Count the number of key/value pairs in HybridDictionary in C#

CsharpServer Side ProgrammingProgramming

To count the number of key/value pairs in HybridDictionary, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      HybridDictionary dict1 = new HybridDictionary();
      dict1.Add("A", "SUV");
      dict1.Add("B", "MUV");
      dict1.Add("C", "AUV");
      Console.WriteLine("HybridDictionary1 elements...");
      foreach(DictionaryEntry d in dict1){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Count of Key/value pairs in Dictionary1 = "+dict1.Count);
      HybridDictionary dict2 = new HybridDictionary();
      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("\nHybridDictionary2 elements...");
      foreach(DictionaryEntry d in dict2){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Count of Key/value pairs in Dictionary2 = "+dict1.Count);
      dict2.Clear();
      Console.WriteLine("Count of Key/value pairs in Dictionary2 (Updated) = "+dict2.Count);
   }
}

Output

This will produce the following output −

HybridDictionary1 elements...
A SUV
B MUV
C AUV
Count of Key/value pairs in Dictionary1 = 3

HybridDictionary2 elements...
1 One
2 Two
3 Three
4 Four
5 Five
6 Six
Count of Key/value pairs in Dictionary2 = 3
Count of Key/value pairs in Dictionary2 (Updated) = 0

Example

Let us now see another example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      HybridDictionary dict = new HybridDictionary();
      dict.Add("A", "SUV");
      dict.Add("B", "MUV");
      dict.Add("C", "AUV");
      Console.WriteLine("HybridDictionary elements...");
      foreach(DictionaryEntry d in dict){
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("Count of Key/value pairs in Dictionary = "+dict.Count);
      dict.Add("D", "Utility Vehicle");
      dict.Add("E", "Convertible");
      Console.WriteLine("Count of Key/value pairs in Dictionary (Updated) = "+dict.Count);
   }
}

Output

This will produce the following output −

HybridDictionary elements...
A SUV
B MUV
C AUV
Count of Key/value pairs in Dictionary = 3
Count of Key/value pairs in Dictionary (Updated) = 5
