Obtaining Counts Using Enumerable

Using these query operators (and auxiliary members of the System.Linq.Enumerable type), you

are able to build very expressive query expressions in a strongly typed manner. To invoke the

Enumerable extension methods, you typically wrap the LINQ expression within parentheses to cast

the result to an IEnumerable-compatible object to invoke the Enumerable extension method.

You have already done so during our examination of immediate execution; however, here is

another example that allows you to discover the number of items returned by a LINQ query:

static void GetCount()

{

string[] currentVideoGames = {"Morrowind", "BioShock",

"Half Life 2: Episode 1", "The Darkness",

"Daxter", "System Shock 2"};
