That's fairly simple:

StringComparer comparer = StringComparer.Ordinal;
if (comparer.Compare(myString, "a") >= 0 &&
    comparer.Compare(myString, "au") < 0)
{
    // Do stuff
}

That will include "atzzzz" but not "au" itself. Adjust bounds as required - and likewise choose a different StringComparer if necessary (e.g. a case-insensitive or culture-sensitive one).
