C# program to get the index of the specified key in a SortedList (Example of IndexOfKey() Method)

Program:

The source code to get the index of the specified key in a SortedList is given below. The given program is compiled and executed successfully.

using System;
using System.Collections;

class SortedListEx
{
    //Entry point of Program
    static public void Main()
    {
        //Creation of SortedList object
        SortedList list = new SortedList();
        
        int index = 0;


        //Add elements to SortedList 
        list.Add(101, "India");
        list.Add(105, "America");
        list.Add(102, "Austrelia");
        list.Add(103, "Africa");
        list.Add(104, "Canada");
                
        Console.WriteLine("Index of keys:");
        foreach (int key in list.GetKeyList())
        {
            index = list.IndexOfKey(key);
            Console.WriteLine("Key "+key+" at index: "+index);
        }

    }
}

Output:

Index of keys:
Key 101 at index: 0
Key 102 at index: 1
Key 103 at index: 2
Key 104 at index: 3
Key 105 at index: 4
