LINQ (Language Integrated Query)

LINQ allows you to query collections and databases using a SQL-like syntax.

LINQ Example

List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
var evenNumbers = from num in numbers
                  where num % 2 == 0
                  select num;

foreach (var num in evenNumbers)
{
    Console.WriteLine(num); // Output: 2, 4
}
      

LINQ with Methods

var evenNumbers = numbers.Where(num => num % 2 == 0);
