WPF Inlines.add: prevent linebreak - wpf

Question

I work in WPF project and I'm new in this area.
I need to add link programatically.
Before and after the link I want to add some words.
After the words before link I put linebreak.
But the words after the link need to not have line break but continue in the same row.
But I got linebreak after each element that I add by 'inlines.add'.
Any solution?
Here is my code:
TextBlock tb = new TextBlock();
tb.Inlines.Add("this is my prefix
");
Hyperlink h = new Hyperlink();
h.NavigateUri = new System.Uri(helpLinkURL);
h.Inlines.Add("here is link text");
h.RequestNavigate += Hyperlink_RequestNavigate;
tb.Inlines.Add(h);
tb.Inlines.Add("this is my suffix");
helpLinkPlaceHolder.Inlines.Add(tb);
I get:
this is my prefix
here is link text
this is my suffix
And this is what I want to get:
this is my prefix
here is link text this is my suffix

Answer 1

Try to use Run instead of TextBlock. It has propierties and functions that allows you to do this.

Answer 2

This way you can do it in code behind:
var hyperlink = new Hyperlink(new Run("here is link text"))
{
NavigateUri = new Uri("https://google.com")
};
hyperlink.RequestNavigate += Hyperlink_RequestNavigate;
var textblock = new TextBlock
{
Inlines =
{
new Run("this is my prefix"),
new LineBreak(),
hyperlink,
new Run(" this is my suffix")
}
};
placeholderContentControl.Content = textblock;
placeholderContentControl is of type <ContentControl>
How to do it in XAML:
<Grid>
<TextBlock Grid.Row="0">
this is my prefix
<LineBreak />
<Hyperlink NavigateUri="https://google.com" RequestNavigate="Hyperlink_RequestNavigate">
here is link text
</Hyperlink>
this is my suffix
</TextBlock>
</Grid>
