In C# and WPF, can you bind an element of an array to an objects property?

Question

For example, is it possible to bind a Textblock\'s Text property to an element Name[2] of type String?

Answer 1

I've added a button in xaml and subscribed "click" event.

Here is C# code.

public partial class MainWindow : Window, INotifyPropertyChanged
{
    private Array array1 = new[] { "test1", "test2", "test3" };
    public Array Array1 { get { return array1; } }


    public string string1 = "string";
    public string String1
    {
        get { return string1; }
        set
        {
            string1 = value;
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs("String1"));
        }
    }

    public MainWindow()
    {
        InitializeComponent();
        this.DataContext = this;

    }

    public event PropertyChangedEventHandler PropertyChanged;

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        String1 = DateTime.Now.ToString();
        array1.SetValue("another test", 0); 
        PropertyChanged(this, new PropertyChangedEventArgs("Array1"));
    }
}
