Check if two ListDictionary objects are equal in C#

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

Example

 Live Demo

using System; using System.Collections; using System.Collections.Specialized; public class Demo {    public static void Main(){       ListDictionary dict1 = new ListDictionary();       dict1.Add("A", "Books");       dict1.Add("B", "Electronics");       dict1.Add("C", "Smart Wearables");       dict1.Add("D", "Pet Supplies");       dict1.Add("E", "Clothing");       dict1.Add("F", "Footwear");       Console.WriteLine("ListDictionary1 elements...");       foreach(DictionaryEntry d in dict1){          Console.WriteLine(d.Key + " " + d.Value);       }       ListDictionary dict2 = new ListDictionary();       dict2.Add("1", "One");       dict2.Add("2", "Two");       dict2.Add("3", "Three");       dict2.Add("4", "Four");       dict2.Add("5", "Five");       dict2.Add("6", "Six");       Console.WriteLine("
ListDictionary2 elements...");       foreach(DictionaryEntry d in dict2){          Console.WriteLine(d.Key + " " + d.Value);       }       ListDictionary dict3 = new ListDictionary();       dict3 = dict2;       Console.WriteLine("
Is ListDictionary3 equal to ListDictionary2? = "+(dict3.Equals(dict2)));    } }

Output

This will produce the following output −

ListDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear ListDictionary2 elements... 1 One 2 Two 3 Three 4 Four 5 Five 6 Six Is ListDictionary3 equal to ListDictionary2? = True

Example

Let us see another example −

 Live Demo

using System; using System.Collections; using System.Collections.Specialized; public class Demo {    public static void Main(){       ListDictionary dict1 = new ListDictionary();       dict1.Add("A", "Books");       dict1.Add("B", "Electronics");       dict1.Add("C", "Smart Wearables");       dict1.Add("D", "Pet Supplies");       dict1.Add("E", "Clothing");       dict1.Add("F", "Footwear");       Console.WriteLine("ListDictionary1 elements...");       foreach(DictionaryEntry d in dict1){          Console.WriteLine(d.Key + " " + d.Value);       }       ListDictionary dict2 = new ListDictionary();       dict2.Add("1", "One");       dict2.Add("2", "Two");       dict2.Add("3", "Three");       dict2.Add("4", "Four");       dict2.Add("5", "Five");       dict2.Add("6", "Six");       Console.WriteLine("
ListDictionary2 elements...");       foreach(DictionaryEntry d in dict2){          Console.WriteLine(d.Key + " " + d.Value);       }       Console.WriteLine("
Is ListDictionary1 equal to ListDictionary2? = "+(dict1.Equals(dict2)));    } }

Output

This will produce the following output −

ListDictionary1 elements... A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear ListDictionary2 elements... 1 One 2 Two 3 Three 4 Four 5 Five 6 Six Is ListDictionary1 equal to ListDictionary2? = False
