How to programmatically control VLC search in milliseconds?

I am writing a C # application that manages two VLC instances through the VLC remote management interface. I need to control the position in the stream of each instance as much as possible. The RC search command gives only control in seconds, so any part of a second is not possible.

Does anyone have a recommendation that will allow me to control the search for milliseconds in C #? I looked at C # shells, but none of them are supported for the current version of VLC. I would like to continue to use the RC interface for simplicity, if possible.
