作为快速指南,您可以从以下课程开始:

public class AlarmDay : INotifyPropertyChanged
{
    public AlarmDay( string dayOfWeek )
    {
       DayOfWeek = dayOfWeek;       
    }

    public DayOfWeek { get; }

    private bool _isEnabled = false;
    public bool IsEnabled
    {
        get => _isEnabled;
        set
        {
           _isEnabled = value;
           NotifyPropertyChanged();
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;

    private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}
