The LinqOverArray project can be found under the Chapter 14 subdirectory.

LINQ and Generic Collections

Beyond pulling results from a simple array of data, LINQ query expressions can also manipulate

data within members of the System.Collections.Generic namespace, such as the List type.

Create a new .NET 3.5 Console Application project named LinqOverCustomObjects, and define a

basic Car type that maintains a current speed, color, make, and pet name (public fields are used to

easily set the string fields to empty text. Feel free to make use of automatic properties and class

constructors if you wish):

class Car

{

public string PetName = string.Empty;

public string Color = string.Empty;

public int Speed;

public string Make = string.Empty;

}

Now, within your Main() method, define a local List variable of type Car, and make use of

the new object initialization syntax (see Chapter 13) to fill the list with a handful of new Car objects:

C H A P T E R   1 4
