如何解决“方法'的重载不接受0个参数”？ [英] How to fix "No overload for method ' ' takes 0 arguments"?

问题描述

如何解决此错误？

方法'output'的重载不接受0个参数。

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

错误在 fresh.output（）;的最底部。

The error is at the very bottom at "fresh.output();".

我不知道我在做什么错误。有人可以告诉我该怎么做才能修复代码吗？

I don't know what I'm doing wrong. Can someone tell me what I should do to fix the code?

这是我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication_program
{
    public class Numbers
    {
        public double one, two, three, four;
        public virtual void output(double o, double tw, double th, double f)
        {
            one = o;
            two = tw;
            three = th;
            four = f;
        }
    }
    public class IntegerOne : Numbers
    {
        public override void output(double o, double tw, double th, double f)
        {
            Console.WriteLine("First number is {0}, second number is {1}, and third number is {2}", one, two, three);
        }
    }
    public class IntegerTwo : Numbers
    {
        public override void output(double o, double tw, double th, double f)
        {
            Console.WriteLine("Fourth number is {0}", four);
        }
    }
    class program
    {
        static void Main(string[] args)
        {
            Numbers[] chosen = new Numbers[2];

            chosen[0] = new IntegerOne();
            chosen[1] = new IntegerTwo();

            foreach (Numbers fresh in chosen)
            {
                fresh.output();
            }     
            Console.ReadLine();
        }
    }
}

推荐答案

它告诉您方法输出需要参数。这是输出的签名：

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)

因此，如果您想跟注，则需要四次加倍。

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

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

或者以硬编码值为例：

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