This should help get you started. It is an event handler that is wired to a 'Format code block' button. The handler shors how to get the selected text and apply basic formatting to it. If you want to work with all text in the box, then simply set the TextRange accordingly.

/// <summary>
/// Formats code blocks.
/// </summary>
private void OnCodeBlockClick(object sender, RoutedEventArgs e)
{
    var selection = TextBox.Selection;
    var textRange = new TextRange(selection.Start, selection.End);
    textRange.ApplyPropertyValue(TextElement.FontFamilyProperty, "Consolas");
    textRange.ApplyPropertyValue(TextElement.FontSizeProperty, 10D );
    textRange.ApplyPropertyValue(TextElement.BackgroundProperty, "LightSteelBlue");
}
