How can I use LINQ with collections in C#?

You can use LINQ to query collections like arrays, lists, and dictionaries in C#. Would you like an example?

Yes, please provide an example of filtering a list.

Sure! Here's a simple example:

List<int> numbers = new List<int> { 1, 2, 3, 4, 5, 6 };
var evenNumbers = numbers.Where(n => n % 2 == 0);

This will give you a collection of even numbers.

What if I want to sort the numbers instead?

You can use the OrderBy method. Here's how:

var sortedNumbers = numbers.OrderBy(n => n);

This will sort the numbers in ascending order.

Can I combine filtering and sorting in one query?

Absolutely! You can chain methods like this:

var result = numbers.Where(n => n % 2 == 0).OrderBy(n => n);

This will filter for even numbers and then sort them.
