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:
Example 1:
// 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:
I first II second III third IV fourth V fifth
Example 2:
// 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( "A" , "Apple" ); // To show that the HybridDictionary is // case-sensitive myDict.Add( "a" , "Air" ); myDict.Add( "B" , "Banana" ); myDict.Add( "C" , "Cat" ); myDict.Add( "D" , "Dog" ); myDict.Add( "d" , "Dolphine" ); myDict.Add( "E" , "Elephant" ); myDict.Add( "F" , "Fish" ); // 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.
