Standard Query Operators

LINQ is built upon the use of standard query operators, which are methods that operate on

sequences such as collections that implement IEnumerable or IQueryable. As discussed previously,

when the C# compiler encounters a query expression, it converts the expression into a series or

chain of calls to those extension methods that implement the behavior.

There are two benefits to this approach. One is that you can generally perform the same

actions as a LINQ query expression by calling the extension methods directly. The resulting code is

not as easy to read as code with query expressions. However, there may be times when you need

functionality from the extension methods and a complete query expression may be overkill.
