。net用lamda实现属性的优雅操作

  internal class ExtensionObjectURL
     {
         internal string name { get; set; }
     }
     internal static class Extension
     {
         internal static void NotifycationPropertyChanged<T, TProperty>(this T propertyChangedBase, Expression<Func<T, TProperty>> expression)
         {
             var body = expression.Body as MemberExpression;
             if (body != null)
             {
                 var propertyName = body.Member.Name;
                 // 做点神马呗
                 return;
             }
             throw new InvalidOperationException("指定的expression无效,expression必须是对象的（属性,字段）成员的访问表达式。");
         }

         internal void ss()
         {
             var s = new ExtensionObjectURL();
             s.NotifycationPropertyChanged(p => p.);
         }
     }
