How to stop a random string generator from repeating a string consecutively?

Question

Is there a way for this random string generator to stop repeating a string consecutively?

 public class ButtonText : MonoBehaviour
 {
 public Text TextField;

 public void PickRandomFromList()
 {
     string[] letters = new string[] {"A", "B", "C", "D", "E", "F"};
     string randomName = letters[Random.Range(0, letters.Length)];
     TextField.text = randomName;
 }

If you wish to avoid the function picking the same letter twice in a row, just store the previous value:

  private string lastLetter="";
  public void PickRandomFromList()
  {
      string[] letters = new string[] {"A", "B", "C", "D", "E", "F"};
      string randomName;
      do {
          randomName = letters[Random.Range(0, letters.Length)];
      } while (randomName == lastLetter);
      lastLetter = randomName;
      TextField.text = randomName;
  }
