Distance calculator in C#

I need a database and, preferably, the accompanying C# code, that will allow me to do a determination of distances between two grographic points on the globe.

A geographic point can be defined as:

- a US zip code

- a country

- (Optional) a city anywhere in the world

This would imply having a table listing the grographic location of all zip codes as well as a mathematical calculation to determine the distance, in miles, between two given zip codes. The code, although it would be preferred to be in C#, can be in pretty much any language.

Also, for locations outside of the United States, I need to know ballpack distances between them. It doesn't have to be exact - although accuracy down to the city would be ideal, distance from the center of the country could suffice. This, however, is not as much a priority as distance calculation in the US is.

If you can provide distances within the US but do not have the information for distances abroad, go ahead and post that anyway; I will take that in to consideration.

## Deliverables

b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.

3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).

Wanted to clarify something: we are not looking for an application. We are looking for the necessary data set and code snippet(s) needed to implement this functionality. No interface, no executable... just the data necessary to do the calculations and the means by which to do it.

This is to be integrated in to a larger, already existing application, and we will be doing said integration.

## Platform

Windows operating system. Database of information will ultimately be stored in MS SQL Server 2000, and data will be retrieved from a C/C++ or C# application.
