堆栈溢出异常 - 为什么？

Question

我不断得到一个堆栈溢出异常.我已经把它缩小到这个类来试图弄清楚出了什么问题,但我根本不知道为什么我一直收到这个错误信息？最初我在另一个类中有用户界面,但只是为了消除其他一切,比如我的调用方法中的问题,我将基本要素移到这个类中,试图弄清楚出了什么问题.我以为这可能是我的财产？也许对其他人来说很明显,但我根本不明白.

由于我对编程很陌生,所以我会很感激我对错误的帮助.根据我的理解,当你有无限循环之类的东西时会出现这个问题？

namespace MyNameSpace
{
    public class Customers
    {
        private List<Customers> customers; 

        public Customers()
        {
            customers = new List<Customers>();

            AddCustomer(new Customers() 
            { 
            Name = "A", Telephone="1" 
            });
        }

        public string Name
        {
            get;
            set;
        }
        public string Telephone
        {
            get;
            set;
        }

        public void RunTest()
        {

            Console.WriteLine();
            Console.WriteLine("****** VIDEOSTORE ******");
            Console.WriteLine();
            Console.WriteLine("1. Show Customers");
            Console.WriteLine("6. Quit");

            string userChoice = Console.ReadLine();

            switch (userChoice)
            {
                case "1": 
                    View();
                    break;         

                    break;
                case "2":
                    break;
            }
        }

        public void View()
        {
            foreach (Customers c in customers)
            {
                Console.WriteLine();
                Console.WriteLine(c.Name);
                Console.WriteLine(c.Telephone);
                Console.WriteLine();
            }
        }

        public void AddCustomer(Customers custom)                           
        {
            customers.Add(custom);          
        }
    }
}

Answer 1

在Customers构造函数中,再次调用Customers构造函数,创建无限递归.

您应该为客户列表和单个客户提供单独的类:

namespace MyNameSpace
{
    public class Customer
    {
        public string Name
        {
            get;
            set;
        }
        public string Telephone
        {
            get;
            set;
        }
    }

    public class Customers
    {
        private List<Customer> customers; 

        public Customers()
        {
            customers = new List<Customer>();

            AddCustomer(new Customer() 
            { 
            Name = "A", Telephone="1" 
            });
        }


        public void RunTest()
        {

            Console.WriteLine();
            Console.WriteLine("****** VIDEOSTORE ******");
            Console.WriteLine();
            Console.WriteLine("1. Show Customers");
            Console.WriteLine("6. Quit");

            string userChoice = Console.ReadLine();

            switch (userChoice)
            {
                case "1": 
                    View();
                    break;         

                    break;
                case "2":
                    break;
            }
        }

        public void View()
        {
            foreach (Customer c in customers)
            {
                Console.WriteLine();
                Console.WriteLine(c.Name);
                Console.WriteLine(c.Telephone);
                Console.WriteLine();
            }
        }

        public void AddCustomer(Customer customer)                           
        {
            customers.Add(customer);          
        }
    }
}

您正在调用在 Customers 构造函数中创建新的 Customers 对象。
