为什么我不能设置数组值？为什么它不投弦？

Question

Private Player[] players = new Player[2];
    private int currentPlayerIndex = 0;



    public Game(Form1 form)
    {

        for (int i = 0; i < players.Length; i++) {
            players[i] = (string)"Player"; }

我一直收到错误消息，说它无法将字符串转换为播放器类型...

下面是播放器 class，它还设置了属性名称...

class Player
{
    private string name = "";



    public  Player(string name)
    {
        name = "Player";

    }


    public string Name {
        get { return name; }

        set { name = value; }

    }

Answer 1

players 是 Player 个对象的数组：

private Player[] players = new Player[2];

您正在尝试将字符串放入数组中。

players[i] = (string)"Player";

那不行，你只能把Player的一个实例放到数组

players[i] = new Player("Player1");

Answer 2

因为您的代码没有提供从字符串到播放器的 implicit cast。你需要这样的东西：

public static implicit operator Player(string str)
{
    return new Player(str);
}

当然，您将需要一个接受字符串参数的 Player 构造函数。

编辑：将显式更改为隐式。隐式运算符将导致代码编译。

为什么我不能设置数组值？为什么它不投弦？

Why can't I set the array value? why won't it cast the string?

c#

arrays

class

casting

non-static
