Developer 被 Manager 所管理。（共 30 分）(一) 請劃出程式碼中組織樹狀圖，並說明之：（7 分)
abstract class Employee {
public abstract void add(Employee employee);
public abstract void remove(Employee employee);
public abstract void myPrint();
public virtual void setDep(int dep) { this.dep = dep; }
public void print() {
Console.WriteLine(dep + ":" + Name + ", Salary = " + Salary);
myPrint();
}
public String Name { get; set; }
public int Salary { get; set; }
protected int dep;
private String name;
private int salary;
}
class Manager: Employee {
public Manager(String name, int salary) {
Name = name;
Salary = salary;
setDep(1);
}
public override void setDep(int dep) {
this.dep = dep;
foreach (Employee employee in employees) {
employee.setDep(this.dep + 1);
}
}
public override void add(Employee employee) {
employee.setDep(dep + 1);
employees.Add(employee);
}
public override void myPrint() {

Console.WriteLine("The management team " + dep);
foreach (Employee employee in employees) {
