How to fix “No overload for method ' ' takes 0 arguments”?

Question

How can I fix this error?

\"No overload for method \'output\' takes 0 arguments\".

The error is at the very bottom at \"fresh.o

Answer 1

It's telling you that the method "output" needs arguments. Here's the signature for "output":

public override void output(double o, double tw, double th, double f)

So if you want to call that you need to pass in four doubles.

fresh.output(thing1,thing2,thing3,thing4);

Or to use hard coded values as an example:

fresh.output(1,2,3,4);

Answer 2

You're calling the output method with 0 (zero) parameters, but you have declared it to receive 4 double values. The compiler doesn't know what it should call, since there is no output method with no parameter.

Answer 3

fresh.output() expect 2 parameters and you're not providing them

Answer 4

There's no method named output that takes 0 arguments, there's only one that accepts 4 arguments. You must pass parameters to output():

foreach (Numbers fresh in chosen)
{
    fresh.output(o, tw, th, f);
}

Answer 5

All your implementations of method output takes arguments. Supply the arguments and you should be able to compile.

Like this:

fresh.output(1, 2, 3, 4);
