Working with the ArrayList Type

To illustrate working with these collection types, create a new Console Application project named

CollectionTypes. Our ArrayList will maintain a set of simple Car objects, defined as follows:

class Car

{

// Public fields for simplicity.

public string PetName;

public int Speed;

// Constructors.

public Car(){}

public Car(string name, int currentSpeed)

{ PetName = name; Speed = currentSpeed;}

}

Next, update your project’s initial C# file to specify you are using the System.Collections

namespace:

using System.Collections;

The ArrayList type is bound to be your most frequently used type in the System.Collections

namespace in that it allows you to dynamically resize the contents at your whim. To illustrate the

basics of this type, ponder the following method to your Program class, which leverages the

ArrayList to manipulate a set of Car objects:

static void ArrayListTest()

{

Console.WriteLine("\n=> ArrayList Test:\n");
