C# 在CarrouselView中获取抽头元素的索引

我正在学习Xamarin，我想在我的CarouselView中获取被点击元素的idex

以下是Xaml代码：

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
  x:Name="currentPage">

<StackLayout >

<CarouselView x:Name="TestList"  >
        <CarouselView.ItemTemplate >
            <DataTemplate>

        <StackLayout >


                <StackLayout Grid.Row="3"  VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">


                    <StackLayout.GestureRecognizers>
                        <TapGestureRecognizer Command="{Binding CarouselItemTapped,Source={x:Reference currentPage}}" CommandParameter="{Binding .}"/>
                    </StackLayout.GestureRecognizers>

                </StackLayout>


        </StackLayout>

            </DataTemplate>
        </CarouselView.ItemTemplate>
    </CarouselView>
</StackLayout>

属性将告诉您可见项的索引，并且是实际项。

让我们假设

ListWordsTest

是您的旋转木马视图的项源，然后我们可以通过以下方式获取索引：

CarouselItemTapped = new Xamarin.Forms.Command((selectItem) => 
{

    var mynews = selectItem; //as IDoNotKnow  I would like to get the item index 

    var index = ListWordsTest.IndexOf((TestModel)selectItem);
});
