WPF 实现INotifyPropertyChanged .Net Framework 4.5

　　自己动手写了一个基类来实现INotifyPropertyChanged接口，以后可以直接使用。

 using System.ComponentModel;
 using System.Runtime.CompilerServices;

 public abstract class NotifyPropertyBase: INotifyPropertyChanged
 {
      public event PropertyChangedEventHandler PropertyChenged;

      protected void SetProperty<T>(ref T storage, T value, [CallerMemberName] string propertyName = null)
      {
           if (object.Equals(storage, value)) return;
           storage = value;
           this.OnPropertyChanged(propertyName);
      }

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