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。
