सी # में हैशटेबल के माध्यम से पुनरावृत्त करने वाला एक गणक प्राप्त करें

एक एन्यूमरेटर प्राप्त करने के लिए जो हैशटेबल के माध्यम से पुनरावृत्त करता है, कोड इस प्रकार है -

उदाहरण

using System;
using System.Collections;
public class Demo {
   public static void Main(){
      Hashtable hash = new Hashtable(10);
      hash.Add("1", "A");
      hash.Add("2", "B");
      hash.Add("3", "C");

      Console.WriteLine("Hashtable Key and Value pairs...");
      foreach(DictionaryEntry entry in hash){
         Console.WriteLine("{0} and {1} ", entry.Key, entry.Value);
      }
      Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize);

   }
}

आउटपुट

यह निम्नलिखित आउटपुट देगा -

Hashtable Key and Value pairs...
10 and J
1 and A
2 and B
3 and C
4 and D
5 and E
6 and F
7 and G
8 and H
9 and I
Is the Hashtable having fixed size? = False
Count of entries in Hashtable = 10 

Enumerator to iterate through the Hashtable...
Key = 10, Value = J
Key = 1, Value = A
Key = 2, Value = B
Key = 3, Value = C
Key = 4, Value = D
Key = 5, Value = E
Key = 6, Value = F
Key = 7, Value = G
Key = 8, Value = H
Key = 9, Value = I
