Check If Two SortedList Objects Are Equal in C#

To check if two SortedList objects are equal, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args) {
      SortedList list1 = new SortedList();
      list1.Add("One", 1);
      list1.Add("Two ", 2);
      list1.Add("Three ", 3);
      list1.Add("Four", 4);
      list1.Add("Five", 5);
      list1.Add("Six", 6);
      list1.Add("Seven ", 7);
      list1.Add("Eight ", 8);
      list1.Add("Nine", 9);
      list1.Add("Ten", 10);
      Console.WriteLine("SortedList1 elements...");
      foreach(DictionaryEntry d in list1) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      SortedList list2 = new SortedList();
      list2.Add("A", "Accessories");
      list2.Add("B", "Books");
      list2.Add("C", "Smart Wearable Tech");
      list2.Add("D", "Home Appliances");
      Console.WriteLine("
SortedList2 elements...");
      foreach(DictionaryEntry d in list2) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      SortedList list3 = new SortedList();
      list3 = list2;
      Console.WriteLine("
Is SortedList2 equal to SortedList3? = "+list3.Equals(list2));
   }
}

Output

This will produce the following output −

SortedList1 elements...
Eight  8
Five 5
Four 4
Nine 9
One 1
Seven  7
Six 6
Ten 10
Three  3
Two  2

SortedList2 elements...
A Accessories
B Books
C Smart Wearable Tech
D Home Appliances
Is SortedList2 equal to SortedList3? = True

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args) {
      SortedList list1 = new SortedList();
      list1.Add("One", 1);
      list1.Add("Two ", 2);
      list1.Add("Three ", 3);
      list1.Add("Four", 4);
      list1.Add("Five", 5);
      list1.Add("Six", 6);
      list1.Add("Seven ", 7);
      list1.Add("Eight ", 8);
      list1.Add("Nine", 9);
      list1.Add("Ten", 10);
      Console.WriteLine("SortedList1 elements (key-value pairs)...");
      foreach(DictionaryEntry d in list1) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      SortedList list2 = new SortedList();
      list2.Add("A", "Accessories");
      list2.Add("B", "Books");
      list2.Add("C", "Smart Wearable Tech");
      list2.Add("D", "Home Appliances");
      Console.WriteLine("
SortedList2 elements (key-value pairs)...");
      foreach(DictionaryEntry d in list2) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("
Is SortedList2 equal to SortedList1? = "+list2.Equals(list1));
   }
}

Output

This will produce the following output −

SortedList1 elements (key-value pairs)...
Eight  8
Five 5
Four 4
Nine 9
One 1
Seven  7
Six 6
Ten 10
Three  3
Two  2
SortedList2 elements (key-value pairs)...
A Accessories
B Books
C Smart Wearable Tech
D Home Appliances
Is SortedList2 equal to SortedList1? = False
