Get an enumerator that iterates through the SortedDictionary in C#

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

Example

 Live Demo

using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedDictionary<int, string>sortedDict = new SortedDictionary<int, string>();
      sortedDict.Add(100, "Mobile");
      sortedDict.Add(200, "Laptop");
      sortedDict.Add(300, "Desktop");
      sortedDict.Add(400, "Speakers");
      sortedDict.Add(500, "Headphone");
      sortedDict.Add(600, "Earphone");
      Console.WriteLine("SortedDictionary key-value pairs...");
      IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator();
      while (demoEnum.MoveNext())
         Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
   }
}

Output

This will produce the following output −

SortedDictionary key-value pairs...
Key = 100, Value = Mobile
Key = 200, Value = Laptop
Key = 300, Value = Desktop
Key = 400, Value = Speakers
Key = 500, Value = Headphone
Key = 600, Value = Earphone

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedDictionary<int, int> sortedDict = new SortedDictionary<int, int>();
      sortedDict.Add(100, 1);
      sortedDict.Add(200, 2);
      sortedDict.Add(300, 3);
      sortedDict.Add(400, 4);
      sortedDict.Add(500, 5);
      sortedDict.Add(600, 6);
      sortedDict.Add(700, 7);
      sortedDict.Add(800, 8);
      sortedDict.Add(900, 9);
      sortedDict.Add(1000, 10);
      Console.WriteLine("SortedDictionary key-value pairs...");
      IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator();
      while (demoEnum.MoveNext())
         Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
   }  
}

Output

This will produce the following output −

SortedDictionary key-value pairs...
Key = 100, Value = 1
Key = 200, Value = 2
Key = 300, Value = 3
Key = 400, Value = 4
Key = 500, Value = 5
Key = 600, Value = 6
Key = 700, Value = 7
Key = 800, Value = 8
Key = 900, Value = 9
Key = 1000, Value = 10
