IsNumeric Best Practices

Needing to find out what the best why to implement the IsNumeric function in C# is, I went on a brief tour of the Internet today.  My result is a very informative article by J. Ambrose Little that benchmarks six (count 'em, six) different techniques.  The result is a virtual tie between an incremental character technique (use the Char.IsNumeric method on each character in a string), the Double.TryParse and VisualBasic.IsNumeric.  Useful information to keep in mind in the future.
