, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted(), then it may run slower because the database could return far more veri than is actually needed, and we waste cycles doing the filtering in the client.

are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable object kakım a runtime-traversable abstract syntax tree that can be understood by the given query provider (for the most part, you dirilik't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

Şimdiye derece .Kupkuru ile infaz vüruttirenler IENumarable ve IENumerator interface strüktürlarını birgani yerde gördük yahut farkında olmadan çok kullandık amma ne hizmete yarıyor niye bu fasıla yüzlere ihtiyaç duyulur nerelerde kullanabilirim kabil sorulara bu makalemizde arsa vereceğiz.
