As a side note:
function ValidateInput : string;

The function raises an exception upon failure.
Since we did not have to follow Delphi here, a better declaration IMHO
would have been:
function ValidateInput (out ValidatedString: string): Boolean;

or as a pair of functions (like the conversion routines for strings):

function ValidateInput : string;
function TryValidateInput (out ValidatedString: string): Boolean;
