Getting the key at the specified index of a SortedList object in C#

CsharpServer Side ProgrammingProgramming

To get the key at the specified index of a SortedList object, the code is as follows −

Example

 Live Demo

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.Write("Index at key Five = "+list1.IndexOfKey("Five"));
      Console.Write("
Key at index 2 = "+list1.GetKey(2));       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.Write("Index at key B = "+list2.IndexOfKey("B"));    } }

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
Index at key Five = 1
Key at index 2 = Four
SortedList2 elements...
A Accessories
B Books
C Smart Wearable Tech
D Home Appliances
Index at key B = 1

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args) {
      SortedList list = new SortedList();
      list.Add("One", "Finance");
      list.Add("Two", "Marketing");
      list.Add("Three", "Sales");
      list.Add("Four", "Purchase");
      list.Add("Five", "Operations");
      list.Add("Six", "IT");
      Console.WriteLine("SortedList elements...");
      foreach(DictionaryEntry d in list) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("
Index at key One = "+list.IndexOfKey("One"));       Console.Write("
Key at index 5 = "+list.GetKey(5));    } }

Output

This will produce the following output −

SortedList elements...
Five Operations
Four Purchase
One Finance
Six IT
Three Sales
Two Marketing
Index at key One = 2
Key at index 5 = Two
