C# | Get an enumerator that iterates through the SortedList Last Updated : 01 Feb, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report SortedList.GetEnumerator Method is used to an IDictionaryEnumerator object that iterates through a SortedList object. Syntax: public virtual System.Collections.IDictionaryEnumerator GetEnumerator (); Return Value: This method returns an IDictionaryEnumerator object for the SortedList object. Below programs illustrate the use of above discussed method: Example 1: CSharp // C# code to get IDictionaryEnumerator object // that iterates through a SortedList object using System; using System.Collections; class Geeks { // Main Method public static void Main(String[] args) { // Creating a SortedList of integers SortedList mylist = new SortedList(); // Adding elements to SortedList mylist.Add("1", "C++"); mylist.Add("2", "Java"); mylist.Add("3", "DSA"); mylist.Add("4", "Python"); mylist.Add("5", "C#"); // To get an IDictionaryEnumerator // for the SortedList IDictionaryEnumerator myEnumerator = mylist.GetEnumerator(); // If MoveNext passes the end of the // collection, the enumerator is positioned // after the last element in the collection // and MoveNext returns false. while (myEnumerator.MoveNext()) Console.WriteLine(myEnumerator.Key + " --> " + myEnumerator.Value); } } Output: 1 --> C++ 2 --> Java 3 --> DSA 4 --> Python 5 --> C# Example 2: CSharp // C# code to get IDictionaryEnumerator object // that iterates through a SortedList object using System; using System.Collections; class Geeks { // Main Method public static void Main(String[] args) { // Creating a SortedList of integers SortedList mylist = new SortedList(); // Adding elements to SortedList mylist.Add("Australia", "Canberra"); mylist.Add("Belgium", "Brussels"); mylist.Add("Netherlands", "Amsterdam"); mylist.Add("China", "Beijing"); mylist.Add("Russia", "Moscow"); mylist.Add("India", "New Delhi"); // To get an IDictionaryEnumerator // for the SortedList IDictionaryEnumerator myEnumerator = mylist.GetEnumerator(); // If MoveNext passes the end of the // collection, the enumerator is positioned // after the last element in the collection // and MoveNext returns false. while (myEnumerator.MoveNext()) Console.WriteLine(myEnumerator.Key + " --> " + myEnumerator.Value); } } Output: Australia --> Canberra Belgium --> Brussels China --> Beijing India --> New Delhi Netherlands --> Amsterdam Russia --> Moscow Note: The foreach statement of the C# language hides the complexity of the enumerators. Therefore, using foreach is recommended, instead of directly manipulating the enumerator. Enumerators can be used to read the data in the collection, but they cannot be used to modify the underlying collection. Current returns the same object until either MoveNext or Reset is called. MoveNext sets Current to the next element. An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is irrecoverably invalidated and its behavior is undefined. This method is an O(1) operation.
