C# | Getting the value at the specified index of a SortedList object

  • Last Updated : 01 Feb, 2019

SortedList.GetByIndex(Int32) Method is used to get the value at the specified index of a SortedList object.

Syntax:

public virtual object GetByIndex (int index);

Here index is the zero-based index of the value to get.

Return Value: It returns the value at the specified index of the SortedList object.

Exception: This method will throw ArgumentOutOfRangeException if the index is outside the range of valid indexes for the SortedList object.



Below programs illustrate the use of above-discussed method:

Example 1:




// C# code to get the value at the specified
// index of 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#");
  
        // getting the indexing and
        // store into a variable
        int i = 4;
  
        // getting the value at index 4
        Console.WriteLine("Value at index {0} is {1}",
                          i, mylist.GetByIndex(i));
    }
}

Output:

Value at index 4 is C#

Example 2:




// C# code to get the value at the specified
// index of 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("First", "Ram");
        mylist.Add("Second", "Shyam");
        mylist.Add("Third", "Mohit");
        mylist.Add("Fourth", "Rohit");
        mylist.Add("Fifth", "Manish");
  
        // getting the indexing and
        // store into a variable
        // it will give error as
        // index is out of range
        int i = 7;
  
        // getting the value at index 7
        Console.WriteLine("Value at index {0} is {1}",
                          i, mylist.GetByIndex(i));
    }
}

Runtime Error:

Unhandled Exception:
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
