Check if two StringDictionary objects are equal or not in C#

To check if two StringDictionary objects are equal or not, the code is as follows −

Example

 Live Demo

using System; 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");       StringDictionary strDict2 = new StringDictionary();       strDict2.Add("A", "John");       strDict2.Add("B", "Andy");       strDict2.Add("C", "Tim");       strDict2.Add("D", "Ryan");       strDict2.Add("E", "Kevin");       strDict2.Add("F", "Katie");       strDict2.Add("G", "Brad");       StringDictionary strDict3 = new StringDictionary();       strDict3 = strDict2;       Console.WriteLine("Is Dictionary2 equal to Dictionary3? = "+strDict2.Equals(strDict3));       Console.WriteLine("Is Dictionary1 equal to Dictionary3? = "+strDict1.Equals(strDict3));    } }

Output

This will produce the following output −

Is Dictionary2 equal to Dictionary3? = True Is Dictionary1 equal to Dictionary3? = False

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 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 d in strDict1) {          Console.WriteLine(d.Key + " " + d.Value);       }       StringDictionary strDict2 = new StringDictionary();       strDict2.Add("A", "John");       strDict2.Add("B", "Andy");       strDict2.Add("C", "Tim");       strDict2.Add("D", "Ryan");       strDict2.Add("E", "Kevin");       strDict2.Add("F", "Katie");       strDict2.Add("G", "Brad");       Console.WriteLine("
StringDictionary2 elements...");       foreach(DictionaryEntry d in strDict2) {          Console.WriteLine(d.Key + " " + d.Value);       }       Console.WriteLine("
Is Dictionary2 equal to Dictionary1? = "+strDict2.Equals(strDict1));    } }

Output

This will produce the following output −

StringDictionary1 elements... a John b Andy c Tim d Ryan e Kevin f Katie g Brad StringDictionary2 elements... a John b Andy c Tim d Ryan e Kevin f Katie g Brad Is Dictionary2 equal to Dictionary1? = False
