为什么我不能设置数组值？它为什么不拉绳子呢？

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"; }

我一直有个错误说不能把字符串转换成播放器类型..。

下面是player类，它还设置名称的属性.

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对象的数组：

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

你想在数组中放一个字符串。

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

这不起作用，只能在数组中放置一个Player实例。

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隐式铸造。你需要这样的东西：

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

当然，您将需要一个带有字符串参数的Player构造函数。

编辑:显式改为隐式。隐式运算符将导致代码编译。
