The situation
When assigning a Click
event to a button, I get a premade eventhandler which specifies an object sender
and RoutedEventArgs args
.
Now for my implementation of this eventhandler I don't use sender
and args
, and therefore I get a message saying that I should remove the parameters.
I am aware of the discard (_
) operator in C#, however using this allows me to only discard one of the parameters (if I use _
again for args
I get an error saying that I already have a parameter called _
).
I have searched over the internet but there are only examples of discarding out
variables, using discard in lambda expressions, etc. but nothing about this.
For example I want to convert something like this:
private void Button_Click(object sender, RoutedEventArgs args)
{
DoSomethingThatDoesNotUseSenderAndArgs();
}
to this:
private void Button_CLick(object _, RoutedEventArgs _)
{
DoSomethingThatDoesNotUseSenderAndArgs();
}
My question
Should I just ignore this message? Or suppress it since there does not seem to be a way of solving it without using the parameters in the implementation? Or is there actually a way of discarding both parameters and thus remove this annoying message?
