关键代码：

        /// <summary>        /// 利用反射来判断对象是否包含某个属性        /// </summary>        /// <param name="instance">object</param>        /// <param name="propertyName">需要判断的属性</param>        /// <returns>是否包含</returns>        public static bool ContainProperty(this object instance, string propertyName)        {            if (instance != null && !string.IsNullOrEmpty(propertyName))            {                PropertyInfo _findedPropertyInfo = instance.GetType().GetProperty(propertyName);                return (_findedPropertyInfo != null);            }            return false;        }

代码使用：

            bool cc = _person.ContainProperty("cc");            bool aa = _person.ContainProperty("Age");
