How to binding to textblock's inlines?

[mcguu2020]

<TextBlock IsTextSelectionEnabled="True" SelectionHighlightColor="Green" FontFamily="Arial">
    <Run Foreground="Blue" FontWeight="Light" Text="This text demonstrates "></Run>
    <Span FontWeight="SemiBold">
        <Run FontStyle="Italic">the use of inlines </Run>
        <Run Foreground="Red">with formatting.</Run>
    </Span>
</TextBlock>

I want to make this in a listview and the inlines is binding to a dynamic inline.

<TextBlock IsTextSelectionEnabled="True" SelectionHightlightColor="Green" FontFamily="Arial" Inlines="{Binding Inline}"/>
Inline is a InlineCollection

public InlineCollection Inline
{
     get
    {
          var run =new Run(){Text="This text demonstrates"};
          var run1=new Run(){Text="the use of inlines"};
          var inlines=new InlineCollection();
         inlines.Append(run);
         inlines.Append(run1);
        return inlines.
    }
}

but the InlineCollection is not bindable.
