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; });
        }
