Console.WriteLine("{0}: {1}", ci.ToString(), d.ToString("D"));

Cultures in action
To see all cultures in action, you can use a sample Windows Presentation Foundation (WPF) application
that lists all cultures and demonstrates different characteristics of culture properties. Figure 22-4 shows the
user interface of the application in the Visual Studio 2010 WPF Designer.
figure 22-4
During initialization of the application, all available cultures are added to the tree view control that is
placed on the left side of the application. This initialization happens in the method AddCulturesToTree(),
which is called in the constructor of the Window class CultureDemoWindow:
public CultureDemoWindow()
{
InitializeComponent();
}
AddCulturesToTree();
code snippet CultureDemo/MainWindow.xaml.cs
In the method AddCulturesToTree(), you get all cultures from the static method CultureInfo
.GetCultures(). Passing CultureTypes.AllCultures to this method returns an unsorted array of all
available cultures. The array is sorted using a Lambda expression that is passed to the Comparison delegate
of the second argument of the Array.Sort() method. Next, in the foreach loop, every single culture is
added to the tree view. A TreeViewItem object is created for every single culture because the WPF TreeView
