Check the HybridDictionary for a specific key in C#

CsharpServer Side ProgrammingProgramming

To check the HybridDictionary for a specified key, 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 dict = new HybridDictionary(5);
      dict.Add("A", "AB");
      dict.Add("B", "BC");
      dict.Add("C", "DE");
      dict.Add("D", "FG");
      dict.Add("E", "HI");
      Console.WriteLine("Key/Value pairs...");
      foreach(DictionaryEntry d in dict)
      Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
      Console.WriteLine("Does HybridDictionary contains the key C? = "+dict.Contains("C"));
   }
}

Output

This will produce the following output −

Key/Value pairs...
Key = A, Value = AB
Key = B, Value = BC
Key = C, Value = DE
Key = D, Value = FG
Key = E, Value = HI
Does HybridDictionary contains the key C? = True

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 dict1 = new HybridDictionary();
      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("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);
      Console.WriteLine("Does HybridDictionary2 contains the key 10? = "+dict2.Contains(10));
      dict2.Clear();
      Console.WriteLine("Count of Key/value pairs in Dictionary2 (Updated) = "+dict2.Count);
   }
}

Output

This will produce the following output −

HybridDictionary1 elements...
A Books
B Electronics
C Smart Wearables
D Pet Supplies
E Clothing
F Footwear
Count of Key/value pairs in Dictionary1 = 6

HybridDictionary2 elements...
1 One
2 Two
3 Three
4 Four
5 Five
6 Six
Count of Key/value pairs in Dictionary2 = 6
Does HybridDictionary2 contains the key 10? = False
Count of Key/value pairs in Dictionary2 (Updated) = 0
