The term "LINQ to Objects" refers to the use of LINQ queries with any IEnumerable or IEnumerable<T> collection directly, without the use of an intermediate LINQ provider or API such as LINQ to SQL or LINQ to XML.

For example, say that myCats is a list of Cat objects. Then you can pick your favorite cat by using:

Cat myFavorite = myCats.Single(c => c.Score == myCats.Max(x => x.Score));

To get an alphabetical listing of your cats, use this:

var listing = myCats.OrderBy(c => c.Name);

To get all cats that have caught more than 20 mice, use the following:

var champions = myCats.Where(c => c.MiceCaught.Count > 20);

You can also use a more SQL-like syntax:

var champions = from cat in myCats where cat.MiceCaught.Count > 20 select cat;

LINQ to Objects thus uses the same familiar syntax as the other LINQ implementations such as LINQ to Entities and LINQ to SQL.
