static public void test() // This method can have any name
  {
   Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;  ;
   TypedValue[] filList = new TypedValue[]
   { new TypedValue(0,"PolyLine"),new TypedValue((int)DxfCode.LayerName, "地质点") };
         SelectionFilter filter = new SelectionFilter(filList); 
   PromptSelectionResult res = ed.GetSelection( filter);
   if (res.Status != PromptStatus.OK)
    return;
   Autodesk.AutoCAD.EditorInput.SelectionSet SS = res.Value;
   ObjectId[] idArray;
   idArray = SS.GetObjectIds();
   foreach (ObjectId employeeId in idArray)
   {ed.WriteMessage(employeeId.ToString());
