Editor.SelectAll with entity and layer selection filter                                                        By Virupaksha Aithal
While using “Editor.SelectAll” API, you can provide “SelectionFilter” to filter out the unwanted entities. Below code shows a simple example which only gets the Lines and circles from a specified layer only (0, Layer1, Layer2).

1. [CommandMethod("LayerSelection")]
   
2. public void LayerSelection()
   
3. {
   
4.     Document doc = Application.DocumentManager.MdiActiveDocument;
   
5.     Database db = doc.Database;
   
6.     Editor ed = doc.Editor;
   
7.     TypedValue[] filterlist = new TypedValue[2];
   
8.     //select circle and line
   
9.     filterlist[0] = new TypedValue(0, "CIRCLE,LINE");
   
10.     //8 = DxfCode.LayerName
    
11.     filterlist[1] = new TypedValue(8, "0,Layer1,Layer2");
    
12.     SelectionFilter filter =
    
13.                             new SelectionFilter(filterlist);
    
14.     PromptSelectionResult selRes = ed.SelectAll(filter);
    
15.     if (selRes.Status != PromptStatus.OK)
    
16.     {
    
17.         ed.WriteMessage(
    
18.                     "\nerror in getting the selectAll");
    
19.         return;
    
20.     }
    
21.     ObjectId[] ids = selRes.Value.GetObjectIds();
    
22.     ed.WriteMessage("No entity found: "
    
23.                            + ids.Length.ToString() + "\n");
    
24. }
