我最近做了一个C# WinForm计算器项目，它填充了一个3x4的文本框块。像这样：
3x4 block of text boxes in the form pluss the input TextBoxes
这是代码：

private void calculate_Click(object sender, EventArgs e)
{
    TextBox[][] textBoxOutputGroups = new[]
    {
        new [] { tb_Stress111, tb_Stress112, tb_Stress113, },
        new [] { tb_Stress121, tb_Stress122, tb_Stress123, },
        new [] { tb_Stress131, tb_Stress132, tb_Stress133, },
        new [] { tb_Stress141, tb_Stress142, tb_Stress143, },
    };

    if (TextBox1.Text == "" || TextBox2.Text == "")
    {
        MessageBox.Show("Some textboxes are empty!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
    else
    {
        double var1;
        double var2;
        double var3;

        var1 = Convert.ToDouble(TextBox1.Text, CultureInfo.InvariantCulture);
        var2 = Convert.ToDouble(TextBox2.Text, CultureInfo.InvariantCulture);

        if (TextBox3.Text == "")
        {
            var3 = (-0.007 * var1 * 2) + 1.8;
        }

        else
        {
            var3 = Convert.ToDouble(TextBox3.Text, CultureInfo.InvariantCulture);
        }

        for (int WP = 0; WP <= 3; WP++)
        {
            var S1 = Math.Pow((var2 - var1) * WP, 2);
            var S2 = Math.Pow(4 + var3, 2);
            var S3 = Math.Pow(var1, 2);

            double[] outputValues = new[]
            {
                S1 * var2 / 3,
                S1 * S3 / WP,
                var3 + var1 * S2 / WP,
            };

            for (int i = 0; i < outputValues.Length; i++)
            {
                 textBoxOutputGroups[WP][i].Text =
                     outputValues[i].ToString(CultureInfo.CreateSpecificCulture("en-GB"));
            }

         }

    }
}

这一个应该填补了一组12个文本框。
我现在要做的是添加额外的5组3x4文本框组，其输出将根据包含'j'变量的新循环的条件进行填充和修改，还将添加新的tadd变量。
大概是这样的：

TextBox[][] textBoxOutputGroups = new[]
{
    new [] { tb_Stress111, tb_Stress112, tb_Stress113, },
    new [] { tb_Stress121, tb_Stress122, tb_Stress123, },
    new [] { tb_Stress131, tb_Stress132, tb_Stress133, },
    new [] { tb_Stress141, tb_Stress142, tb_Stress143, },
    new [] { tb_Stress211, tb_Stress212, tb_Stress213, },
    new [] { tb_Stress221, tb_Stress222, tb_Stress223, },
    new [] { tb_Stress231, tb_Stress232, tb_Stress233, },
    new [] { tb_Stress241, tb_Stress242, tb_Stress243, },
    new [] { tb_Stress311, tb_Stress312, tb_Stress313, },
    new [] { tb_Stress321, tb_Stress322, tb_Stress323, },
    new [] { tb_Stress331, tb_Stress332, tb_Stress333, },
    new [] { tb_Stress341, tb_Stress342, tb_Stress343, },
    new [] { tb_Stress411, tb_Stress412, tb_Stress413, },
    new [] { tb_Stress421, tb_Stress422, tb_Stress423, },
    new [] { tb_Stress431, tb_Stress432, tb_Stress433, },
    new [] { tb_Stress441, tb_Stress442, tb_Stress443, },
    new [] { tb_Stress511, tb_Stress512, tb_Stress513, },
    new [] { tb_Stress521, tb_Stress522, tb_Stress523, },
    new [] { tb_Stress531, tb_Stress532, tb_Stress533, },
    new [] { tb_Stress541, tb_Stress542, tb_Stress543, },
    new [] { tb_Stress611, tb_Stress612, tb_Stress613, },
    new [] { tb_Stress621, tb_Stress622, tb_Stress623, },

上面的这个只填充了原始textBoxOutputGroups中的文本框，其余的为空。
除非有更好的选择，否则除了添加额外的textBoxOutputGroups或将所有新的文本框添加到现有的组中之外，我看不到其他方法。
我该怎么做？

试试这个方法。
创建一个自定义的UserControl（我将其命名为TextBoxesBlock）。该UserControl应该代表一组3x4的TextBox：

的数据
对于每个TextBox，设置一个Tag属性，其中包含TextBox的编号（从1到12），例如：

的
标记将用于正确地计算和排序控件，以在代码隐藏中构建TextBox的二维3x4数组。该支持数组将用于计算（确切地说，通过“行”（Stress）和“列”（Wall Place）的索引轻松访问具体的TextBox）。
此外，在UserControl的代码隐藏中提供了计算方法。从您的示例中假设，计算一半取决于某些用户输入值，一半取决于以前的TextBoxesBlock，所以我决定使用该参数作为方法参数：

