SelectByID2 Name

I have an add-in I'm working on trying to get the names within an assembly to edit a dimension.  When I record a macro, I can get the dimensions name, but I want my add-in to allow the user to select the dimension and then display it to the user.  Here's a portion of the recorded macro:

swDoc.ActivateSelectedFeature();

boolstatus = swDoc.Extension.SelectByID2("D1@STOCK@Base Cylinder-1@L_S/Rear Cover-1@Base Cylinder", "DIMENSION", -0.13610586623579712, 0.064932066534194435, 0.047917612974635 false, 0, null, 0);

            swDoc.ClearSelection2(true);

What I can't seem to figure out is how to get the selected object to return that entire name.

I've tried GetNameForSelection, FullName and just name and all I can get is "D1@STOCK"

Anyone know how to do this?

Thanks
