如何让xamarin自定义控件中的两个可绑定属性相互识别？

public class CustomControl : View
{
    public static readonly BindableProperty TextProperty =
        BindableProperty.Create(nameof(Text), typeof(string), typeof(CustomControl), string.Empty);

    public static readonly BindableProperty BackgroundColorProperty =
        BindableProperty.Create(nameof(BackgroundColor), typeof(Color), typeof(CustomControl), Color.Default);

    public string Text
    {
        get { return (string)GetValue(TextProperty); }
        set { SetValue(TextProperty, value); }
    }

    public Color BackgroundColor
    {
        get { return (Color)GetValue(BackgroundColorProperty); }
        set { SetValue(BackgroundColorProperty, value); }
    }
}
