Hola revisa el siguiente
link allí se muestra como consumir servicios WCF desde el cliente mendiante el uso de Jquery. Aunque también lo podrias hacer usando ASP.NET AJAX library y te resultaría más fácil.
Por ejemplo:
Tengo la siguiente ASPX.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="EjemploSerializacion.aspx.cs" Inherits="AJaxLib_RegClassInerz.EjemploSerializacion" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script type="text/javascript">
var ServiceProxy;
function pageLoad() {
ServiceProxy = new ServiceSample();
ServiceProxy.set_defaultSucceededCallback(ServiceCallSuccess);
ServiceProxy.set_defaultFailedCallback(OnErrorCallback);
}
function OnErrorCallback(error) {
alert(error._message);
}
function ServiceCallSuccess(result, userContext, methodName) {
var resultAJAX = document.all.Result;
if (result.length > 1 && typeof (result) != "string") {
for (var i = 0; i < result.length; i++) {
resultAJAX.innerHTML += result[i].FirstName + "<br/>";
}
}
else if (result.FirstName)
resultAJAX.innerHTML += result.FirstName +"<br/>";
else
resultAJAX.innerHTML += result + " form " + methodName + "<br/>";
}
function SayHello() {
var person = new AJaxLib_RegClassInerz.Person();
person.Id = 10;
person.FirstName = "Armando";
person.HappyDay = "\/Date(" + Date.parse("10/04/2010") + ")\/";
ServiceProxy.SayHello(person);
}
function GetPerson() {
ServiceProxy.GetPerson(3);
}
function GetPersons() {
ServiceProxy.GetPersons();
}
function GetPersonsByDateTiem() {
ServiceProxy.GetPersonsByDateTime("\/Date(" + Date.parse("01/04/1990") + ")\/", "\/Date(" + Date.parse("01/04/2010") + ")\/");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">

<div id="Result">

Tengo el siguiente servicio WCF
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.Text;
namespace AJaxLib_RegClassInerz
{
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ServiceSample
{
List<Person> persons = new List<Person>(){
new Person { Id = 1, FirstName = "Felipe", HappyDay = DateTime.Now.AddDays(-10000) },
new Person { Id = 2, FirstName = "Antonio", HappyDay = DateTime.Now.AddDays(-20000) },
new Person { Id = 3, FirstName = "Hernando", HappyDay = DateTime.Now.AddDays(-30000) },
new Person { Id = 4, FirstName = "Jose", HappyDay = DateTime.Now.AddDays(-40000) }};
// To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat is WebMessageFormat.Json)
// To create an operation that returns XML,
// add [WebGet(ResponseFormat=WebMessageFormat.Xml)],
// and include the following line in the operation body:
// WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";
[OperationContract]
public string SayHello(Person person) {
StringBuilder sb = new StringBuilder();
sb.Append("Hello " + person.FirstName);
TimeSpan ts = person.HappyDay - DateTime.Now;
sb.Append("\nYou have " + ts.Days / 365 + " years old");
sb.Append("\nYou're Id is " + person.Id);
return sb.ToString();
}
[OperationContract]
public List<Person> GetPersons()
{
return persons;
}
[OperationContract]
public Person GetPerson(int id = 1) {
var obj = persons.SingleOrDefault(p => p.Id == 1);
return obj;
}
[OperationContract]
public List<Person> GetPersonsByDateTime(DateTime dateTime1, DateTime dateTime2)
{
var pers = persons.Where(p => p.HappyDay >= dateTime1 && p.HappyDay <= dateTime2);
return pers.ToList();
}
// Add more operations here and mark them with [OperationContract]
}
[DataContract]
public class Person
{
int _id;
[DataMember]
public int Id
{
get { return _id; }
set { _id = value; }
}
string _firstName;
[DataMember]
public string FirstName
{
get { return _firstName; }
set { _firstName = value; }
}
DateTime _happyDay;
[DataMember]
public DateTime HappyDay
{
get { return _happyDay; }
set { _happyDay = value; }
}
}
}
Como verás allí la compatibilidad con ASP.NET ya te permite serializar los objetos tipo DataContract y objetern respuesta de los OperationContract de forma muy fácil y entendible.
