LINQ is the best feature in C#. If you’re interested in writing more expressive code to work with collections, this course is for you. In this course, you will learn about what LINQ is and what lambda expressions are. You will learn the most common LINQ methods and some common pitfalls to avoid when using LINQ. You will also write your first methods using LINQ and use LINQ to refactor some common constructs.

Getting Started with LINQ in C#

## How to choose and leave elements from the collection

With the `First` and `FirstOrDefault` methods, we choose only the first element of a collection. The `Take` method returns a new collection with the first contiguous elements of a collection. The `First` method is equivalent to `Take(1)`.

But, what if we want to leave out the first elements of a collection? We can use the `Skip` method. It returns a new collection without its first elements.

Let's see the `Take` and `Skip` methods in action.
