【C#】实现INotifyPropertyChanged的3种方法

 class StudentItemViewModel:INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;
 
        public Student Student { get; set; }
 
        private bool _isSelected;
        public bool IsSelected
        {
            get { return _isSelected; }
            set
            {
                _isSelected = value;
                this.PropertyChanged(this,new PropertyChangedEventArgs("IsSelected"));
                //NotifyPropertyChanged("IsSelected");
            }
        }
 
        private void NotifyPropertyChanged(string Name)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(Name));
            }
        }
 
    }
 
    class NotifyCationObject : INotifyPropertyChanged
    {
        private string GetPropertyName<T>(Expression<Func<T>> action)
        {
            var expression = (MemberExpression)action.Body;
            return expression.Member.Name;
        }
 
        protected void NotifyPropertyChanged<T>(Expression<Func<T>> action)
        {
            string name = GetPropertyName<T>(action);
            NotifyPropertyChanged(name);
        }
 
        private event PropertyChangedEventHandler PropertyChanged;
 
        private void NotifyPropertyChanged(string Name)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(Name));
            }
        }
    }
