Getting the list of keys of a SortedList object in C#
To get the list of keys of a SortedList object, the code is as follows −
Example
using System; using System.Collections; public class Demo { public static void Main(String[] args) { SortedList list1 = new SortedList(); list1.Add("One", 1); list1.Add("Two ", 2); list1.Add("Three ", 3); list1.Add("Four", 4); list1.Add("Five", 5); list1.Add("Six", 6); list1.Add("Seven ", 7); list1.Add("Eight ", 8); list1.Add("Nine", 9); list1.Add("Ten", 10); Console.WriteLine("SortedList1 elements..."); foreach(DictionaryEntry d in list1) { Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("
List of keys...SortedList1"); IList list = list1.GetKeyList(); foreach(string res in list) Console.WriteLine(res); SortedList list2 = new SortedList(); list2.Add("A", "Accessories"); list2.Add("B", "Books"); list2.Add("C", "Smart Wearable Tech"); list2.Add("D", "Home Appliances"); Console.WriteLine("
SortedList2 elements..."); foreach(DictionaryEntry d in list2) { Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("
List of keys...SortedList2"); list = list2.GetKeyList(); foreach(string res in list) Console.WriteLine(res); } }
Output
This will produce the following output −
SortedList1 elements... Eight 8 Five 5 Four 4 Nine 9 One 1 Seven 7 Six 6 Ten 10 Three 3 Two 2 List of keys...SortedList1 Eight Five Four Nine One Seven Six Ten Three Two SortedList2 elements... A Accessories B Books C Smart Wearable Tech D Home Appliances List of keys...SortedList2 A B C D
Example
Let us see another example −
using System; using System.Collections; public class Demo { public static void Main(String[] args) { SortedList list = new SortedList(); list.Add("One", 1); list.Add("Two ", 2); list.Add("Three ", 3); list.Add("Four", 4); list.Add("Five", 5); Console.WriteLine("SortedList elements..."); foreach(DictionaryEntry d in list) { Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("
List of keys...SortedList"); IList col = list.GetKeyList(); foreach(string res in col) Console.WriteLine(res); } }
Output
This will produce the following output −
SortedList elements... Five 5 Four 4 One 1 Three 3 Two 2 List of keys...SortedList Five Four One Three Two
