In WPF Textblock with multiple runs how do i apply a style to a particular one?

How do I apply a style not on the whole textblock, but only on the first run (the Bold)?

I want to apply the style "XXXFontName-Bold" on the Bold Run AND the style "XXXFontName-Thin" on the rest.

        // add button
        Button btn = new Button();
        TextBlock contextText = new TextBlock();
        contextText.Inlines.Add(new Bold(new Run(label.Substring(0,1))));
        contextText.Inlines.Add(new Style());     <===== OBVIOUS ERROR HERE
        contextText.Inlines.Add(label.Substring(1));
        contextText.FontSize = 25;
        contextText.Style = FindResource("XXXFontName-Thin") as Style;
        btn.Content = contextText;

3 Example Styles, Example to set runs in XAML with the styles and new lines and also how to set them in the code behind in your button

Your code behind:

public MainWindow()
{
    InitializeComponent();

    Button btn = new Button();
    TextBlock contextText = new TextBlock();
    var newRun = new Run("BoldGreenRunStyle");
    newRun.Style = FindResource("BoldGreenRunStyle") as Style;
    contextText.Inlines.Add(newRun);

    newRun = new Run("ItalicRedRunStyle");
    newRun.Style = FindResource("ItalicRedRunStyle") as Style;
    contextText.Inlines.Add(newRun);

    newRun = new Run("ThinPurpleRunStyle");
    newRun.Style = FindResource("ThinPurpleRunStyle") as Style;
    contextText.Inlines.Add(newRun);

    btn.Content = contextText;

    Container.Children.Add(btn);
}

Your XAML

    <Window.Resources>
        <Style TargetType="Run" x:Key="BoldGreenRunStyle">
            <Setter Property="Foreground" Value="Green"></Setter>
            <Setter Property="FontWeight" Value="Bold"></Setter>
        </Style>
        <Style TargetType="Run" x:Key="ItalicRedRunStyle">
            <Setter Property="Foreground" Value="Red"></Setter>
            <Setter Property="FontWeight" Value="Normal"></Setter>
            <Setter Property="FontStyle" Value="Italic"></Setter>
        </Style>
        <Style TargetType="Run" x:Key="ThinPurpleRunStyle">
            <Setter Property="Foreground" Value="Purple"></Setter>
            <Setter Property="FontWeight" Value="Thin"></Setter>
        </Style>
    </Window.Resources>
    <StackPanel x:Name="Container">
        <Label Content="From XAML"></Label>
        <TextBlock>
            <TextBlock.Inlines>
                <Run Style="{StaticResource BoldGreenRunStyle}">BoldGreenRunStyle</Run>
                <LineBreak/>
                <Run Style="{StaticResource ItalicRedRunStyle}">ItalicRedRunStyle</Run>
                <LineBreak/>
                <Run Style="{StaticResource ThinPurpleRunStyle}">ThinPurpleRunStyle</Run>
                <LineBreak/>
            </TextBlock.Inlines>
        </TextBlock>
    </StackPanel>
