c#中编的牌类游戏中的问题

Question

public Card(Suit suit, FaceValue faceVal, bool isCardUp)        {            this.suit = suit;            this.faceVal = faceVal;            this.isCardUp = isCardUp;        }        /// <summary>        /// Return the card as a string (i.e. "The Ace of Spades")        /// </summary>        /// <returns></returns>        public override string ToString()        {            return "The" + faceVal.ToString() + "of" + suit.ToString();        }最后那句什么意思啊？没见过这种用法啊？

Answer 1

重载ToString()函数。就是当你调Card.ToString()的时候输出自定义的字符串
