Sorting and more

Other commonly used extension methods are OrderBy and ThenBy, used for sorting a sequence.

Sorting by a single property using OrderBy

Extension methods can be chained if the previous method returns another sequence, that is, a type that implements the IEnumerable<T> interface.Let's continue working with the current project to explore sorting:

1. In the FilteringUsingWhere method, append a call to OrderBy to the end of the existing query, as shown in the following code:

var query = names
  .Where(name => name.Length > 4)
  .OrderBy(name => name.Length);

Good Practice: Format the LINQ statement so that each extension method call happens on its own line, to make it easier to read.

1. Run the code and note that the names are now sorted by shortest first, as shown in the following output:

Kevin 
Creed 
Dwight 
Angela 
Michael

To put the longest name first, you would use OrderByDescending.
