object sender, EventArgs e

The event handlers for most .net generated events meet the definition of the kind

protected void EventName(object sender, EventArgs e)


sender is a reference to the object that raised the event

On a button click if you check the value of sender.GetType() , you would see something like

e contains the parameters passed by the event

For instance if you are consuming a user created custom event, you could have parameters like
e.pageNumber, e.pageSize etc.
