      // Declare a Hashtable object:
      Hashtable ziphash = new Hashtable();

      // Add entries using the Add() method:
      ziphash.Add("98008", "Bellevue");
      ziphash.Add("98052", "Redmond");
      ziphash.Add("98201", "Everett");
      ziphash.Add("98101", "Seattle");
      ziphash.Add("98371", "Puyallup");

      // Display contents:
      Console.WriteLine("Zip code       City");
      foreach (string zip in ziphash.Keys) 
      {
