How do I use LINQ Select queries in C#?

You can use LINQ Select queries to project each element of a collection into a new form. For example, if you have a list of objects, you can select specific properties.

Can you show me a code example?

Sure! Here's a simple example:

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

This will give you a collection of squares of the numbers.

What if I want to select multiple properties from a list of objects?

You can use an anonymous type to select multiple properties. For example:

var people = new List<Person> { ... };
var selected = people.Select(p => new { p.Name, p.Age });

This will create a new collection with just the Name and Age properties.
