thanks advice

combine 2 array list one:

list<string> lista = new arraylist<string>(); lista.add("a");  list<string> listb = new arraylist<string>(); listb.add("b");  list<string> listfinal = new arraylist<string>(); listfinal.addall(lista); listfinal.addall(listb); 

or can append listb :

listb.addall(lista);
