C# | Creating a Case-Sensitive HybridDictionary with specified initial size
Last Updated :
16 Nov, 2022
HybridDictionary(Int32) constructor is used to create a case-sensitive HybridDictionary with the specified initial size. Syntax:
public HybridDictionary (int initialSize);
Here, initialSize is the approximate number of entries that the HybridDictionary can initially contain. Below given are some examples to understand the implementation in a better way: Example 1:
CSHARP
using System;
using System.Collections;
using System.Collections.Specialized;
class GFG {
public static void Main()
{
HybridDictionary myDict = new HybridDictionary(10);
myDict.Add("A", "Apple");
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");
foreach (DictionaryEntry de in myDict)
Console.WriteLine(de.Key + " " + de.Value);
}
}
|
Output:
B Banana
a Air
A Apple
d Dolphin
C Cat
E Elephant
F Fish
D Dog
Example 2:
CSHARP
using System;
using System.Collections;
using System.Collections.Specialized;
class GFG {
public static void Main()
{
HybridDictionary myDict = new HybridDictionary(10);
myDict.Add("k1", "v1");
myDict.Add("K1", "v1");
myDict.Add("k2", "v2");
myDict.Add("K2", "v2");
myDict.Add("k3", "v3");
myDict.Add("K3", "v3");
foreach (DictionaryEntry de in myDict)
Console.WriteLine(de.Key + " " + de.Value);
}
}
|
Output:
k3 v3
K3 v3
k2 v2
K2 v2
k1 v1
K1 v1
Note:
- If the initial size of the collection is greater than the optimal size for a ListDictionary, the collection is stored in a Hashtable to avoid the overhead of copying elements from the ListDictionary to the Hashtable.
- By default, the collection is case-sensitive.
- Every key in a HybridDictionary must be unique.
- This constructor is an O(n) operation, where n is initialSize.
