Alter and update text from C#?

Question

Does anybody know if it's possible to alter and update text from C#?
I've added a reference to Interop.Illustrator.dll COM type library and managed to cobble together have this bit of code
            Illustrator.Application app = new Illustrator.Application();
            Illustrator.Document doc = app.Open(
                "c:\\MyIllustratorDoc.ai",
                Illustrator.AiDocumentColorSpace.aiDocumentRGBColor,
                null);
            foreach(Illustrator.TextFrame textFrame in doc.TextFrames)
                Console.Write(textFrame.Contents);
which just dumps out the contents of all the TextFrames but from the documentation I've found, Contents and everything else that gives access to any text, is read only.
I was hoping to be able to automate the maintenance of various bits of text by picking them up from SQL Server and then amending them directly in the ai file where needed.  Any help would be greatly appreciated.
Cheers,
Tim

Hi,
IPQ-2007-08-20 YES is in 1 field ..
At first is only 'IPQ-2007-08-20' in that field RM06I-LTEX2 now user want to fully utilize this long text field. so want to add something at RHS of this field.
You may refer this link to get clearer idea, what is the user want.

How should I insert 2 column of data (eg 'IPQ-2007-08-20'  and 'YES' ) into this 1 field (RM06I-LTEX2) without overwrite each other?
