SilverLight中数据与通信之ASMX

SilverLight中数据与通信之ASMX

1.       新建一个Web服务文件 Blogservice.asmx

public class Blogservice : Webservice

    {

        [WebMethod]

        public Post[] GetPosts()

        {

            List<Post> posts = new List<Post>()

        {

            new Post{ Id=1,title="一步一步学Silverlight 2系列（13）：数据与通信之Webrequest",Author="TerryLee" },

            new Post{ Id=2,title="一步一步学Silverlight 2系列（12）：数据与通信之WebClient",

            new Post{ Id=3,title="一步一步学Silverlight 2系列（11）：数据绑定",

            new Post{ Id=4,title="一步一步学Silverlight 2系列（10）：使用用户控件",

            new Post{ Id=5,title="一步一步学Silverlight 2系列（9）：使用控件模板",

            new Post{ Id=6,title="一步一步学Silverlight 2系列（8）：使用样式封装控件观感",Author="TerryLee" }

        };

            return posts.ToArray();

        }

    }

    public class Post

    {

        public int Id { get; set; }

        public String title { get; set; }

        public String Author { get; set; }

}

2.      调用

前台代码：

   <ListBox x:Name="Posts" Grid.Row="1" Margin="40 10 10 10">

            <ListBox.ItemTemplate>

                <DataTemplate>

                    <StackPanel Orientation="Horizontal">

                        <TextBlock Text="{Binding Id}" Height="40" Foreground="Red"></TextBlock>

                        <TextBlock Text="{Binding title}" Height="40"></TextBlock>

                        <TextBlock Text="{Binding Author}" Height="40" Foreground="Orange"></TextBlock>

                    </StackPanel>

                </DataTemplate>

            </ListBox.ItemTemplate>

        </ListBox>

后台代码：

Loaded+=new RoutedEventHandler(MainPage_Loaded);

  private void MainPage_Loaded(object sender,RoutedEventArgs E)

        {

            BlogserviceSoapClient client = new BlogserviceSoapClient();

            client.GetPostsCompleted += new EventHandler<GetPostsCompletedEventArgs>(client_GetPostsCompleted);

            client.GetPostsAsync();

        }

        void client_GetPostsCompleted(object sender,GetPostsCompletedEventArgs E)

        {

            if (e.Error == null)

            {

                Posts.Itemssource = e.Result;

            }

}
