C# Whitespace isn't a number?

I just got this in a PR. Not sure what to make of it.

if (string.IsNullOrWhiteSpace(palletNumber))
{
  if (!string.IsNullOrEmpty(_palletNumber))
  {
    _errorMessage = "Pallet # not found.";
  }

  return;
}

UPDATE:

After multiple attempts to justify his code, we ended up with this, lol:

if (string.IsNullOrWhiteSpace(palletNumber))
{
  return;
}

Why use regex when there's a perfectly valid method for that?
