"It does not work" does not provide much information about what exactly your issue is. Any error message, how do you call AcadDocument.SendCommand() (the code executed before and after the call, which does matter if you HAVE TO use SendCommand())?

But, since you use COM Interop, why do you have to use SendCommand() to attach XRef instead of using AcadModelSpace/PaperSpace.AttachExternalReference()?

An Xref is an AcadBlock.

So, you loop through ThisDrawing.Blocks collection, search for AcadBlock with IsXref = True. Once you find the targetting AcadBlock (Xref), you can call

AcadBlock.Bind/Detach/Reload/Unload()...
