C# 操做符重载

两个自定义的类别，一般不容许相加，不过咱们能够重载+号操做符来方便其相加

 class Program
    {
        static void Main(string[] args)
        {
            A a = new A();
            a.x = 1;
            B b = new B();
            b.y = 2;
            A c = a + b;//由于重载了加号操做符，因此这里能够直接相加
            Console.WriteLine(c.x);//4
          
            Console.Read();
        }
        public class A
        {
            public int x;
            public static A operator +(A a, B b)
            {
                a.x = a.x + b.y;
                return a;
            }
        }
        public class B
        {
            public int y;
        }
    }

 

 若是须要还能够重载其余操做符如乘号等
