。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.);
        }
    }
