What are some examples of using LINQ Select in C#?

Can you give me some examples of using LINQ Select in C#?

Sure! LINQ Select is used to project each element of a sequence into a new form. For example, if you have a list of integers and you want to square each number, you can do it like this:

var numbers = new List<int> { 1, 2, 3, 4, 5 };
var squares = numbers.Select(n => n * n);

That's great! Can you show me how to select specific properties from a list of objects?

Absolutely! If you have a list of objects, say a list of Person objects, you can select specific properties like this:

var people = new List<Person> {
    new Person { Name = "Alice", Age = 30 },
    new Person { Name = "Bob", Age = 25 }
};
var names = people.Select(p => p.Name);

What if I want to filter the results while selecting?

You can combine Where with Select to filter the results. For example:

var adults = people.Where(p => p.Age >= 18).Select(p => p.Name);

Can you explain how to use LINQ Select with anonymous types?

Certainly! You can create anonymous types in your select statement like this:

var selected = people.Select(p => new { p.Name, IsAdult = p.Age >= 18 });
