C# | Check if HybridDictionary is read only Last Updated : 01 Feb, 2019 Comments Improve Suggest changes Like Article Like Report HybridDictionary.IsReadOnly property is used to get a value that indicates whether the HybridDictionary is read-only or not. Syntax: public bool IsReadOnly { get; } Return Value: This property always returns false. Below programs illustrate the use of HybridDictionary.IsReadOnly property: Example 1: CSHARP // C# code to check whether the // HybridDictionary is read-only. 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 // is read-only. Console.WriteLine(myDict.IsReadOnly); } } Output: False Example 2: CSHARP // C# code to check whether the // HybridDictionary is read-only. 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("one", "1"); myDict.Add("two", "2"); myDict.Add("three", "3"); myDict.Add("four", "4"); // To check whether the HybridDictionary // is read-only. Console.WriteLine(myDict.IsReadOnly); } } Output: False Note: A collection that is read-only does not allow the addition, removal, or modification of elements after the collection is created. Retrieving the value of this property is an O(1) operation. A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection. Therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.
