silverlight调用MVC WebApi方法

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：
