How to get all the full paths from a drawing's?

[Anonymous]

Can somebody tell me how to get some infomation(Font, Outter Reference DWG, LineType File Path ) which a drawing may be dependent on ?

I'm develping a C# program with AutoCAD 2008.  To ensure the drawing to be displayed porperly when it be copied or moved, I Want to get the(font, out reference drawing and line type) full file path, and copy or movie the file to the same distination directory. 

I can't find any API to  (Font, Outter Reference DWG, LineType File Path).

Could someone tell me how to do it?
