What are some examples of using LINQ in C#?

LINQ (Language Integrated Query) in C# allows you to query collections in a concise way. For example, you can use LINQ to filter a list of numbers.

Can you show me a specific example of filtering a list?

Sure! Here's an 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 list of even numbers: 2, 4, 6.

What about sorting a list using LINQ?

You can sort a list using the OrderBy method. For example:

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

This will sort the numbers in ascending order.

Are there any other LINQ methods I should know about?

Yes! Some other useful LINQ methods include Select, FirstOrDefault, and GroupBy. Each serves different purposes for querying data.
