Obtaining the Layer States “Detailed Data” from an External DWG File

Leading on from this post Obtaining the Layer States from an External DWG file I had the question to list out the internal data from the LayerStatesManager dictionary Xrecords…        So here you go…         // list the layer states detailed data    // by Fenton Webb, DevTech, 07/08/2012    [CommandMethod("ListLayerStates")]    public void ListLayerStates()    {      Document doc = Application.DocumentManager.MdiActiveDocument;
