C# | Check if a SortedList object has a fixed size Last Updated : 01 Feb, 2019 Comments Improve Suggest changes Like Article Like Report SortedList class is a collection of (key, value) pairs which are sorted according to keys. Those pairs can be accessible by key and as well as by index(zero-based indexing). This comes under System.Collections namespace. SortedList.IsFixedSize property is used to check whether a SortedList object has a fixed size or not. Properties of SortedList: Internally the object of SortedList maintain two arrays. The first array is used to store the elements of the list i.e. keys and the second one is used to store the associated values. A key cannot be null, but value can be. As SortedList uses sorting, it makes it slower in comparison to Hashtable. The capacity of a SortedList can be dynamically increased through reallocation. The keys in the SortedList cannot be duplicated but values can be. The SortedList can be sorted according to the keys using the IComparer(Either in ascending or descending order). Syntax: public virtual bool IsFixedSize { get; } Return Value: This property returns True if the SortedList object has a fixed size, otherwise it returns False. The default value of this property is False. Example: CSHARP // C# code to check if a SortedList // object has a fixed size using System; using System.Collections; class GFG { // Driver code public static void Main() { // Creating an SortedList SortedList mySortedList = new SortedList(); // Adding elements to SortedList mySortedList.Add("1", "one"); mySortedList.Add("2", "two"); mySortedList.Add("3", "three"); mySortedList.Add("4", "four"); mySortedList.Add("5", "five"); // Checking if a SortedList // object has a fixed size Console.WriteLine(mySortedList.IsFixedSize); } } 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.
