silverlight中使用Bing搜索

很多大型网站提供了对外的接口，比如Bing，这样我们就可以在我们的使用Bing的API来使用搜索功能。

  首先我们需要一个Bing appID 来使用Bing 的API,在http://www.bing.com/developers/createapp.aspx可以获得Bing appID .

给Silverlight项目中添加Service References: http://api.search.live.net/search.wsdl?AppID=******.

XAML:

    <Grid x:Name="LayoutRoot">
        <Grid.RowDefinitions>
            <RowDefinition Height="100"></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
        </Grid.RowDefinitions>
        <StackPanel Orientation="Horizontal">
            <Image x:Name="BingLogoImage" Source="binglogo.png" Width="100" Stretch="Uniform" Margin="3" VerticalAlignment="Center"></Image>
            <TextBox x:Name="SearchTextBox" Width="150" Margin="3" VerticalAlignment="Center" ></TextBox>
            <Button x:Name="SearchButton" Click="SearchButton_Click" Content="Search!" HorizontalAlignment="Center" VerticalAlignment="Center"></Button>
        </StackPanel>
        <ListBox x:Name="ResultListBox" Grid.Row="1" Margin="3">
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                        </Grid.RowDefinitions>
                        <TextBlock Text="{Binding Title}" FontWeight="Bold" FontSize="15" TextDecorations="Underline" Foreground="#007fc6"></TextBlock>
                        <TextBlock Text="{Binding Description}" Grid.Row="1" TextWrapping="Wrap" Width="400" HorizontalAlignment="Left"></TextBlock>
                        <TextBlock Text="{Binding Uri}" Grid.Row="2" Foreground="#568e71"></TextBlock>
                    </Grid>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>
    </Grid>

 

  XAML.cs

        private void SearchButton_Click(object sender, RoutedEventArgs e)
        {
            BingService.LiveSearchPortTypeClient soapClient = new SilverBing.BingService.LiveSearchPortTypeClient();
            SearchRequest request = new SearchRequest();
            request.AppId = "61691gyt195F23456469594BAA33450A99CF3522";
            request.Sources = new SourceType[] { SourceType.Web };

            if (SearchTextBox.Text != string.Empty)
            {
                request.Query = SearchTextBox.Text;
                soapClient.SearchCompleted += new                                               EventHandler<SearchCompletedEventArgs>(soapClient_SearchCompleted);
                soapClient.SearchAsync(request);
            }
        }

        void soapClient_SearchCompleted(object sender, SearchCompletedEventArgs e)
        {
            SearchResponse response = e.Result;
            if (response.Web.Results.Count() > 0)
            {
                var results = from result in response.Web.Results
                              select new BingSearchResult 
                              { 
                                  Title = result.Title, 
                                  Uri = result.Url, 
                                  Description = result.Description 
                              };
                ResultListBox.ItemsSource = results.ToList();
            }
        }

 

 

  结果如下：
