Getting index of the specified value in a SortedList object in C#

To get index of the specified value in 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 value 7 = "+list1.IndexOfValue(7));
      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 value Books = "+list2.IndexOfValue("Books"));
   }
}

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 value 7 = 5
SortedList2 elements...
A Accessories
B Books
C Smart Wearable Tech
D Home Appliances
Index at value Books = 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 value Marketing = "+list.IndexOfValue("Marketing"));
      Console.WriteLine("Index at value Purchase = "+list.IndexOfValue("Purchase"));
      Console.WriteLine("Index at value Sales = "+list.IndexOfValue("Sales"));
      Console.WriteLine("Index at value IT = "+list.IndexOfValue("IT"));
      Console.WriteLine("Index at value Operations = "+list.IndexOfValue("Operations"));
   }
}

Output

This will produce the following output −

SortedList elements...
Five Operations
Four Purchase
One Finance
Six IT
Three Sales
Two Marketing
Index at value Marketing = 5
Index at value Purchase = 1
Index at value Sales = 4
Index at value IT = 3
Index at value Operations = 0
