Question

为澄清起见，我使用Microsoft Visual Studio并试图将cmd格式转换为可爱的小交互式终端。我是一个基础知识的初学者，并且我知道这对我一个熟练的人来说可能是一个雄心勃勃的项目。目前，我唯一感到困惑的是如何告诉程序我希望它在else if语句的约束下重新开始。

static void Main(string[] args)
        {
            Console.WriteLine("What's your name?");
            string name = Console.ReadLine();
            Console.WriteLine("Hello, " + name);
            Console.WriteLine("What's your age?");
            string age = Console.ReadLine();
            Console.WriteLine("Your name is " + name + " and you are " + age + " years old, Correct?");
            string val = Console.ReadLine();
            if (val == "yes")
            {
                Console.WriteLine("Data confirmed, thank you for your cooperation!");
            }
            else if (val == "no")
            {       //I would like to restart the code if this condition is met
                Console.WriteLine("Incorrect data provided, please try again");
            }
            else
            {       //The issue with this line is that I want it to just ask if the data is correct again
                Console.WriteLine("That is not a valid response, try answering with a yes or no");
            }

尝试类似这样的方法。基本上，您是将代码包装在一个循环中（在这种情况下，是一个“ do ... while”循环，并添加一个标志，指示程序是否应该“重新开始”。

static void Main(string[] args)
{
    bool finished;

    do
    {
        finished = true;
        Console.WriteLine("What's your name?");
        string name = Console.ReadLine();
        Console.WriteLine("Hello, " + name);
        Console.WriteLine("What's your age?");
        string age = Console.ReadLine();
        Console.WriteLine("Your name is " + name + " and you are " + age + " years old, Correct?");
        string val = Console.ReadLine();
        while(val != "yes" && val != "no") {
            Console.WriteLine("That is not a valid response, try answering with a yes or no");
            val = Console.ReadLine();
        }
        if (val == "yes") {
            Console.WriteLine("Data confirmed, thank you for your cooperation!");
        }
        else if (val == "no") {
            Console.WriteLine("Incorrect data provided, please try again");
            finished = false;
        }
    } while(!finished);
}

您可以将代码分解为单独的方法，然后从Main（）方法中调用它。然后，在您的else语句中，您可以让新方法本身进行调用，以便再次执行。（免责声明：自编写C＃以来已经有很长时间了。）

static void Main(string[] args) {
  askName();
}

static void askName() {
  Console.WriteLine("What's your name?");
  string name = Console.ReadLine();
  Console.WriteLine("Hello, " + name);
  Console.WriteLine("What's your age?");
  string age = Console.ReadLine();
  Console.WriteLine("Your name is " + name + " and you are " + age + " years old, Correct?");
  string val = Console.ReadLine();

  if (val == "yes") {
    Console.WriteLine("Data confirmed, thank you for your cooperation!");
  } else  if (val == "no") {
    askName();
  } else {
    //The issue with this line is that I want it to just ask if the data is correct again
    Console.WriteLine("That is not a valid response, try answering with a yes or no");
  }
}

如果满足特定条件，我将如何编程我的代码以重新开始？
