C# | Check if HybridDictionary has fixed size

HybridDictionary.IsFixedSize property is used to get a value that indicates whether the HybridDictionary has a fixed size or not.

Syntax:

public bool IsFixedSize { get; }

Return Value: This property always returns false.

Below are the programs to illustrate the use of HybridDictionary.IsFixedSize property:

Example 1:

// C# code to check whether the
// HybridDictionary has a fixed size.
using System;
using System.Collections;
using System.Collections.Specialized;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a HybridDictionary named myDict
        HybridDictionary myDict = new HybridDictionary();

        // Adding key/value pairs in myDict
        myDict.Add("A", "Apple");
        myDict.Add("B", "Banana");
        myDict.Add("C", "Cat");
        myDict.Add("D", "Dog");
        myDict.Add("E", "Elephant");
        myDict.Add("F", "Fish");

        // To check whether the HybridDictionary
        // has a fixed size.
        Console.WriteLine(myDict.IsFixedSize);
    }
}

Output:

False

Example 2:

// C# code to check whether the
// HybridDictionary has a fixed size.
using System;
using System.Collections;
using System.Collections.Specialized;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a HybridDictionary named myDict
        HybridDictionary myDict = new HybridDictionary();

        // Adding key/value pairs in myDict
        myDict.Add("key1", "value1");
        myDict.Add("key2", "value2");
        myDict.Add("key3", "value3");
        myDict.Add("key4", "value4");

        // To check whether the HybridDictionary
        // has a fixed size.
        Console.WriteLine(myDict.IsFixedSize);
    }
}

Output:

False

Note:

• A collection with a fixed size does not allow the addition or removal of elements after the collection is created, but it allows the modification of existing elements.
• Retrieving the value of this property is an O(1) operation.
