In LINQ, you can write queries in two ways: in query syntax and method syntax.

Query syntax looks like a multi-line sentence. If you’ve used SQL, you might see some similarities:

var longLoudHeroes = from h in heroes
  where h.Length > 6
  select h.ToUpper();

Method syntax looks like plain old C#. We make method calls on the collection we are querying:

var longHeroes = heroes.Where(h => h.Length > 6);
var longLoudHeroes = longHeroes.Select(h => h.ToUpper());

In LINQ, we see where/Where() and select/Select() show up as both keywords and method calls. To cover both cases, they’re generally called operators.

Every developer has a personal preference between syntaxes, but you should be able to read both. In this lesson we’ll start with query syntax then move on to method.
