我很抱歉发布了很多内容，但我认为你需要看到这一切。
答案 0 :(得分：2)
首先，您需要提供正确的使用声明。
using System;
using System.Collections.Generic;
using System.Linq;
etc.
还有连接错误，在几行上缺少括号等等，会产生编译错误。
Console.WriteLine("Name: " patteAndMelbeToast.getName());
而且，if语句需要一个等于运算符==，而不是=。
您应该能够通过编译器的反馈来解决其他一些问题。
答案 1 :(得分：0)
首发
Console.ReadKey(inputString);
应该是
inputString = Console.ReadLine();
您有一些示例，例如chicken.getNumberServed(1);应为chicken.setNumberServed(1);。
另外，我建议您在Main中包含Console.ReadLine();的最后一行，这样您就可以通过按Enter键来控制控制台窗口关闭的时间。然后你可以实际读出实际输出的内容。
