javascript - Sending complex object in ajax to MVC -

the value of list<order> returns null in controller action method while sending complex object. can identify issue? need pass array of objects indexes?

javascript

function oncustomerclick() {     //var orders = [];     //orders.push({ 'orderid': '1', 'orderby': 'saroj' });      var complexobject = {         firstname: 'saroj',         lastname: 'k',         //orders : orders         orders: [{ orderid: 1, orderby: 'saroj' }, { orderid: 2, orderby: 'kumar' }]     };      var obj = { customer: complexobject };     var data2send = json.stringify(obj);      $.ajax({         type: "post",         url: 'home/testcustomer1',         data: data2send,         contenttype: "application/json; charset=utf-8",         datatype: "json",         success: function (arg) { //call successfull         },         error: function (xhr) {             //error occurred         }     }); }; 

mvc

 public actionresult testcustomer1(customer customer)     {         return json(customer);     } 

c#

public class customer {     public string firstname { get; set; }     public string lastname { get; set; }     list<order> orders { get; set; } }  public class order {     public int orderid { get; set; }     public string  orderby { get; set; } } 

you need use public properties model binding. orders has no access modifier, private.

public class customer {     public string firstname { get; set; }     public string lastname { get; set; }     public list<order> orders { get; set; } // <---- } 

other that, looks fine.
