在中实现多个接口和对象实例。净

它们是指同一个对象,还是有三个不同的对象?

interface IMyInterface
{
    void MyFunction();
}

interface IYourInterface()
{
    void YourFunction();
}

interface IOurInterface()
{
    void OurFunction();
}

public class MainImplementation : IMyInterface, IYourInterface, IOurInterface
{
    public void MyFunction() { }
    public void YourFunction() { }
    public void OurFunction() { }
}

private IMyInterface myInterface;
private IYourInterface yourInterface;
private IOurInterface ourInterface;

static void Main(string[] args)
{
    myInterface = new MainImplementation() as IMyInterface;
    yourInterface = myInterface as IYourInterface;
    ourInterface = myInterface as IOurInterface;
}
