How to call a method passing arguments so that vs doesn't swear?

Question

WPF

the text should just change to something else when the user hits enter and the keydown method is called again,
what vs says when hovering over KeyEventArgs: "KeyEventArgs is a type that is invalid in this context"

Answer 1

what is it anyway?
looks like you are trying to declare a KeyDown method. out, even the types of the parameters were specified

Answer 2

You need to remove the argument types from the call. It will look like this: KeyDown(sender, e);
