如何创建有意义的动态属性?

        IODevice dio = new IODevice();

        try
        {
            dio.Pin["IsBirdInCageSensor"].Set();
            dio.Pin["KillBird"].Get();
            //dio.Pin["NonExistant"].Set(); //exception
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }

这里的管脚是数字IO盒中的一系列IO线,可以高(1)或低(0)。

我想使用dynamic以以下方式调用它:

        dio.Pins.KillBird.Get();

class IODevice
{
    public IODevice()
    {
        pin = new PinCollection();
        pin.Add(new Pin("IsBirdInCageSensor", 0));
        pin.Add(new Pin("KillBird", 1));
    }

    private PinCollection pin;
    public PinCollection Pin { get { return pin; } }

    public dynamic Pins { get; private set; }
}
