using System.Collections;
public class Demo {
   public static void Main(){
      Hashtable hash = new Hashtable(10);
      hash.Add("1", "SUV");
      hash.Add("2", "Electric Cars");

      hash.Add("6", "Sedan");
      hash.Add("7","Crossover");
      Console.WriteLine("Enumerator to iterate through the Hashtable...");
      IDictionaryEnumerator demoEnum = hash.GetEnumerator();
      while (demoEnum.MoveNext())
         Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
   }
}

यह निम्नलिखित आउटपुट उत्पन्न करेगा -

Enumerator to iterate through the Hashtable...
Key = 1, Value = SUV
Key = 2, Value = Electric Cars
Key = 3, Value = AUV
Key = 4, Value = Utility Vehicle
Key = 5, Value = Compact Car
Key = 6, Value = Sedan
Key = 7, Value = Crossover
