simple data masking in C#

Question

Is there a simple algorithm where by I can convert an numeric value to alphanumeric and reliably convert back it to the same numeric ?

ex: 12345 -> 00A3DF -> 12345

Thanks

I assume when you say alphanumeric you mean hexadecimal. This has already been answered:
