List中的find的两种用法

        /// <summary>        /// 查找乘客信息        /// </summary>        /// <param name="name">乘客名称</param>        /// <returns>Passenger</returns>        public static Passenger GetPassengerByName(string name) {            return PassengerArry.Find(delegate(Passenger p) {                return p.Passenger_name == name;            });        }        /// <summary>        /// 查找乘客信息        /// </summary>        /// <param name="name">乘客名称</param>        /// <returns>Passenger</returns>        public static Passenger GetPassengerByName(string idCard)        {            return PassengerArry.Find((p) => { return p.PassengerIdNo == idCard; });        }
