C# | Creating an empty case-sensitive HybridDictionary Class

HybridDictionary() creates an empty case-sensitive HybridDictionary.

Syntax:

public HybridDictionary ();

Below given are some examples to understand the implementation in a better way:

// C# code to create an empty
// case-sensitive HybridDictionary.
using System;
using System.Collections;
using System.Collections.Specialized;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating an empty case-sensitive
        // HybridDictionary named myDict
        HybridDictionary myDict = new HybridDictionary();
  
        // Adding key/value pairs in myDict
        myDict.Add("I", "first");
        myDict.Add("II", "second");
        myDict.Add("III", "third");
        myDict.Add("IV", "fourth");
        myDict.Add("V", "fifth");
  
        // Displaying the key/value pairs in myDict
        foreach(DictionaryEntry de in myDict)
            Console.WriteLine(de.Key + " " + de.Value);
    }
}

}

Output:

A Apple
a Air
B Banana
C Cat
D Dog
d Dolphine
E Elephant
F Fish

Note:

  • By default, the collection is case-sensitive.
  • The comparer determines whether two keys are equal. Every key in a HybridDictionary must be unique.
  • This constructor is an O(1) operation.
