如何实现INotifyPropertyChanged来进行Xamarin绑定更新?i

public class MyClass : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }

    private string myProperty;
    public string MyProperty
    {
        get { return myProperty; }
        set
        {
            if (myProperty != value)
            {
                myProperty = value;
                OnPropertyChanged();
            }
        }
    }
}

MyClass myObject = new MyClass();
myObject.MyProperty = "Hello World";

Label myLabel = new Label();
myLabel.SetBinding(Label.TextProperty, new Binding("MyProperty"));
myLabel.BindingContext = myObject;
