Get an enumerator that iterates through the StringDictionary in C#

CsharpServer Side ProgrammingProgramming

To get an enumerator that iterates through StringDictionary, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      StringDictionary strDict1 = new StringDictionary();
      strDict1.Add("A", "John");
      strDict1.Add("B", "Andy");
      strDict1.Add("C", "Tim");
      strDict1.Add("D", "Ryan");
      strDict1.Add("E", "Kevin");
      strDict1.Add("F", "Katie");
      strDict1.Add("G", "Brad");
      Console.WriteLine("StringDictionary1 elements...");
      foreach(DictionaryEntry de in strDict1) {
         Console.WriteLine(de.Key + " " + de.Value);
      }
      StringDictionary strDict2 = new StringDictionary();
      strDict2.Add("1", "A");
      strDict2.Add("2", "B");
      strDict2.Add("3", "C");
      strDict2.Add("4", "D");
      strDict2.Add("5", "E");
      Console.WriteLine("\nStringDictionary2 key-value pairs...");
      IEnumerator demoEnum = strDict2.GetEnumerator();
      DictionaryEntry d;
      while (demoEnum.MoveNext()) {
         d = (DictionaryEntry)demoEnum.Current;
         Console.WriteLine("Key = " + d.Key + ", Value = " + d.Value);
      }
   }
}

Output

This will produce the following output −

StringDictionary1 elements...
a John
b Andy
c Tim
d Ryan
e Kevin
f Katie
g Brad

StringDictionary2 key-value pairs...
Key = 1, Value = A
Key = 2, Value = B
Key = 3, Value = C
Key = 4, Value = D
Key = 5, Value = E

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      StringDictionary strDict = new StringDictionary();
      strDict.Add("1", "One");
      strDict.Add("2", "Two");
      strDict.Add("3", "Three");
      strDict.Add("4", "Four");
      Console.WriteLine("StringDictionary key-value pairs...");
      IEnumerator demoEnum = strDict.GetEnumerator();
      DictionaryEntry d;
      while (demoEnum.MoveNext()) {
         d = (DictionaryEntry)demoEnum.Current;
         Console.WriteLine("Key = " + d.Key + ", Value = " + d.Value);
      }
   }
}

Output

This will produce the following output −

StringDictionary key-value pairs...
Key = 1, Value = One
Key = 2, Value = Two
Key = 3, Value = Three
Key = 4, Value = Four
