C#组合模式实例详解

前端技术 2023/09/05 C#

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。
