when i open a dwg file, and the i can use mouse to click one graphical object, like a line, a circle, an arc and so forth. so my question is, what event is raised when i just click an object, and how can i moniter it? Can anyone post some code for me? That would be of great helpful, thanks!

The below code I copied from here

Preventing AutoCAD objects from being selected

 void OnSelectionAdded(object sender, SelectionAddedEventArgs e)
        {
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Editor ed = doc.Editor;

            ObjectId[] addedIds = e.AddedObjects.GetObjectIds();

            for (int i = 0; i < addedIds.Length; i++)
            {

                ObjectId oid = addedIds[i];

                ed.WriteMessage("Selected Item : " +(oid.ObjectClass.DxfName));


            }

        }
