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#

Which of the following methods is _not_ a new LINQ method?

Which of the following methods is not a new LINQ method?

`[ "Modern Times", "Grave of the Fireflies" ]`

`[ "Grave of the Fireflies", "City Lights" ]`

We have the following list of movies:

```csharp
var movies = new List<Movie>
{
	new Movie("The Lion King", 1994, 8.5f),
	new Movie("Modern Times", 1936, 8.5f),
	new Movie("Grave of the Fireflies", 1988, 8.5f),
	new Movie("City Lights", 1931, 8.5f),
	new Movie("Whiplash", 2014, 8.5f),
	new Movie("Gladiator", 2000, 8.5f),
};
```

What is the expected output of the following LINQ query?

```csharp
var result = movies.Take(^5..3)
	.Select(movie => movie.Name);
```

We have the following list of movies:
<pre><code class="language-csharp">var movies = new List&lt;Movie&gt;
{
	new Movie(&quot;The Lion King&quot;, 1994, 8.5f),
	new Movie(&quot;Modern Times&quot;, 1936, 8.5f),
	new Movie(&quot;Grave of the Fireflies&quot;, 1988, 8.5f),
	new Movie(&quot;City Lights&quot;, 1931, 8.5f),
	new Movie(&quot;Whiplash&quot;, 2014, 8.5f),
	new Movie(&quot;Gladiator&quot;, 2000, 8.5f),
};
</code></pre>
What is the expected output of the following LINQ query?
<pre><code class="language-csharp">var result = movies.Take(^5..3)
	.Select(movie =&gt; movie.Name);
</code></pre>
