How to programmatically (C#) update iFile content?

C I have a parameter file containing an array of ApiKeys that I upload to my F5 LTM using an ASP.net web app. I also verify that the file was uploaded with the correct content, no problem!

 

I have created the iFileFile object as well as the iFile object which is referenced in my iRule.

 

I would like to update the content of my setup file programmatically such that my iFileFile object and therefor my iFile object can be updated for use in my iRule.

 

I do NOT want to use the Web GUI or the console interface to do this.

 

What is the C-iControl method call that would enable me to update/modify my iFileFile?

 

This is what I believe is missing at least?

 

Any and all help would be appreciated! Thank you!
