本文探讨了工厂模式在创建不同类型的用户实例中的应用，包括管理员、普通用户和监督员，通过工厂方法简化了创建过程，并展示了如何利用泛型进行更灵活的实例创建。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace BeautyCode.DesignPattern.Head.First.Factory
{
public enum UserType
{
Admin,
Supervisor,
Common
}
public abstract class User
{
public virtual UserType UserType
{
get;
protected set;
}
public User(UserType userType)
{
UserType = userType;
}
public virtual string Username
{
get;
set;
}
public virtual int Age
{
get;
set;
}
public virtual void DisplayName()
{
Console.WriteLine("my name is {0}, i'm {1} years old.", Username, Age);
}
}
public class AdminUser : User
{
public AdminUser()
: base(UserType.Admin)
{ }
}
public class CommonUser : User
{
public CommonUser()
: base(UserType.Common)
{ }
}
public class SupervisorUser : User
{
public SupervisorUser()
: base(UserType.Supervisor)
{
}
}
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace BeautyCode.DesignPattern.Head.First.Factory
{
public class UserFactory
{
public static User CreateSingleUser(UserType userType)
{
User user = null;
switch (userType)
{
case UserType.Admin :
user = new AdminUser(); 
break;
case UserType.Common :
user = new CommonUser();
break;
case UserType.Supervisor :
user = new SupervisorUser();
break;
default :
break;
}
return user;
}
}
}

调用代码

Head.First.Factory.User user = Head.First.Factory.UserFactory.CreateSingleUser(Head.First.Factory.UserType.Admin);
