数组中的所有对象都等于最后添加的对象c#

Question

我创建了一个名为"Player"的类,它存储每个玩家的数据.该类执行它应该执行的操作,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:"杰克,杰克,杰克,"

删除static从private static string player_name;在课堂上Player.使用该关键字,您明确告诉它使所有实例都Player具有相同的关键字name.

没有它,name将是一个实例字段,并且可以为每个实例单独设置和检索Player.
