C# | Creating an empty casesensitive HybridDictionary Class (original) (raw)
Last Updated : 16 Nov, 2022
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:
CSHARP `
// 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:
CSHARP `
// 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 Dolphin 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.
