C#语言本身不支持多继承,但可以通过接口、组合等方式来实现类似的功能。
interface IFlyable
{
void Fly();
}
interface ISwimmable
{
void Swim();
}
class Bird : IFlyable
{
public void Fly()
{
Console.WriteLine("Bird is flying");
}
}
class Fish : ISwimmable
{
public void Swim()
{
Console.WriteLine("Fish is swimming");
}
}
class Duck : IFlyable, ISwimmable
{
public void Fly()
{
Console.WriteLine("Duck is flying");
}
public void Swim()
{
Console.WriteLine("Duck is swimming");
}
}
class Engine
{
public void Start()
{
Console.WriteLine("Engine is starting");
}
}
class Car
{
private Engine engine = new Engine();
public void Start()
{
engine.Start();
Console.WriteLine("Car is starting");
}
}
通过以上两种方式,可以模拟实现类似多继承的效果。
