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
