C# | Check if ListDictionary has a fixed size Last Updated : 01 Feb, 2019 Comments Improve Suggest changes Like Article Like Report ListDictionary.IsFixedSize property is used to get a value indicating whether the ListDictionary has a fixed size or not. Syntax: public bool IsFixedSize { get; } Return Value : This property always returns false. Example: CSHARP // C# code to check if ListDictionary // has a fixed size using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a ListDictionary named myDict ListDictionary myDict = new ListDictionary(); myDict.Add("Australia", "Canberra"); myDict.Add("Belgium", "Brussels"); myDict.Add("Netherlands", "Amsterdam"); myDict.Add("China", "Beijing"); myDict.Add("Russia", "Moscow"); myDict.Add("India", "New Delhi"); // Checking if ListDictionary 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. A collection with a fixed size is simply a collection with a wrapper that prevents adding and removing elements. Therefore, if changes are made to the underlying collection, including the addition or removal of elements, the fixed-size collection reflects those changes. Retrieving the value of this property is an O(1) operation.
