Chapter review

For review, the complete version of the Default.aspx.cs file for this chapter, including comments, is shown in the following code block:

//using is a directive
//System is a name space
//name space is a collection of features that our needs to run
using System;
//public means accessible anywhere
//partial means this class is split over multiple files
//class is a keyword and think of it as the outermost level of grouping
//:System.Web.UI.Page means our page inherits the features of a Page
public partial class _Default : System.Web.UI.Page
{
    protected void Button1_Click(object sender, EventArgs e)
    {
        //in each case below, GenericsClass<...> works equally well with
        //integers, doubles and decimals, among others
        GenericsClass<int> ints = new GenericsClass<int>(new int[] { 1, 2, 3, 4, 5 });
        sampLabel.Text = ints.DisplayValues();
        GenericsClass<double> dubs = new GenericsClass&lt;double>(new double[] { 1.0, -2.3, 3, 4, 5 });
        sampLabel.Text += ints.DisplayValues();
        GenericsClass<decimal> decs = new GenericsClass<decimal>(new decimal[] { 1, 2.0M, 3, 4, 5.79M });
        sampLabel.Text += decs.DisplayValues();
    }
