1、创建ASP.NET MVC4 Web应用程序，选择WebAPI模板

 

2、添加silverlight项目

3、新建一个数据模型类，代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace NetMVCAPI.Models{    public class Contact    {        public int Id { get; set; }        public string Name { get; set; }        public string Gender { get; set; }    }}

4、新建一个控制器，代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Net;using System.Net.Http;using System.Web.Http;using NetMVCAPI.Models;namespace NetMVCAPI.Controllers{    public class ContactController : ApiController    {        Contact[] contacts = new Contact[]         {             new Contact(){ Id=1, Name="mk", Gender="男"},            new Contact(){ Id=2, Name="ll", Gender="男"},            new Contact(){ Id=3, Name="hj", Gender="男"},            new Contact(){ Id=4, Name="zxm", Gender="女"},            new Contact(){ Id=5, Name="wmq", Gender="女"},        };        /// <summary>        /// /api/Contact        /// </summary>        /// <returns></returns>        public IEnumerable<Contact> GetListAll()        {            return contacts;        }        /// <summary>        /// /api/Contact/id        /// </summary>        /// <param name="id"></param>        /// <returns></returns>        public Contact GetContactById(int id)        {            Contact contact = contacts.FirstOrDefault<Contact>(item => item.Id == id);            if (contact == null)            {                throw new HttpResponseException(HttpStatusCode.NotFound);            }            return contact;        }        /// <summary>        /// 根据性别查询        /// /api/Contact?Gender=女        /// </summary>        /// <param name="gender"></param>        /// <returns></returns>        public IEnumerable<Contact> GetListByGender(string gender)        {            return contacts.Where(item => item.Gender == gender);        }        /// <summary>        /// 根据姓名查询        /// /api/Contact/Name=mk        /// </summary>        /// <param name="name"></param>        /// <returns></returns>        public IEnumerable<Contact> GetListByName(string name)        {            return contacts.Where(item => item.Name == name);        }    }}

5、通过silverlight访问WebApi

using System;using System.Collections.Generic;using System.Linq;using System.Net;using System.Windows;using System.Windows.Controls;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Animation;using System.Windows.Shapes;namespace SilverlightApplication1{    public partial class MainPage : UserControl    {                public MainPage()        {            InitializeComponent();        }        private void Button_Click(object sender, RoutedEventArgs e)        {            var uriStr = new Uri(Application.Current.Host.Source, TextBoxUri.Text);            var wc = new WebClient();            wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(DownloadStringAsyncCompleted);            wc.DownloadStringAsync(uriStr);        }        void DownloadStringAsyncCompleted(object sender, DownloadStringCompletedEventArgs e)        {            try            {                TextBlock_Result.Text = e.Result;            }            catch (Exception ex)            {                TextBlock_Result.Text = ex.Message;            }        }    }}

6、运行如下：
