I have an arraylist that contains string [] objects.  The arraylist looks like

arraylist.add(new string [] {name, phone});

How can I sort the arraylist by name?

Create a class that implements IComparer and use that to sort the ArrayList:
public class PhoneComparer : IComparer  {
   int IComparer.Compare(object x, object y) {
      return string.Compare(((string[])x)[0], ((string[])y)[0]);
arraylist.Sort(new PhoneComparer());
