There's nothing to stop you declaring a delegate that accepts a params array, the same as you would define any other method which takes multiple arguments:

delegate void someCustomEvent(params object[] args);

event someCustomEvent sce;

However, it would be unusual. As Kent says, it's more normal to follow the convention on the .Net platform of having event handlers accepting two arguments, the sender (object), and the event arguments (EventArgs, or something deriving from it).
