Acrobat Distiller 5 and Acrobat Distiller 7

Is there any latest way to convert multiple post script  files to pdf using adobe and c#.

Thsnk for reply. 

Am having team license for latest Adobe , but it have Acrobat Distiller 7.0 .

But my client using Acrobat Distiller 5.0 

We have an API for creating PDF from PS files . I can convert single ps file to pdf , but trouble facing when trying to convert batch ps files to pdf

pdfDist.FileToPDF(pathOut & "\Ctc\temp.txt", pathOut & "\Temp\Temp.pdf", "No Downsample")

upb.txt contains belows script which take all ps files in the folder and trying to convert it

/PathName (C:/MyTemp/*.ps) def
/RunDir {
{ /mysave save def
dup = flush
RunFile
clear cleardictstack
mysave restore
}
255 string
filenameforall
} def
PathName RunDir

. Its working fine with Acrobat Distiller 5.0 , but not with Acrobat Distiller 7.0 .
