While the syntax of these queries is simple enough, remember that you are hitting a database each time you apply a LINQ query to the object context! Recall that when you wish to obtain an independent copy of data, which can be the target of new LINQ queries, you want to use immediate execution with the ToList<T>(), ToArray<T>() or ToDictionary<K,V>() extension methods (among others). Here is an update of the previous method, which performs the equivalent of a SELECT *, caches the entities as an array, and manipulates the array data using LINQ to Objects: using (AutoLotEntities context = new AutoLotEntities()) { // Get all data from the Inventory table. // could also write: // var allData = (from item in context.Cars select item).ToArray(); var allData = context.Cars.ToArray(); // Get a projection of new data. var colorsMakes = from item in allData select new { item.Color, item.Make }; // Get only items where CarID < 1000 var idsLessThan1000 = from item in allData where item.CarID < 1000 select item; } Working with LINQ to Entities is much more enticing when your EDM contains multiple related tables. You ll see some example that illustrate this in a moment; however, let s wrap up this current example by looking at two other ways you can interact with your object context.

Later in this chapter (in the section Anonymous Profiles ), you ll also learn how the anonymous identification feature lets you temporarily store profile information for users who haven t logged in.

To be sure, you will be querying and ObjectSet<T> with LINQ a majority of the time. The entity client will break down your LINQ query into a fitting SQL statement, passing it onto the database for processing. However, you can use Entity SQL if you wish to have more control over how the query is formatted. Entity SQL is a SQL-like query language that can be applied to entities. While the format of an Entity SQL statement is similar to a traditional SQL statement, it is not identical. Entity SQL has a unique syntax because the entities receive the query, not the physical database. Like a LINQ to Entities query, an Entity SQL query is used to pass a real SQL query to the database. This chapter will not dive into the details of building Entity SQL commands, so please consult the .NET Framework 4.0 SDK documentation if you want more information. However, one example might be helpful. Consider the following method, which builds an Entity SQL statement that finds all black cars in the ObjectSet<Car> collection: private static void FunWithEntitySQL() { using (AutoLotEntities context = new AutoLotEntities()) { // Build a string containing Entity SQL syntax. string query = "SELECT VALUE car FROM AutoLotEntities.Cars " + "AS car WHERE car.Color='black'"; // Now build a ObjectQuery<T> based on the string. var blackCars = context.CreateQuery<Car>(query);

Profiles are a natural competitor with custom data components of the kind you saw in 8. Clearly, data components are far more flexible. They allow you not only to maintain user-specific information but also to store other types of information and perform more complex business tasks. For example, an e-commerce website could realistically use profiles to maintain customer address information (with the limitations discussed in the previous section). However, you wouldn t

foreach (var item in blackCars) { Console.WriteLine(item); } } } Notice that you pass in the formatted Entity SQL statement as an argument to the CreateQuery<T> method of your object context.

use a profile to store information about previous orders. Not only is it far too much information to store efficiently, it s also awkward to manipulate.
