.NET Postal Address Parser

I need a postal address parser for an upcoming project. The user will enter free-form addresses like : Bob's Warehouse ATTN: Jim 1234 Main Street Suite 46 (obviously, optional) Anytown, AnyState 90210 USA As well as non-US addresses (as much as possible). I realize that parsing physical addresses is tedious and often impossible, but I don't need something "perfect". I need reliable code to get address1, address2, city, state/province, zip/postal code, and country and "other" (which would be the 'Bob's Warehouse and ATTN: Jim' parts of the above example) from that blob of text. And reliable and graceful error handling when a problem is run into. This will be user entered free-form text, so lord knows what will come through!
