can someone translate this to vb please?



private static void FindObjectsInXREF(GraphNode root, string layerName, string xrefName, out List<ObjectId> polyObjIds)
polyObjIds = new List<ObjectId>();
for (int o = 0; o < root.NumOut; o++)
XrefGraphNode child = root.Out(o) as XrefGraphNode;
if (child.XrefStatus == XrefStatus.Resolved && child.Name == xrefName)
BlockTableRecord bl = child.BlockTableRecordId.GetObject(OpenMode.ForRead) as BlockTableRecord;
foreach (ObjectId objId in bl)
Autodesk.AutoCAD.DatabaseServices.Entity ent = objId.GetObject(OpenMode.ForRead) as Autodesk.AutoCAD.DatabaseServices.Entity;
Type entType = ent.GetType();
if (ent.Layer == xrefName + "|" + layerName && (entType == typeof(Polyline) ||
entType == typeof(Polyline) ||
entType == typeof(Alignment) ||
entType == typeof(Polyline3d) ||
entType == typeof(Polyline2d)))




i also need to a filterselection on the xref for a certain layer otherwise the program might get slow with large dawings


thx in advance
