Listusers = new List (); // Populate the users list var userNames = users.Select(u => u.Name);
int[] numbers = { 1, 2, 3, 4, 5 }; var stringNumbers = numbers.Select(n => n.ToString());In this example, the Select method takes a lambda expression that converts each integer element into a string representation by calling the ToString() method. The System.Linq package is the library that contains the Select method. This library provides a variety of extension methods for querying collections and is included with the .NET Framework.
