1、创建ASP.NET MVC4 Web应用程序，选择WebAPI模板

2、添加silverlight项目

bubuko.com,布布扣

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;
            }
        }
    }
}
