# ZIP Code Utility

, 2 Jan 2005
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.
 App.ico bin Release ConsoleTest.exe SagaraSoftware.ZipCodeUtil.dll DataProvider ```using System; using SagaraSoftware.ZipCodeUtil; namespace ConsoleTest { /// /// A test class to demonstrate the usage of the ZipCodeUtil library. /// class Driver { /// /// The main entry point for the application. /// [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 (); } } } ```
