之前听老师讲过一元运算符和二元运算符，现在看着例子看都看不懂了啊，不知道它这里面的实例对象里面的实例成员变量是怎样相加的，顺序有点模糊，求指教
 public class myClass{
           public int a,b;
           public myClass(int aa, int bb){
               this.a = aa;
                    this.b = bb;
           }
           public static myClass operator ++(myClass obj){
              obj.a++;
              obj.b++;
              return obj;
           }
           public static void Main(string[] args){
        myClass myObj=new myClass(34,-54);
          myObj++;
        Console.WriteLine(myObj.a);
        Console.WriteLine(myObj.b);
        Console.ReadLine();
           }
     }

谢谢，今天做了几道例题懂了
