Question

我在我的项目上尝试CarouselView。但是当我运行我的项目时，我收到了这个错误。

这是我的xaml代码;

<?xml version="1.0" encoding="UTF-8"?>
<base:HotelDetailPageXaml
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="XamarinCRM.Pages.Hotels.HotelDetailPage"
xmlns:statics="clr-namespace:XamarinCRM.Statics"
xmlns:base="clr-namespace:XamarinCRM.Pages.Hotels"
xmlns:hotelViews="clr-namespace:XamarinCRM.Views.Hotels"
xmlns:i18n="clr-namespace:XamarinCRM.Localization"
xmlns:cv="clr-namespace:Xamarin.Forms;assembly=Xamarin.Forms.CarouselView"
    Title="{Binding Hotel.Name}">
  <base:HotelDetailPageXaml.Content>
        <StackLayout Spacing="0">          
          <cv:CarouselView ItemsSource="{Binding Hotel.HotelImages}">
            <cv:CarouselView.ItemTemplate>
              <DataTemplate>
                <StackLayout HeightRequest="200">
                  <Image HeightRequest="200" Aspect="AspectFill" Source="{Binding FullPath}"/>
                </StackLayout>
              </DataTemplate>
            </cv:CarouselView.ItemTemplate>
          </cv:CarouselView>
  </StackLayout>
  </base:HotelDetailPageXaml.Content>
</base:HotelDetailPageXaml>

这是我叫json服务;

 public async Task<IEnumerable<HotelModel>> GetHotelsAsync(bool includeLeads = false)
        {
            string path = "my service url";
            HttpClient Client = new HttpClient();
            var task = await Client.GetAsync(path);
            var jsonString = await task.Content.ReadAsStringAsync();
            List<HotelModel> hotelList = new List<HotelModel>();
            List<HotelImageModel> hotelImageList = new List<HotelImageModel>();
            dynamic json = JsonConvert.DeserializeObject(jsonString);   

                        for (int j = 0; j < 10; j++)
                        {
                            HotelImageModel hotelImage = new HotelImageModel();    
                            hotelImage.FullPath = json["data"][i]["HotelImages"][j]["FullPath"].Value;    
                            hotel.HotelImages.Add(hotelImage);
                        }
                    }

我是酒店的索引号，而j是酒店的图像索引号
