Question

public partial class Window2 : Window
{
    int margin = 200;
    public Window2()
    {
        this.InitializeComponent();

        for (int i = 1; i <= 5; i++)
        {
            TextBlock DynamicLine = new TextBlock();
            DynamicLine.Name = "lbl_DynamicLine" + i;
            DynamicLine.Width = 600;
            DynamicLine.Height = 20;
            DynamicLine.Text =i+"Dynamic TextBlock";
            DynamicLine.Margin = new Thickness(50, margin, 0, 0);
            margin = margin + 20;

            LayoutRoot.Children.Add(DynamicLine);

        }
    }
}

    int margin = 200;
    TextBlock DynamicLine;
    public Window2()
    {
        this.InitializeComponent();

        for (int i = 1; i <= 5; i++)
        {
            DynamicLine = new TextBlock();
            DynamicLine.Name = "lbl_DynamicLine" + i;
            RegisterName(DynamicLine.Name, DynamicLine);
            DynamicLine.Width = 600;
            DynamicLine.Height = 20;
            DynamicLine.Text =i+"Dynamic TextBlock";
            DynamicLine.Margin = new Thickness(50, margin, 0, 0);
            margin = margin + 20;

            LayoutRoot.Children.Add(DynamicLine);             

        }

        for (int i = 1; i <= 5; i++)
        {
            DynamicLine = (TextBlock)this.FindName("lbl_DynamicLine" + i);
            LayoutRoot.Children.Remove(DynamicLine);
        }

    }
}
