asp.net mvc - how to pass data from View to as an object Controller using ajax? -

i have search ajax request this:

  $.ajax({         type: 'post',         data: { firstname: firstname, lastname: lastname},         contenttype: "application/json; charset=utf-8",         url: 'getpeople',         datatype: 'json',        }     }); 

in getpeole action can parameter (firstname,lastname)

public virtual jsonresult getpeople(string firstname,string lastname)         {           ....         } 

if change ajax request

$.ajax({         type: 'post',         data: { firstname: firstname, lastname: lastname,age=age},         contenttype: "application/json; charset=utf-8",         url: 'getpeople',         datatype: 'json',        }     }); 

i must change getpeople

 public virtual jsonresult getpeople(string firstname,string lastname,int age)         {           ....         } 

i want searchparameters(firstname,lastname,age) object in getpeople

public virtual jsonresult getpeople(searchparam)     {         .....     } 

you declare class parameter so:

public class searchfilters {     public string firstname {get;set;}     public string lastname {get;set;}     public int age {get;set;} } 

and use in controller this:

public jsonresult getpeople(searchfilters filters) { } 

and in ajax post need pass data this:

data: json.stringify({ firstname: firstname, lastname: lastname,age=age})
