using regular expression in watin

I'm using regular expression in watin.

I have something like: ie.Button(Find.ByName(new Regex(input))).Click(); but I wan't to click on the second or third button that match and not the first one.

How can I do this?

From stackoverflow

• Try this:

  ie.Button(Find.ByName(new Regex(input)) && Find.ByIndex(1 /* or 2 */)).Click();
  

• Try this:

      ButtonCollection buttonCol = ie.Buttons;
      buttonCol = buttonCol.Filter(Find.ByName(new Regex(input)));
      buttonCol[1].Click();
      buttonCol[2].Click();
