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();
    }
  }
}
