我的阵列在制作垄断游戏时出现问题

Question

我正试图创建一个数组来存储垄断板上可用的所有位置，但在创建数组时，我得到了

"无法隐式转换类型"(string，string，string、string、string("以串"；

。

private void pictureBox1_Click_1(object sender, EventArgs e)
{
string[,,,,]BoardPos;
BoardPos = new string[39, 0, 4, 0, 0];
BoardPos[0, 0, 0, 0, 0] = ("Go", "+200", "CurrentPlayer", "", "");
BoardPos[1, 0, 0, 0, 0] = ("Old Kent Road", "-60", "CurrentPlayer", "", "");
}

Answer 1

此语法：

("Go", "+200", "CurrentPlayer", "", "");

实际上是创建一个字符串元组，而不是字符串数组。

修复方法是重写代码以利用C#的面向对象特性。我建议您通过创建一个类来保存相关字段来简化代码：

public interface IMonopolySquare
{
public string Name { get; }
public void PlayerLandsOnEvent(Player player);
public void PlayerPassesSquareEvent(Player player);
public void SetOwner(Player player);
}
public class GoSquare : IMonopolySquare
{
public string Name { get => "Go" }
public void PlayerLandsOnEvent(Player player)
{
// Do nothing - player has to pass to receive £200.
}
public void PlayerPassesSquareEvent(Player player)
{
player.AddMoney(200);
}
public void SetOwner(Player player)
{
throw new Exception ("You can't buy go!!");
}
}
public class PropertySquare : IMonopolySquare
{
private Player _owner = null;
private int _rentWithoutHouse;
private Color _color;
public PropertySquare(
string name,
int rentWithoutHouse,
Color color)
{
Name = name;
_rentWithoutHouse = rentWithoutHouse;
_color = color;
}
public string Name {get;}
public void PlayerLandsOnEvent(Player player)
{
if (_owner != null && _owner != player)
{
player.SubtractMoney(_rentWithoutHouse); 
}
}
public void PlayerPassesSquareEvent(Player player)
{
// Do nothing.
}
public void SetOwner(Player player)
{
if (owner != null)
{
throw new Exception("Can't buy something that's already been bought!");
}
else
{
_owner = player;
}
}
}
// the Player class is left as an exercise for the reader...

然后你的"董事会"变得简单多了：

var board = new IMonopolySquare[] {
new GoSquare(),
new PropertySquare("Old Kent Road", "2", Color.Brown),
// etc.
}
