Using the Cast:


ArrayList arrayList = new ArrayList();
arrayList.Add("Adams");
arrayList.Add("Arthur");
arrayList.Add("Buchanan");

IEnumerable<string> names = arrayList.Cast<string>().Where(n => n.Length < 7);
foreach(string name in names)
  Console.WriteLine(name);

 ArrayList arrayList = new ArrayList();
arrayList.Add("Adams");
arrayList.Add("Arthur");
arrayList.Add("Buchanan");

IEnumerable<string> names = arrayList.OfType<string>().Where(n => n.Length < 7);
foreach(string name in names)
  Console.WriteLine(name);

OUTPUT:

Adams
Arthur
