How do i get type name in c# for zero touch node

Hello everyone

I’m currently trying to “play” a little around with zero touch nodes. At this point, I have recreated the stuff Github have made in their zero touch pack, and also some of the stuff Marcello Sgambelluri have made on the simply complex.

In the node i’m trying to create, one of the thinks i want to get is, the family type name(i think).
Example. if a have a wall, the wall have a certain name like, plaster wall 180 mm or something like that.
How do I access that parameter in C#, so I can use it as a output?

thank you in advance.
