怎么实现运算符的重载？

1.在类中或者结构中用operator 关键字来声明运算符
2.所有的运算符重载都声明为public (公开的)和static(静态的)

最好有代码的事例

1. class Program
   
2.      {
   
3.          static void Main(string[] args)
   
4.           {
   
5.               Vector vect1, vect2, vect3;
   
6.              vect1 = new Vector(3.0, 3.0, 1.0);
   
7.               vect2 = new Vector(2.0, -4.0, -4.0);
   
8. vect3 = vect1 + vect2;
   
9. 
   
10. Console.WriteLine("vect1=" + vect1.ToString());
    
11. Console.WriteLine("vect2=" + vect2.ToString());
    
12. Console.WriteLine("vect3=" + vect3.ToString());
    
13. Console.ReadLine();
    
14. }
    
15. }
    
16. 
    
17. struct Vector
    
18. {
    
19. public double x, y, z;
    
20. 
    
21. public Vector(double x, double y, double z)
    
22. {
    
23. this.x = x;
    
24. this.y = y;
    
25. this.z = z;
    
26. }
    
27. 
    
28. public Vector(Vector rhs)
    
29. 
    
30. {
    
31. this.x = rhs.x;
    
32. this.y = rhs.y;
    
33. this.z = rhs.z;
    
34. }
    
35. 
    
36. public override string ToString()
    
37. {
    
38. return "(" + x + "," + y + "," + z + ")";
    
39. }
    
40. 
    
41. public static Vector operator +(Vector lhs, Vector rhs)
    
42. {
    
43. Vector result = new Vector(lhs);
    
44. result.x += rhs.x;
    
45. result.y += rhs.y;
    
46. result.z += rhs.z;
    
47. return result;
    
48. }
    
49. }
