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());

输出：
