Can anyone please verify my code to load Ifc Structure

Dear Sir.
I have uploaded my code, please see if my code is fine. My code is giving me result but not in a good tree structure as OPEN IFC Viewer is giving

I found an example of loading spatial structure and i changed it according to my need. if you can correct the code please do help me

Please if anyone can see my code or if anyone can give his spatial structure reading code.

See https://docs.xbim.net/examples/spatial-hierarchy.html and https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD1/HTML/link/ifcspatialstructureelement.htm

I can't make a lot of sense of the above code. You've not provided LoadIfcStructure()

You generally need to use recursion to descent the nested hierarchy as per https://github.com/xBimTeam/XbimSamples/blob/2108efba47e628207c92e5ac23e1711b5de0ec99/BasicCreate/SpatialStructure.cs#L56
