多个类实现相同接口的问题

public interface IShape
{
    void Draw();
}

public class Circle : IShape
{
    public void Draw()
    {
        Console.WriteLine("Drawing a circle");
    }
}

public class Square : IShape
{
    public void Draw()
    {
        Console.WriteLine("Drawing a square");
    }
}

public interface ICalculator
{
    int Add(int a, int b);
}

public class BasicCalculator : ICalculator
{
    public int Add(int a, int b)
    {
        return a + b;
    }
}

public class ScientificCalculator : ICalculator
{
    public int Add(int a, int b)
    {
        // 假设这里有一些复杂的计算逻辑
        return a + b;
    }
}

public interface IOldShape
{
    void Draw();
}

public interface INewShape
{
    void Render();
}

public class ShapeAdapter : INewShape
{
    private IOldShape _oldShape;

    public ShapeAdapter(IOldShape oldShape)
    {
        _oldShape = oldShape;
    }

    public void Render()
    {
        _oldShape.Draw();
    }
}
