c# - ITrextSharp using multiple font styles together. ie Bold, Underlined, italic... etc -

i attempting use itextsharp.dll (not sure version) write dynamic pdf. going great until needed write phrase bold , underlined. appears itextsharp's font class not allow this. allows bold/italic, not bold/underline, italic/ underline, or three. cannot combine underlined other style. seems rather silly not allow font both underlined , else. have looked everywhere , see nothing mentions it. know way around or missing obvious here?

i build font so.

itextsharp.text.font myfont = new font(itextsharp.text.font.fontfamily.times_roman, 9, itextsharp.text.font.bolditalic, basecolor.black); 

you can see 3rd parameter integer signifying fontstyle font, there no enums available make underlined , bold ,underlined , italic, or three. there has way this. find hard believe itextsharp not account underlined , bold text. ideas?

if @ definition bolditalic you'll see:

public const int bolditalic    = bold | italic; 

this shows how combine these styles using bitwise | (or) operator. of course free redefine these want you'll see them used this:

var myfont = new font(itextsharp.text.font.fontfamily.times_roman, 9, font.bold | font.underline, basecolor.black); 

edit

looking @ source, bold 1 , underline 4 , when | them 5 same value posted. can test every single combination of 5 styles using code below.
