Which Control To Use For PHP Parsing Editor

I want to develop an application with c#.net(winforms) to be a parser and editor for php. I have many experiences in .net, but I am confused. In fact I need to write an editor in which I can implement syntax coloring, line numbers, gutters, expandable/collapsable regions, ...

I can write it with RichTextBox, but it has many difficulties. Is there an easier way to do it, or is there a component to do this (free and source available of co开发者_JS百科urse), or ... I want to know what various ways of doing this are.

Thanks for your replies

I guess that ScintillaNET will do the trick. (Tho I've never used it my self)
