CsharpServer Side ProgrammingProgramming

To get or set the element at specified index in Collection, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.ObjectModel;
public class Demo {
   public static void Main() {
      Collection<string> col = new Collection<string>();
      col.Add("Laptop");
      col.Add("Desktop");
      col.Add("Notebook");
      col.Add("Ultrabook");
      col.Add("Tablet");
      col.Add("Headphone");
      col.Add("Speaker");
      Console.WriteLine("Elements in Collection...");
      foreach(string str in col) {
         Console.WriteLine(str);
      }
      Console.WriteLine("Element at index 3 = " + col[3]);
      Console.WriteLine("Element at index 4 = " + col[4]);
   }
}

Output

This will produce the following output −

Elements in Collection...
Laptop
Desktop

Ultrabook
Tablet
Headphone
Speaker
Element at index 3 = Ultrabook
Element at index 4 = Tablet

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.ObjectModel;
public class Demo {
   public static void Main() {
      Collection<string> col = new Collection<string>();
      col.Add("Laptop");
      col.Add("Desktop");
      col.Add("Notebook");
      col.Add("Ultrabook");
      col.Add("Tablet");
      col.Add("Headphone");
      col.Add("Speaker");
      Console.WriteLine("Elements in Collection...");
      foreach(string str in col) {
         Console.WriteLine(str);
      }
      Console.WriteLine("Element at index 3 = " + col[3]);
      col[3] = "SSD";
      Console.WriteLine("Element at index 3 (Updated) = " + col[3]);
   }
}

Output

This will produce the following output −

Elements in Collection...
