首先,您需要一个好的库来帮助您将 json 字符串转换为 c# 模型表示(反序列化)。
您可以编写自己的,使用内置的平台反序列化器或只使用 NewtonSoft.json
要为 WP 安装 NewtonSoft,请使用 Nuget。请注意,您必须使用 5.0.8 版本,因为 6.x 系列不支持 Windows Phone 7。
我已经稍微简化了您的 json 字符串,不明白为什么国家/地区属性会包含国家/地区列表?
c#,在你的代码后面
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
//BindCountries();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
BindCountries();
}
private void BindCountries()
{
var json =
"{\"type\":\"ok\",\"countries\":[{\"title\":\"Country-1\",\"description\":\"US\",\"status\":\"1\"},{\"title\":\"Country-2\",\"description\":\"Australia\",\"status\":\"0\"},{\"title\":\"Country-3\",\"description\":\"Brazil\",\"status\":\"0\"}]}";
var countryResult = JsonConvert.DeserializeObject<CountryResult>(json);
if (countryResult.Type.Equals("ok", StringComparison.InvariantCultureIgnoreCase))
{
lstCountries.ItemsSource = countryResult.Countries;
}
}
}
public class CountryResult
{
public string Type { get; set; }
public IEnumerable<Country> Countries { get; set; }
}
public class Country
{
public string Title { get; set; }
public string Description { get; set; }
public int Status { get; set; }
}
xml:
