代码如下:
namespace x{
public class A{
public string sayHello(){
/*
当classs B的实例调用class A的这个方法时
我如何在此处获取classs B的实例的句柄并
能classs B的实例的方法Add()进行调用
*/
return "hello evey one";
}
}
}
namespace y{
using x;
public class B{
int _n;
public int n{
get{return _n;}
set{_n=value;}
}
public int Add(){
return ++n;
}
static void Main(){
A a=new A();
string xx=a.sayHello();
}
}
}
哪位兄弟知道,请指点一二
