C#组合模式实例详解

本文实例讲述了c#组合模式。分享给大家供大家参考。具体如下：

company.cs如下：

using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
  public abstract class company
  {
    protected string name;
    public company(string name) 
    {
      this.name = name;
    }
    public abstract void add(company c);
    public abstract void remove(company c);
    public abstract void display(int depth);
    public abstract void lineofduty();
  }
}

concretecompany.cs如下：

using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
  public class concretecompany:company
  {
    private list<company> children = new list<company>();
    public concretecompany(string name) 
      :base(name)
    {}
    public override void add(company c)
    {
      children.add(c);
    }
    public override void remove(company c)
    {
      children.remove(c);
    }
    public override void display(int depth)
    {
      console.writeline(new string('-',depth)+name);
      foreach(company component in children)
      {
        component.display(depth+2);
      }
    }
    public override void lineofduty()
    {
      foreach(company component in children)
      {
        component.lineofduty();
      }
    }
  }
}

financedepartment.cs如下：

using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
  public class financedepartment:company
  {
    public financedepartment(string name) : base(name) { }
    public override void add(company c)
    {
    }
    public override void remove(company c)
    {
      
    }
    public override void display(int depth)
    {
      console.writeline(new string('-',depth)+name);
    }
    public override void lineofduty()
    {
      console.writeline("{0} 财务支付管理",name);
    }
  }
}

hrdepartment.cs如下：

using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
  public class hrdepartment:company
  {
    public hrdepartment(string name)
      :base(name)
    { }
    public override void add(company c)
    {
    }
    public override void remove(company c)
    {
    }
    public override void display(int depth)
    {
      console.writeline(new string('-',depth)+name);
    }
    public override void lineofduty()
    {
      console.writeline("{0} 招聘培训管理",name);
    }
  }
}

program.cs如下：

using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
  class program
  {
    static void main(string[] args)
    {
      concretecompany root = new concretecompany("北京总共司");
      root.add(new hrdepartment("人力部"));
      root.add(new financedepartment("财务部"));
      concretecompany comp = new concretecompany("上海分公司");
      comp.add(new hrdepartment("分工司人力部"));
      comp.add(new financedepartment("分公司财务部"));
      root.add(comp);
      concretecompany comp1 = new concretecompany("南京分部");
      comp1.add(new hrdepartment("南京人力部"));
      comp1.add(new financedepartment("南京财务部"));
      comp.add(comp1);
      concretecompany comp2 = new concretecompany("杭洲分部");
      comp2.add(new hrdepartment("杭州人事部"));
      comp2.add(new financedepartment("杭州财务部"));
      comp.add(comp2);
      root.display(1);
      console.readkey();
    }
  }
}

希望本文所述对大家的c#程序设计有所帮助。
