如何使用C＃的策略模式？

问题描述

下面是我到目前为止有：

Here's what I have so far:

namespace Strategy
{
    interface IWeaponBehavior
    {
        void UseWeapon();
    }
}

namespace Strategy
{
    class Knife : IWeaponBehavior
    {
        public void UseWeapon()
        {
            Console.WriteLine("You used the knife to slash the enemy! SLASH SLASH!");
        }
    }
}

namespace Strategy
{
    class Pan : IWeaponBehavior
    {
        public void UseWeapon()
        {
            Console.WriteLine("You use the pan! 100% Adamantium power! BONG!");
        }
    }
}

现在超的.cs。怎么可能超实现weaponbehavior让孩子类可以更具体。

Now if I have a Character.cs superclass. how can that superclass implement a weaponbehavior so that children classes can be more specific.

namespace Strategy
{
    class Character
    {
        public IWeaponBehavior weapon;

        public Character(IWeaponBehavior specificWeapon)
        {
            weapon = specificWeapon;
        }        
    }
}

namespace Strategy
{
    class Thief : Character
    {

    }
}

我如何能实现这一点？我在什么实际的代码需要很困惑。

How can I implement this? I'm very confused on what the actual code needs to be.

我知道这可能会问太多，但如果你能编写实际的代码，所以我可以学习它，那将是非常好的你们的。我通过看代码学习。 ：P。很多人可能会受益于这个问题。

I know this might be asking too much, but if you could write the actual code so I could study it, that would be very nice of you guys. I learn by seeing code. :P Many people could benefit from this question.

推荐答案

使用依赖注入类字符？

public class Character
{
    public Character(IWeaponBehavior weapon) 
    {
        this.weapon = weapon;
    }

    public void Attack()
    {
        weapon.UseWeapon();
    }

    IWeaponBehavior weapon;
}

public class Princess: Character
{
    public Princess() : base(new Pan()) { }
}

public class Thief: Character
{
    public Thief() : base(new Knife()) { }
}

...

Princess p = new Princess();
Thief t = new Thief();

p.Attack(); // pan
t.Attack(); // knife
