我有json代码：

{
responses:
[{
photo:[{url:"YYYY"},{url:"YYYY"}]
},
{
photo:[{url:"XXXX"},{url:"XXXX"}]
}]
}

在我的应用程序中，我试图解析每个响应中的响应和照片。我尝试在主gridview 中使用gridview，但它不起作用。有什么方法可以实现吗？谢谢您的帮助！

HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync("ЧЧЧЧЧ");

string Text = await response.Content.ReadAsStringAsync();

List<RootObject> values = JsonConvert.DeserializeObject<List<RootObject>>(Text);
lvMain3.ItemsSource = values;
cvsMain.Source = values[0].trends;

public class Trend
{
    public string Query { get; set; }
    public string Name { get; set; }
    private UIElement _control = new MyUserControl1();
    public UIElement Control { get { return _control; } }
}

public class Location
{
    public string Name { get; set; }
    public int Woeid { get; set; }
}

public class RootObject
{
    public string As_of { get; set; }
    public List<Trend> trends { get; set; }
    public string created_at { get; set; }
    public List<Location> Locations { get; set; }
}

还有我将gridview放在主gridview中的xaml代码：

<Page.Resources>
    <CollectionViewSource x:Name="cvsMain" ItemsPath="Persons"/>
</Page.Resources>
.... 
<GridView x:Name="lvMain3">
    <GridView.ItemTemplate>
        <DataTemplate>
            <Grid Height="410" Width="410" Background="Gray">
                <GridView x:Name="lvMain4">
                    <GridView.ItemTemplate>
                        <DataTemplate>
                            <Grid Height="410" Width="410" Background="Gray">
                                <TextBlock Text="{Binding Name}"/>
                            </Grid>
                        </DataTemplate>
                    </GridView.ItemTemplate>
                </GridView>
            </Grid>
        </DataTemplate>
    </GridView.ItemTemplate>
</GridView>

实际的 JSON：

 [
   {
      "as_of":"2012-08-31T15:31:55Z",
      "trends":[
         {
            "query":"%23GDTHATXX",
            "name":"#GDTHATXX",
            "promoted_content":null,
            "url":"http:\/\/twitter.com\/search\/?q=%23GDTHATXX",
            "events":null
         },
         {
            "query":"%23UnMundoEnElQue",
            "name":"#UnMundoEnElQue",
            "promoted_content":null,
            "url":"http:\/\/twitter.com\/search\/?q=%23UnMundoEnElQue",
            "events":null
         }
      ]
   },
 {
      "as_of":"2012-08-31T15:31:55Z",
      "trends":[
         {
            "query":"%23GDTHATXX",
            "name":"#GDTHATXX",
            "promoted_content":null,
            "url":"http:\/\/twitter.com\/search\/?q=%23GDTHATXX",
            "events":null
         },
         {
            "query":"%23UnMundoEnElQue",
            "name":"#UnMundoEnElQue",
            "promoted_content":null,
            "url":"http:\/\/twitter.com\/search\/?q=%23UnMundoEnElQue",
            "events":null
         }
      ]
   }
]
