you can use simple recursive function:

list<string> checkednames( system.windows.forms.treenodecollection thenodes) {     list<string> aresult = new list<string>();      if ( thenodes != null )     {         foreach ( system.windows.forms.treenode anode in thenodes )         {             if ( anode.checked )             {                 aresult.add( anode.text );             }              aresult.addrange( checkednames( anode.nodes ) );         }     }      return aresult; }

just use on yourtreeview.nodes
