如何在XAML中的类中指定ViewModel类

我有一些XAML

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:model="clr-namespace:SmartCubeMobile;assembly=XFMultiPicker"
             xmlns:xfMultiPicker="clr-namespace:XFMultiPicker;assembly=XFMultiPicker"
             x:Class="XFMultiPicker.MainPage">

    <StackLayout>
        <xfMultiPicker:MultiPickerView x:TypeArguments="model:AddressItem1"
                                       ItemsSource="{Binding AvailableItems}"
                                       SelectedItems="{Binding SelectedItems}"/>
    </StackLayout>
</ContentPage>

如何将XAML x:TypeArguments行修改为“指向”AddressItem2？似乎什么都不起作用，例如“model:FinanceViewModel.AddressItem2”与其他所有内容一样失败。有人有什么想法吗？提前感谢您提出的任何建议

找到解决方法-不再需要这些废话了

namespace SmartCubeMobile
{
    public class AddressItem1
    {
        internal string Text { get; set; }
    }

    public class FinanceViewModel : INotifyPropertyChanged
    {
        public class AddressItem2
        {
            internal string Text { get; set; }
        }
    }
}
