Question

我在C＃中编写了一个bubblesort并遇到了这个问题。以下是我的课程，课程结束后我将描述我的问题。

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

namespace BubbleSort
{
class Person
{
    public String FirstName { get; set; }
    public String LastName {get; set;}
    public String PhoneNumber { get; set; }
    public Person(String firstName, String lastName)
    {
        FirstName = firstName;
        LastName = lastName;

    }
}
}



using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Collections;

namespace BubbleSort
{
class ListProvider
{
    //Class Variables
    private StreamReader fileReader;
    //private List<Person> test;

    #region Properties
    public List<Person> TheList
    {
        get { return TheList; }
        set { TheList = value; }
    }
    #endregion

    /// <summary>
    /// I wish C# had a Scanner class :/. How different are these languages really?
    /// </summary>
    /// <param name="fileName"></param>
    public ListProvider(string fileName)
    {
       // test = new List<Person>();            
            using (fileReader = new StreamReader(fileName))
            {
                String line = "";
                while (fileReader.Peek() != -1)
                {
                    line = fileReader.ReadLine();
                    String[] nameArray = line.Split(' ');

                    TheList.Add(new Person(nameArray[0], nameArray[1]));
                    //test.Add(new Person(nameArray[0], nameArray[1]));
                }
            }
        }


}
}


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

namespace BubbleSort
{
class Program
{
    static void Main(string[] args)
    {
        ListProvider listProvider = new ListProvider("C:\\Users\\JC Boss\\Desktop\\Career\\Programming Practice\\BubbleSort\\BubbleSort\\names.txt");
        foreach (Person person in listProvider.TheList)
        {
            Console.WriteLine(person.FirstName + " " + person.LastName);
        }
    }

好。因此，当我尝试向此列表添加一个新Person时，我得到一个堆栈溢出异常。现在，如果我要取消注释List变量测试，并添加到那个。它会工作正常，并不会抛出任何错误。为什么会这样？我环顾四周但却看不出为什么会发生财产？ } }

Answer 1

public List<Person> TheList
{
    get { return TheList; }
    set { TheList = value; }
}

这个setter指的是它自己。任何读取或写入它的尝试都将导致无限递归。

为什么此方法调用导致堆栈溢出的属性？
