Adding a line to a textblock programmatically

Question

I know how to add a control to the canvas/grid/layout- simply by calling canvas.Childern.Add(). However, when I want to embed something inside a textblock, I can't seem to find the method for it. A textblock doesn't contain a Add method or anything, so I'm at a bit of a lost.

The XAML I'm trying to turn into C# is:

<TextBlock x:Name="textBlock">
    <Line X1="0" Y1="0" X2="100" Y2="0" Stroke="Black" StrokeThickness="4" x:Name="line1"/>
    <TextBlock Text="Hello there!" VerticalAlignment="Center" HorizontalAlignment="Center" x:Name="innerTextBlock" />
    <Line X1="0" Y1="0" X2="100" Y2="0" Stroke="Black" StrokeThickness="4" x:Name="line2"/>
</TextBlock>

EDIT: I think the best way to do it (besides the answer) is to simply create a WPF User control and reference that.

Answer 1

You have to use inlines property (as stated before) so to reproduce your xaml it is enough to do the following (where LayoutRoot is the name of your parent control):

        var t = new TextBlock();
        t.Inlines.Add(new Line { X1 = 0, Y1 = 0, X2 = 100, Y2 = 0, Stroke = new SolidColorBrush(Colors.Black), StrokeThickness = 4.0 });
        t.Inlines.Add("Hello there!");
        t.Inlines.Add(new Line { X1 = 0, Y1 = 0, X2 = 100, Y2 = 0, Stroke =  new SolidColorBrush(Colors.Black),StrokeThickness = 4.0});
        LayoutRoot.Children.Add(t);
