\n   seattle, wa 98121\\n   us\\n\\ntechnical contact:\\n   domaintools, llc\\n   domain administrator (memberservices@domaintools.com)\\n   +1.2068389035\\n   fax: +1.2068389056\\n   2211 5th avenue\\n   suite 201\\n   seattle, wa 98121\\n   us\\n\\n   status: active\\n   creation date: 13-jul-2002\\n   expiration date: 13-jul-2016\\n   name server: ns1.p09.dynect.net\\n   name server: ns2.p09.dynect.net\\n   name server: ns3.p09.dynect.net\\n   name server: ns4.p09.dynect.net\\n\"}}}";  public class response     {         public string registrant { get; set; }         public registration registration { get; set; }         public list<string> name_servers { get; set; }         public whois whois { get; set; }     }     public class registration     {         public datetime created { get; set; }         public datetime expires { get; set; }         public datetime updated { get; set; }         public string registrar { get; set; }         public list<string> statuses { get; set; }       }     public class whois     {         public datetime date { get; set; }         public string record { get; set; }      }  var response = jsonconvert.deserializeobject<response>(json);  >> null 

it start http://json2csharp.com/ site find right structure, example gives:

public class registration {     public string created { get; set; }     public string expires { get; set; }     public string updated { get; set; }     public string registrar { get; set; }     public list<string> statuses { get; set; } }  public class whois {     public string date { get; set; }     public string record { get; set; } }  public class response {     public string registrant { get; set; }     public registration registration { get; set; }     public list<string> name_servers { get; set; }     public whois whois { get; set; } }  public class rootobject {     public response response { get; set; } } 

you need use rootobject class want deserialize:

var response = jsonconvert.deserializeobject<rootobject>(json);
