Chapter 4: Generics
Here is that same code using a System.Collections.Generic.List object:
public static void UseGenericList( )
{
// Create and populate a List.
List<int> numbers = new List<int>( );
numbers.Add(1);
numbers.Add(2);
// Display all integers in the ArrayList.
foreach (int i in numbers)
{
Console.WriteLine(i);
}
numbers.Clear( );
}
Discussion
Since ArrayLists are used in almost all applications, it is a good place to start to
enhance the performance of your application. For simple implementations of the
ArrayList in your application, this substitution should be quite easy. However, there
are some things to watch out for. For example, the generic
List class does not imple-
ment the
ICloneable interface while the ArrayList class does.
Table 4-1 shows the equivalent members that are implemented in both classes.
