C# 无法从类内调用方法？

当我尝试运行我的代码时，我收到错误消息“方法'talk'的No重载包含0个参数”，请有人帮助我调用talk方法。抱歉，代码太多了，但我真的不明白我是否出错了

class Program
{
    public void Main(string[] args)
    {
        Critter newcritter = new Critter();

        Console.WriteLine("Enter critter name: ");

        var newname = Convert.ToString(Console.ReadLine());

        newcritter.Name = newname;

        Console.WriteLine("Say Hello to your new critter, {0}!", newcritter.Name);

        var option = Convert.ToString(Console.ReadLine());

        while (option != "0")
        {
            Console.WriteLine(@"
            Critter Caretaker

             0 - Quit
              1 - Listen to your critter
              2 - Feed your critter
              3 - Play with your critter
              ");
            if (option == "0")
            {
                Console.WriteLine("Good-bye.");
            }

            if (option == "1")
            {
                newcritter.talk();
            }

class Critter
    {
        public string Name { get; set; }
        public int Hunger = 0;
        public int Boredom = 0;

        public void PassTime()
        {
            Hunger += 1;
            Boredom += 1;
        }

        public void mood()
        {
            var unhappiness = Hunger + Boredom;
            string m = "";
            if (unhappiness < 5)
            {
                m = "Happy";
            }

            if (unhappiness <= 5 && 
                unhappiness <= 10)
            {
                m = "Okay";
            }

            if (unhappiness <= 11 &&
                unhappiness <= 15)
            {
                m = "Frustrated";
            }

            if (unhappiness <= 16)
            {
                m = "Mad";
            }
        }

        public void talk(string m)
        {
            Console.WriteLine("I'm", Name, "and I feel", m, "now.\n");
            PassTime();
        }

你打电话给newcritter.talk；没有参数，而您的方法需要一个参数public void talkstring m

因此，需要将参数字符串传递给talk方法：

talk方法需要一个字符串参数，因此需要提供一个：

newcritter.talk("fine");

而且，你在这里打电话的方式是错误的。请尝试以下方法：

public void talk(string m)
{
    Console.WriteLine("I'm {0} and I feel {1} now.", Name, m);
    PassTime();
}

错误更清楚地描述了它：

没有具有0个参数的方法对话：

我认为：

if (option == "1")
            {
                newcritter.talk();//error here as there no zero argument talk() method
            }

应该是：

if (option == "1")
            {
               newcritter.talk("somestring");
            }

---

下面是一行代码调用talk：

 if (option == "1")
 {
     newcritter.talk();
 }

以下是您对谈话的定义：

public void talk(string m)

---

我认为错误很明显。

您在这段代码中遗漏了一些东西。您尚未指定需要执行的操作。 正如我所理解的，你在程序课上的时间应该是

    while (option != "0")
    {
        Console.WriteLine(@"
        Critter Caretaker

         0 - Quit
          1 - Listen to your critter
          2 - Feed your critter
          3 - Play with your critter
          ");
        if (option == "0")
        {
            Console.WriteLine("Good-bye.");
        }

        if (option == "1")
        {
            newcritter.talk();
        }
         if (option == "2")
        {
            newcritter.PassTime();
        }
        if (option == "3")
        {
            newcritter.mood();
        }
    }

你的Crtter课程应该是

class Critter
{
    public string Name { get; set; }
    public int Hunger = 0;
    public int Boredom = 0;
    public string m = "Happy";

   // No Change in PassTime() method and  mood() method
   //
    public void talk()
    {
        Console.WriteLine("I'm", Name, "and I feel", m, "now.\n");
        PassTime();
    } 

class Critter
{
    public string Name { get; set; }
    public int Hunger = 0;
    public int Boredom = 0;
    public string m = "Happy";

   // No Change in PassTime() method and  mood() method
   //
    public void talk()
    {
        Console.WriteLine("I'm", Name, "and I feel", m, "now.\n");
        PassTime();
    }
