在C#中,由于语言本身不支持多继承,可以通过使用接口、组合和委托等技术来实现多继承的策略。
interface IFlyable
{
void Fly();
}
interface ISwimmable
{
void Swim();
}
class Bird : IFlyable
{
public void Fly()
{
Console.WriteLine("I am flying");
}
}
class Fish : ISwimmable
{
public void Swim()
{
Console.WriteLine("I am swimming");
}
}
class FlyingFish : IFlyable, ISwimmable
{
private Bird bird = new Bird();
private Fish fish = new Fish();
public void Fly()
{
bird.Fly();
}
public void Swim()
{
fish.Swim();
}
}
class FlyingFish
{
private Bird bird = new Bird();
private Fish fish = new Fish();
public void Fly()
{
bird.Fly();
}
public void Swim()
{
fish.Swim();
}
}
class FlyingFish
{
private Action flyAction;
private Action swimAction;
public FlyingFish()
{
Bird bird = new Bird();
Fish fish = new Fish();
flyAction = bird.Fly;
swimAction = fish.Swim;
}
public void Fly()
{
flyAction();
}
public void Swim()
{
swimAction();
}
}
通过以上方法,可以在C#中实现多继承的策略,灵活地组合不同类的功能来实现复杂的对象行为。
