C#运算符笔记

C# 原来也可以进行向量运算，这里解决了一个为时已久的疑惑。

operator

 struct Vector
    {
        public double x, y, z;

        public Vector(double x, double y, double z)
        {
            this.x = x;
            this.y = y;
            this.z = z;
        }

        public Vector(Vector rhs)
        {
            this.x = rhs.x;
            this.y = rhs.y;
            this.z = rhs.z;
        }

        public override string ToString()
        {
            return "(" + x + "," + y + "," + z + ")";
        }

        public static Vector operator +(Vector lhs, Vector rhs)
        {
            Vector result = new Vector(lhs);
            result.x += rhs.x;
            result.y += rhs.y;
            result.z += rhs.z;
            return result;
        }
        public static Vector operator *(Vector lhs, Vector rhs)
        {
            Vector result = new Vector(lhs);
            result.x *= rhs.x;
            result.y *= rhs.y;
            result.z *= rhs.z;
            return result;
        }
    }

  Vector vect1, vect2, vect3,vect4;
            vect1 = new Vector(3.0, 3.0, 1.0);
            vect2 = new Vector(2.0, -4.0, -4.0);
            vect3 = vect1 + vect2;
            vect4 = vect1 * vect2;
            Console.WriteLine("vect1=" + vect1.ToString());
            Console.WriteLine("vect2=" + vect2.ToString());
            Console.WriteLine("vect3=" + vect3.ToString());
            Console.WriteLine("vect4=" + vect4.ToString());
