我正在制作一个定制的Tic Tac Toe游戏，表格中有三个Tic Tac Toe框架。
而不是创建三倍于3x3方形的按钮，我认为最好制作一个自定义控件，其中包含我想要的阵型中的九个按钮，因此我可以在表单中放置三次并访问该阵型中的每一个按钮。
我对继承和自定义控件很陌生，所以我希望得到您的示例或说明帮助。

在这种情况下，您可以使用UserControl。这比创建自定义控件更容易，自定义控件需要从现有控件派生控件并对其进行增强。在VS中右键单击您的项目并选择“添加”＆gt; “新物品...”。在Windows窗体部分中，选择“用户控件”。将其命名为“TicTacToeUserControl”。您可以像设计表单一样设计用户控件。然后，它将自动显示在当前项目的工具箱中，并准备好放在表单上。
<强>更新
这里有更多解释。在TableLayoutPanel上放置UserControl。将Dock更改为Fill。添加行和列以使两者中的三个都更改并将其大小模式更改为Percent并将这些值更改为33.33。从左到右，然后从上到下为每个表字段添加一个按钮，以便按阅读顺序将按钮命名为“button1”，“button2”等。保存用户控件（我的VS在这一点上有一个小故障，我不得不重新开始）。
创建我们将用作按钮点击事件的事件参数的类
public class ButtonClickedEventArgs : EventArgs
{
public ButtonClickedEventArgs(TicTacToeUserControl userControl, Button button,
int buttonNumber, int row, int column)
{
UserControl = userControl;
Button = button;
ButtonNumber = buttonNumber;
Row = row;
Column = column;
}
public TicTacToeUserControl UserControl { get; private set; }
public Button Button { get; private set; }
public int ButtonNumber { get; private set; }
public int Row { get; private set; }
public int Column { get; private set; }
}
更改用户控件的代码，使其看起来像这样
[DefaultEvent("ButtonClicked")]
public partial class TicTacToeUserControl : UserControl
{
public event EventHandler<ButtonClickedEventArgs> ButtonClicked;
public TicTacToeUserControl()
{
InitializeComponent();
}
private void button_Click(object sender, EventArgs e)
{
OnButtonClicked((Button)sender);
}
private void OnButtonClicked(Button button)
{
var eh = ButtonClicked;
if (eh != null) {
int buttonNumber =
Int32.Parse(button.Name.Substring(button.Name.Length - 1));
int row = (buttonNumber - 1) / 3;
int col = (buttonNumber - 1) % 3;
eh(this,
new ButtonClickedEventArgs(this, button, buttonNumber, row, col));
}
}
}
为属性窗口中所有按钮的click事件选择事件处理程序“button_Click”切换到Event（闪存符号）。不要为每个按钮创建一个新的按钮。点击F6（编译）
您的控件已准备就绪，可以从工具窗口拖放到表单上。根据需要调整大小。双击它。由于我们为表单指定了DefaultEventAttribute，VS将自动创建此事件处理程序
private void ticTacToeUserControl1_ButtonClicked(object sender,
ButtonClickedEventArgs e)
{
}
将此代码行添加到其中以测试用户控件
MessageBox.Show(e.UserControl.Name + " " + e.Button.Name + " " +
e.ButtonNumber + " " + e.Row + " " + e.Column);
注意：这实际上并没有创建新控件，只是创建了一个模板

最好的方法是使用用户控件，但不是通过设计器创建按钮，而是通过代码创建按钮，这将帮助您检测单击的按钮;
public partial class UserControl1 : UserControl
{
private List<Button> buttons = new List<Button>(9);
public UserControl1()
{
InitializeComponent();
}
private void UserControl1_Load(object sender, EventArgs e)
{
int line = 0;
int lastleft = 0;
int lasttop = 0;
for (int i = 1; i < 10; i++)
{
Button btn = new Button();
btn.Text = string.Empty;
btn.Parent = this;
btn.Top = lasttop;
btn.Left = lastleft;
btn.Width = 30;
btn.Height = 30;
btn.Name = i.ToString(CultureInfo.InvariantCulture);
if (i % 3 == 0)
{
lastleft = 0;
lasttop += 35; // 30 for height and 5 for spacing
}
else
{
lastleft += 35; // 30 for width and 5 for spacing
}
btn.Click += BtnOnClick;
buttons.Add(btn);
}
}
private void BtnOnClick(object sender, EventArgs eventArgs)
{
//ur logic to check game status
// how to know button?
Button btn = sender as Button;
if (btn != null)
{
MessageBox.Show(String.Format("You clicked : {0}", btn.Name), Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
}

这不是一个答案，但它的评论太长了（所以请不要拒绝投票而不是答案）
在这种情况下，我不会使用自定义控件，而只是使用控件数组。
例如，只需在网格形式中制作9个控件，然后将它们分配给数组
Button[][] buttons = new Button[ROW_COUNT][];
for (int i = 0; i < ROW_COUNT; i++)
{
buttons[i] = new Buttons[COLUMN_COUNT];
}
buttons[0][0] = btnTopLeft;
...
