Is LINQ to Objects Used?

Question

Does LINQ to Objects request LINQ provider caching for the second time?

Answer 1

LINQ-to-Objects has nothing to cache, which simply uses a series of extension method calls to generate a chain (or graph) of iterators. This is not like LINQ-to-SQL, which must compile a graph into SQL statements before executing it.

Answer 2

No no. Because linq for objects is just extensions that pipe your enumerated to another, enumerated, or executing it immediately. It’s easier to understand how linq works by reading this article .
