These data can be accessed through the internet thanks to a SOAP based web service that we have set up. We have also developed a web service client using Dot.NET framework, which is built into a .dll file.

If you can call them from C, you can write a simple wrapper.  See 
Writing R Extensions for how to write the R to C interface.  Writing the 
interface from to your DLL is up to you.  (It's possible R could call 
your DLL directly, but it is somewhat limited in the kinds of interfaces 
it supports, so you usually need the wrapper.)
