值不在Windows应用商店应用程序的预期范围内

我的xaml代码如下:

        </ListView>

    </Grid>

我使用以下代码将JSON数据加载到web:

public OrderListing()
{
    this.InitializeComponent();
    this.navigationHelper = new NavigationHelper(this);
    this.navigationHelper.LoadState += navigationHelper_LoadState;
    this.navigationHelper.SaveState += navigationHelper_SaveState;
    loadData1();
}

private async void loadData1()
{
    HttpClient http = new HttpClient();

    var response = await http.GetStringAsync("http://10.0.40.117/" + "rest/admin/order/list.json");

    var orderData = JsonConvert.DeserializeObject<OrderRootClass>(response);

    OrderListView.ItemsSource = orderData;
}

这是订单根类:

public class OrderRootClass
{
    public Order[] orders { get; set; }

}

它给出了错误。我找到了一些关于这个的帖子,但这没有帮助。
