How to convert JSON data to Class Object

JS Code.

// this is person class constructor. function personClass(id, name, address, phone) { this.Id = id; this.Name = name; this.Address = address; this.Phone = phone; } var person = new Array(); person.push(new personClass("101", $('#txtName').val(), $('#txtAddress').val(), $('#txtPhone').val()); AjaxRequest = function ("PersonInfo.asmx/AddNewPerson", "{'person[]':'" + JSON.stringify(person) + "'}", successcallback, errorcallback) { $.ajax({ type: "POST", url: url, data: param, contentType: "application/json; charset=utf-8", dataType: "json", success: successcallback, error: errorcallback }); } 

C# Code.

[ScriptMethod(ResponseFormat = ResponseFormat.Json)] [WebMethod(EnableSession = true)] public string AddProduct(Person[] person) { return person[0].Id; } public class Person { private string _id = String.Empty; private string Id { get { return _id; } set { _id = value; } } private string _name = String.Empty; private string Name { get { return _name; } set { _name = value; } } private string _address = String.Empty; private string Address { get { return _address; } set { _address = value; } } private string _phone = String.Empty; private string Id { get { return _phone; } set { _phone = value; } } } 

Problem is that : show response error message following -:

{"Message":"Invalid web service call, missing value for parameter: \u0027person\u0027.","StackTrace":" at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary2 parameters)\r\n at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

Please suggest the solution.
