覆蓋ToString但打印數組時顯示類型

Question

雖然我正在打印值，但我沒有獲取值，而是打印類型。 在PlayerBO類Console.WriteLine(playerList);打印player[] 但我需要打印值。

我的代碼有什麼問題？

public class Program 
{ 
    public static void Main(string[] args) 
    { 
     Player[] p= new Player[100]; 
     Console.WriteLine("Enter the number of players"); 
     int n = int.Parse(Console.ReadLine()); 
     int i; 
     for (i = 0; i < n; i++) 
     { 
      p[i] = new Player(); 
      Console.WriteLine("Enter the player name"); 
      p[i].Name = Console.ReadLine(); 
      Console.WriteLine("Enter the country name"); 
      p[i].Country = Console.ReadLine(); 
      Console.WriteLine("Enter the skill"); 
      p[i].Skill = Console.ReadLine(); 
     } 
     PlayerBO pb=new PlayerBO(); 
     pb.DisplayPlayerDetails(p); 
    } 
} 

public class Player 
{ 
    private string _country; 
    private string _skill; 
    private string _name; 
    public Player(string _name, string _country, string _skill) 
    { 
     this._name = _name; 
     this._country = _country; 
     this._skill = _skill; 
    } 
    public Player() { } 
    public string Name 
    { 
     get { return this._name; } 
     set { this._name = value; } 
    } 

    public string Country 
    { 
     get { return this._country; } 
     set { this._country = value; } 
    } 

    public string Skill 
    { 
     get { return this._skill; } 
     set { this._skill = value; } 
    } 
    public override string ToString() 
    { 
     return string.Format("{0,-20}{1,-20}{2,0}", Name, Country, Skill); 
    } 
} 

public class PlayerBO 
{ 
    public void DisplayPlayerDetails(Player[] playerList) 
    { 
     playerList = new Player[100]; 
     Console.WriteLine("Player Details"); 
     Console.WriteLine(playerList); 
    } 
} 

Answer 1

Console.WriteLine(playerList)將執行用於陣列中實現的ToString - 這是不一樣的覆蓋該數組中的對象類型的ToString。

要打印的數值數組中，你需要遍歷它：

foreach(var item in playerList) 
{ 
    Console.WriteLine(item); 
} 

或者另一種方式是使用string.Join：

Console.WriteLine(string.Join(Environment.NewLine, playerList)); 

而且，看看自動屬性：

//Instead of this: 
public string Name 
{ 
    get { return this._name; } 
    set { this._name = value; } 
} 

//You can do this: 
public string Name { get; set; }
