Pass Arguments from c# to get in DXL script

I'm New DXL.

I would like to know how to "pass arguments to a DXL" from a c# file 

Scenario: I want to pass Arg1 and Arg2 from c#  to the DXL script and to access it within DXL.

But I dono how to set the arguments in c# and to get in DXL file. I have been searching for this on " www.ibm.com/developerworks/community/forums" but no luck.

C# code:

doors.runFile(" Arg 1 Arg2 C:\\Desktop\\retreive.dxl");

Team your response will be really helpful.

P.S I'm working on Doors 9.x

Thanks in advance

Best Regard,

Nabil
