Question

你能告诉我，请问如何在组合框中设置水平中心动态按钮？有没有像这样的textBox1.TextAlign = HorizontalAlignment.Center？

private void Form1_Load(object sender, EventArgs e)
    {
        Button[,] Buttons;  

        Buttons = new Button[4, 4];
        int c,r;

        for (r = 0; r < 4; r++) for (c = 0; c < 4; c++)
        {
            Buttons[r, c] = new Button();
            Buttons[r, c].Parent = groupBox1;
            Buttons[r, c].Top = 50 + r * 25;
            Buttons[r, c].Left = 30 + c * 40;
            Buttons[r, c].Width = 40;                     
        }

    }

Answer 1

您需要计算组框左边框的偏移量如果有4个尺寸为40的按钮，则按钮会占用160像素的空间如果组框的宽度为400像素，则

 int leftOffset = (groupbox1.Width - (40 * numberOfButtons)) / 2; // (400 - 160) / 2

现在使用此偏移量

   Buttons[r, c].Left = leftOffset + c * 40;

Answer 2

这应涵盖x轴和y轴居中：

Button[,] buttons = new Button[4, 4];
        int c, r;

        int xOffset = (groupBox1.Width - (40 * 4)) / 2;
        int yOffset = (groupBox1.Height - 25 * 4) / 2;

        for (r = 0; r < 4; r++) for (c = 0; c < 4; c++)
            {
                buttons[r, c] = new Button {Parent = groupBox1, Top = yOffset + r*25, Left = xOffset + c*40, Width = 40};
            }
        buttons[0, 0].Text = "1";

尝试使用Fow Layout Panel添加按钮，例如简单的面板。
