【C#】Struct vs Class

Struct就像是轻量版本的Class~ 但它们间还是有几点差异性~

我们今天就来看看Struct跟Class的差异性吧~

学习目标: Struct and Class的概念及实务

学习难度: ☆☆☆

Struct在以下情形时使用是一个不错的选择~

• Struct表示单一值~ 例如~ 位置 ~

• Struct中的值尽量是不可变~

• Struct尽量不要频繁装箱~ 拆箱~

Struct实例 ~

    struct Location
    {
        public int x, y;
        public Location(int x, int y)
        {
            this.x = x;
            this.y = y;
        }
    }

    public class MainProgram
    {
        static void Main()
        {
            Location location = new Location(100,200);

            Console.WriteLine(location.x+","+location.y);
        }
    }

Class实例 ~

    class Shop
    {
        public string name;

        public int x, y;

        public Shop(int x, int y,string name)
        {
            this.x = x;
            
            this.y = y;
            
            this.name = name;
        }
    }

    public class MainProgram
    {
        static void Main()
        {
            Shop shop = new Shop(150,300,"KFC");

            Console.WriteLine(shop.x+","+ shop.y+ ","+shop.name);
        }
    }
