您必须在 XAML 中准备 UI 并从代码隐藏设置数据绑定。

示例 xml 代码：

<ListBox Name="ListBoxNews" Margin="10,0,30,0" Height="486" Width="404" FontSize="20">
            <ListBox.ItemTemplate>
                <DataTemplate >
                    <StackPanel Margin="10,0,10,8">
                        <TextBlock Text="{Binding news_date}" TextWrapping="Wrap" FontSize="18" />
                        <TextBlock Text="{Binding news_title}" TextWrapping="Wrap" FontSize="24" /> 
                    </StackPanel>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

以及来自代码隐藏的数据绑定。

void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        var rootObject = JsonConvert.DeserializeObject<List<Contacts>>(e.Result);
        ListBoxNews.ItemsSource = rootObject;
    }

试试这个，问我你是否还有疑问。
