如何制作一个包含列表的类的列表？

Question

我有一个人为一个人添加一些数据的人。从第二类ListOfP中，我可以在每个添加的新人后显示数据。现在我需要一些帮助，将每个新人都列入清单，并能够显示清单中的每个人及其所有详细信息。任何帮助，将不胜感激。

class Person 
{ 
    public List<string> PhoneNbrList = new List<string>(); 
    public List<string> GetListOfListOfP() { return PhoneNbrList; } 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 

    public void AddNewPerson() 
    { 
     PhoneNbrList = new List<string>(); 
     int i = 1; 
     string str = ""; 
     bool stop = false; 

     do 
     { 
      Console.Write("PhoneNbr [" + i + "]: "); 
      str = Console.ReadLine(); 
      if (str == "n") 
       stop = true; 
      else 
       PhoneNbrList.Add(str); 
      i++; 
     } while (!stop); 
     Console.Write("First name: "); 
     FirstName = Console.ReadLine(); 
     Console.Write("Last name: "); 
     LastName = Console.ReadLine(); 

    } 

    public void ShowPersonData() 
    { 
     for (int i = 0; i < PhoneNbrList.Count; i++) 
      Console.WriteLine("PhoneNbr[" + (i + 1) + "]: " + PhoneNbrList[i]); 

     Console.WriteLine("First name: " + FirstName); 
     Console.WriteLine("Last name: " + LastName); 
    } 
} 


This is the second class 

class ListOfP 
    { 
     static List<Person> ListP = new List<Person>(); 

     static void Main(string[] args) 
     { 
      Person lp = new Person(); 
      int counter = 1; 

      lp.AddNewPerson(); 
      lp.ShowPersonData(); 
      ListP.Add(lp); 


      lp.AddNewPerson(); 
      lp.ShowPersonData(); 
      ListP.Add(lp); 

      Console.ReadLine(); 
     } 
} 

Answer 1

让你的人上课;

class Person 
{ 
    public List<string> PhoneNbrList = new List<string>(); 
    public List<string> GetListOfListOfP() { return PhoneNbrList; } 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 
} 

然后使用泛型为您需要的人名单;

List<Person> myList = new List<Person>; 
Person x = new Person(); 
myList.Add(x); 

，那么你可以通过这个列表循环 - 或做任何你想做的事情

foreach (Person p in myList) 
{ 
//Do something 
} 

Answer 2

至于我也明白了，你需要的是这样的：

UPDATE：

class Person 
{ 
    public Person() 
    { 
     PhoneNbrList = new List<string>(); 
    } 
    public List<string> PhoneNbrList; 
    public List<string> GetListOfListOfP() { return PhoneNbrList; } 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 
} 

List<Person> objPerson = new List<Person>(); 

Person obj1 = new Person(); 
//Initialise obj1 here 
objPerson.Add(obj1); 

Person obj2 = new Person(); 
//Initialise obj2 here 
objPerson.Add(obj2); 

......// Add all the objects to list in same manner 


// Query through list 

foreach(var item in objPerson) 
{ 
    // Access each of the items of list here 
    foreach(var phoneNumbers in item.PhoneNbrList) 
    { 
     **//Access your each phone number here** 
    } 
}
