By the way to save yourself going completely mad when writing regexes, C#
designers had the foresight to include an uninterpolated string literal syntax:

  NumberReg = new Regex( @"^[+-]?\d*\.?\d*(e?[+-]?\d*" );

This means that all escapes get passed directly to the regex parser. Also
useful when writing DOS-style paths.
