ZIP Code Utility

, 2 Jan 2005 CPOL 115K 3K 85
This article provides an easy method to lookup a U.S. City/State by ZIP Code, or one or more ZIP Codes by City/State. It also describes a method to calculate the distance between two ZIP Codes and find all other ZIP Codes within a radius of X miles of a specified ZIP Code.
using System;
using SagaraSoftware.ZipCodeUtil;

namespace ConsoleTest
{
	/// <summary>
	/// A test class to demonstrate the usage of the ZipCodeUtil library.
	/// </summary>
	class Driver
	{
		/// <summary>
		/// The main entry point for the application.
		/// </summary>
		[STAThread]
		static void Main (string[] args)
		{
			//	Location by ZIP Code.
			Location location = ZipCodeUtil.LookupByZipCode ("93275");
			if (null != location)
				Console.WriteLine (location.ToString ());

			//	Location(s) by City/State.
			Location[] locs = ZipCodeUtil.LookupByCityState ("Tulare", "CA");
			if (null != locs && locs.Length > 0)
			{
				foreach (Location loc in locs)
				{
					Console.WriteLine (loc.ToString ());
				}
			}

			//	Location by City/State/Zip
			location = ZipCodeUtil.LookupByCityStateZip ("Tulare", "CA", "93275");
			if (null != location)
				Console.WriteLine (location.ToString ());

			//	Distance between two locations.
			Location sf = ZipCodeUtil.LookupByZipCode ("94175");
			Location la = ZipCodeUtil.LookupByZipCode ("90185");
			Double dDistance = sf.DistanceFrom (la);
			Console.WriteLine ("{0} is {1} miles from {2}", sf.City, dDistance, la.City);

			//	Other Locations within an X-mile radius of a specific location.
			locs = sf.LocationsWithinRadius (5.0);
			if (null != locs && locs.Length > 0)
			{
				foreach (Location loc in locs)
				{
					Console.WriteLine (loc.ToString ());
				}
			}


			Console.ReadLine ();
