在很多地方需要用上INotifyPropertyChanged的接口，MVVM模式，List等集合都会用到。

通常我们使用

protected void OnChange(PropertyChangedEventArgs args) => PropertyChanged?.Invoke(this, args);        private OutString _Text;        public OutString Text        {            get => _Text;            set            {                _Text = value;                OnChange(new PropertyChangedEventArgs("Text"));            }        }

 

 

不过可以 使用特性来减少代码量

CallerMemberName可以代替手工输入名称

 

public class Test:INotifyPropertyChanged    {        protected void OnPropertyChanged([CallerMemberName] string name="")        {            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));        }        private BitmapImage i;        public BitmapImage Image { get=>i; set { i = value; OnPropertyChanged(); } }        public event PropertyChangedEventHandler PropertyChanged;    }
