Terminology: event raised with parameters?

I am only not sure if one can say that event has parameters. E.g. KeyDown ev开发者_运维百科ent. Should I say that it was raised with two parameters? What is the terminology here?

EDIT:I am trying to find out whether it is correct to say that an event is raised with parameters. Or what is the correct terminology - event with objects holding additional information? Thanks

When you send data with the raised event, its called Arguments.
