如何在Xamarin表单(XAML)上添加像android:id这样的android属性？

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="YourNamespace.YourPage">

    <StackLayout>
        <Label x:Name="myLabel" Text="Hello Xamarin Forms!" />
        <Button Text="Click Me" Clicked="Button_Clicked" />
    </StackLayout>

</ContentPage>

namespace YourNamespace
{
    public partial class YourPage : ContentPage
    {
        public YourPage()
        {
            InitializeComponent();
        }

        private void Button_Clicked(object sender, EventArgs e)
        {
            myLabel.Text = "Button Clicked!";
        }
    }
}
