How to get the property value of a class based on property number

I tried to search for an already posted answer, but was unable to find any, although some threads provided some hints.

What I normally do to set the same property across numbered instances of controls is something like:

  DirectCast(Me.Controls.Item("Picturebox" & port), PictureBox).Tag = "some tag"

Is there a similar approach if I want to loop around numbered properties class1.property1 to class1.property99 of a class?
