LINQ in C#

 LINQ in C#

LINQ (Language Integrated Query) is a feature in C# that allows a program to query data from various data sources such as arrays, collections, databases, etc. using a common syntax. Here's an example code that demonstrates how to use LINQ to query an array:

int[] numbers = { 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);  // prints 2 4

}
