Question

我正在制作一个带有Button Array的小型tic tac toe游戏，并且我正在创建数组，我想知道是否有一种更优雅的方式来为它们分配数组。我目前的代码是：

MovementPiece[0, 0] = button1;
MovementPiece[0, 1] = button2;
MovementPiece[0, 2] = button3;
MovementPiece[1, 0] = button4;
MovementPiece[1, 1] = button5;
MovementPiece[1, 2] = button6;
MovementPiece[2, 0] = button7;
MovementPiece[2, 1] = button8;
MovementPiece[2, 2] = button9;

我现在的问题是我的程序无法看到按钮，因为它们是在本地声明的。

    public void Form1_Load(object sender, EventArgs e)
    {
        Button[,] MovementPiece = { { button1, button2, button3 }, 
                                  { button4, button5, button6 },
                                  { button7, button8, button9 } };
        //Initiates the button array.

        for (int Row = 0; Row <= 2; Row++)
        {
            for (int Column = 0; Column <= 2; Column++)
            {
                this.Controls.Add(MovementPiece[Row, Column]);
                //Sets the handler for the buttons.
                MovementPiece[Row, Column].Click += new EventHandler(MovementPiece_Click);
            }
        }

 Public void Clear()
 {
 //Can not see buttons.
 }

谢谢，我是一个开始，所以放轻松：|

当然你可以使用这样的数组初始化器：

Button[,] MovementPiece = { { button1, button2, button3 }, 
                              { button4, button5, button6 },
                              { button7, button8, button9 }
                            };

不要使用这样的数组，而是将所有按钮移动到面板中。（它是一个控件）你可以循环访问面板＆＃34; Controls＆＃34;列表。

foreach(Button button IN mypanel.Controls){
    //do stuff
}

更容易使用。

正如我在评论中所述，您需要在类级别声明您的数组，并在Form_Load事件处理程序中初始化它，这样整个表单都可以看到它。这样的事情应该有效。

public partial class Form1 : Form
{
    Button[,] MovementPiece;  //Declare at the class level
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        MovementPiece = new Button[,]{ { button1, button2, button3 }, 
                          { button4, button5, button6 },
                          { button7, button8, button9 }
                        }; //Initialized in your Form Load event

        // Do your button initialization here
    }
}

更优雅的方式添加按钮到数组
