C＃groupBox乐透，需要帮助为组框分配变量

Question

        private void LineUpNumbers ()
        {
        Array.Sort(lineArray[currentSelectedLine]);    // Sorts the array in ascending order.
        string numberBox = "Line" + (currentSelectedLine + 1).ToString() + "NumberBox";
        string nb;

        Image[] CircleColours = new Image[6] {Properties.Resources.BlueCircle, Properties.Resources.RedCircle , Properties.Resources.OrangeCircle , Properties.Resources.PurpleCircle , Properties.Resources.GreenCircle , Properties.Resources.YellowCircle};
        Random r = new Random();
        CircleColours = CircleColours.OrderBy(x => r.Next()).ToArray();


        for (int i = 0; i <6; i++)    // Populates NumberBoxes with the numbers from the array
        {
            nb = numberBox + (i + 1);
            Line1.Controls[nb].Text = lineArray[currentSelectedLine][i].ToString();
            Line1.Controls[nb].BackgroundImage = CircleColours[i];
        }

    }

嗨，在上面的代码片段中，我想将Line1更改为字符串变量，但是我不确定这样做的正确语法。 有人可以提供解决方案吗？ 这是C＃

Line1是GrouBox名称。 我希望能够将Line1更改为字符串。 像这样：

string groupBoxName = "Line1";
groupBoxName.buttonName.BackgroundImage = CircleColours[i];

该代码虽然不起作用

Answer 1

您可以使用Form this.Controls数组的Controls数组...

string groupBoxName = "Line1";
Control groupBox = this.Controls[groupBoxName];
groupBox.Controls[nb].BackgroundImage = CircleColours[i];

...就像从GroupBox的Controls数组动态获取NumberBox的方式一样。
