List custom class members and type

List custom class members and type

This seems like the most basic thing ever but somehow I couldnt find the
answer and couldnt figure it out.
Lets say I have a custom class:
public class WineCellar
{
public string year;
public string wine;
public double nrbottles;
}
Now I would like a function:
WineCellar ex = new WineCellar();
ex.members();
This should return: year, wine, nrbootles.
And:
ex.members().types();
Should return: string, string, double
I guess on the same note, lets say you have one instance {2010, Rioja, 6}.
Is there syntax that returns these by indexing? i.e.
ex[1]
or
ex.{1}
that returns 2010?
Sorry for the basic question.
