C# | Check if HybridDictionary has fixed size

Last Updated : 01 Feb, 2019

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.
