在C#中,由于語言本身不支持多繼承,可以通過使用接口、組合和委托等技術(shù)來實現(xiàn)多繼承的策略。
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();
}
}
通過以上方法,可以在C#中實現(xiàn)多繼承的策略,靈活地組合不同類的功能來實現(xiàn)復(fù)雜的對象行為。
