It really depends on whether the device you're connecting to can understand serial data or not.
It would probably help better if you told us exactly what you're trying to do, then we could suggest the best method.
I.e. What device are you trying to connect to?
How is it possible to electronically control that device?
I'm trying to connect a device called Arduino (http://www.ladyada.net/learn/arduino/index.html)
there is a tutorial in how to control it using c++, but im looking for a way to use it using c#.
thanks

I can't get to the site you linked here at work, but my guess is that if the device has existing C++ in the form of source code or (dare'st I say it) DLLs, you can import the code into your project and make the function calls from C#. (See: DLLImport).
That is what I do with a number of interfaces I use at my job, because most of the interfaces were written in C++, not C#.
