How to filter entities in xref file

[Anonymous]

Hi,

I used c# to attached a xref 1.dwg to host.dwg, yet still scratching the head on how to read entities on layer 'abc'  in 1.dwg from host.dwg.

Any suggestions, please? 

Thank you in advance.

You have to find Database corresponding to "1.dwg" and iterate it ModelSpace (or PaperSpace, or both ModelSpace and PaperSpace) checking layers of all entities.

Sample to getting all xrefs: http://adndevblog.typepad.com/autocad/2012/06/finding-all-xrefs-in-the-current-database-using-cnet.h...

XrefGraphNode.Database allow to get Database of appropriate Xref.
