Question

我创建了一个名为“Player”的类，它存储每个玩家的数据。该类执行它应该做的事情，但是当在List / Array中存储该类的多个实例时，数组或列表中的所有对象都等于最后存储的对象。

玩家类代码：

public class Player
{
    private static string player_name;
    public Player(string name)
    {
        player_name = name;
    }
    public string Name
    {
        get
        {
            return player_name;
        }
    }
}

用于创建和添加到列表的代码：

//simple string array for names;
string[] example_names = new string[] { "Mike", "Adam", "Jake" };

//creating new object and adding to list<Player>
List<Player> players = new List<Player>();
foreach (string name in example_names)
{
     Player player = new Player(name);
     players.Add(player);
}

//loop for returning the output
string output = "";
foreach (Player player in players)
{
    output += player.Name + ", ";
}
Clipboard.SetText(output);

输出：“Jake，Jake，Jake，”

Answer 1

从班级static中的private static string player_name;移除Player。使用该关键字，您专门告诉它使Player的所有实例具有相同的name。

没有它，name将是实例字段，可以为Player的每个实例单独设置和检索。

数组中的所有对象都等于最后添加的对象c＃
