c#类的继承与包含的关系

基础例子

class Dept
{
private string name;
private Emp emp;

public string getName()
{
return this.name;
}

public void setName(string name)
{
this.name = name;
}

public Emp getEmp()
{
return this.emp;
}

public void setEmp(Emp emp)
{
this.emp = emp;
}

}

class Emp
{
private string name;
private string six;
private double tel;
private Auth auth;

public string getName()
{
return this.name;
}

public void setName(string name)
{
this.name = name;
}

public string getsix()
{
return this.six;
}
public void setSix(string six)
{
this.six = six;
}

public void setTel(double tel)
{
this.tel = tel;
}
public double getTel()
{
return this.tel;
}

public void setAuth(Auth auth)
{
this.auth = auth;
}

public Auth getAuth()
{
return this.auth;
}

}

class Auth
{
private int x;
private int y;

public void setX(int x)
{
this.x = x;
}

public int getX()
{
return this.x;
}

public void setY(int y)
{
this.y = y;
}

public int getY()
{
return this.y;
}
}

class Program
{

static void Main(string[] args)
{
//哪个部门里的哪个人有哪些权限

Auth auth1 = new Auth();

auth1.setX(1);

Auth auth2 = new Auth();
auth1.setX(1);
auth2.setY(2);

Emp zhangsan = new Emp();