TextBoxesBlock.cs：

public partial class TextBoxesBlock : UserControl
{
    private readonly TextBox[,] _textBoxGroup = new TextBox[3, 4];
    private readonly CultureInfo _enGBCulture = CultureInfo.CreateSpecificCulture("en-GB");

    public TextBoxesBlock()
    {
        InitializeComponent();

        // Get a list of TextBoxes, ordered by Tag property (Tag should contain TextBox "number")
        var textBoxes = this.Controls.OfType<TextBox>().OrderBy(tb => int.Parse(tb.Tag?.ToString())).ToList();
        var textBoxIndex = 0;
        // Fill backing array of TextBoxes with rerefences to TextBoxes on Form
        for (var wallPlace = 0; wallPlace < 4; wallPlace++)
            for (var stress = 0; stress < 3; stress++)
            {
                _textBoxGroup[stress, wallPlace] = textBoxes[textBoxIndex];
                textBoxIndex++;
            }
    }

    public void Calculate(int j, double var1, double var2, double var3)
    {
        if (j > 1)
        {
            var tadd = ((1.25 * var3) - var3) / 6;
            var3 += ((Math.Abs(7 - j) * -1) + 6) * tadd;
        }

        for (int wallPlace = 0; wallPlace < 4; wallPlace++)
        {
            var stressX1 = Math.Pow((var2 - var1) * wallPlace, 2);
            var stressX2 = Math.Pow(4 + var3, 2);
            var stressX3 = Math.Pow(var1, 2);

            var stressValues = new[]
            {
                stressX1 * var2 / 3,
                stressX1 * stressX3 / wallPlace,
                var3 + var1 * stressX2 / wallPlace
            };

            for (int stress = 0; stress < stressValues.Length; stress++)
                _textBoxGroup[stress, wallPlace].Text = stressValues[stress].ToString(_enGBCulture);
        }
    }
}

字符串
在另一个表单中，我添加了FlowLayoutPanel（下面的flp1），它将包含TextBoxesBlock s，并添加了其中的6个：

public MainForm
{
    InitializeComponent();
    // ...
    for (var i = 0; i < 6; i++)
        flp1.Controls.Add(new TextBoxesBlock());

    // ...
}

型
最后，在按钮处理程序中，您只需从FlowLayoutPanel接收TextBoxesBlock的列表，并在每个列表上迭代调用Calculate方法并提供必要的参数（arguments）。由于您没有为var1，var2和var3提供初始值，因此我只为所有TextBoxesBlock添加1：

private void calculate_Click(object sender, EventArgs e)
{
    //if (TextBox1.Text == "" || TextBox2.Text == "")
    //{
    //    MessageBox.Show("Some textboxes are empty!", ...);
    //    return;
    //}

    double var1;
    double var2;
    double var3;

    //var1 = Convert.ToDouble(TextBox1.Text, CultureInfo.InvariantCulture);
    //var2 = Convert.ToDouble(TextBox2.Text, CultureInfo.InvariantCulture);
    //if (TextBox3.Text == "")
    //    var3 = (-0.007 * var1 * 2) + 1.8;
    //else
    //    var3 = Convert.ToDouble(TextBox3.Text, CultureInfo.InvariantCulture);

    var blocks = flp1.Controls.OfType<TextBoxesBlock>().ToList();

    for (var j = 0; j < blocks.Count; j++)
    {
        var textBoxesBlock = blocks[j];
        textBoxesBlock.Calculate(j + 1, 1, 1, 1);
    }
}

型
结果我得到：

的
也许不是一个“现成的复制”解决方案，但我希望你会得到的想法。

我同意让一个UserControl来表示每个3x4块更有意义，但是你已经表明你想保持当前的设置。
考虑到这一点，您可以通过使用Controls.Find()和递归搜索选项“按名称”搜索每个TextBox。
它可以归结为：

String group = "4";
String wall = "3";
String stress = "1";
String ctlName = "tb_Stress" + group + wall + stress;
Control[] ctls = this.Controls.Find(ctlName, true);
if (ctls.Length > 0 && ctls[0] is TextBox)
{
    TextBox tb = (TextBox)ctls[0];
    // .. do something with "tb" ...
    tb.Text = "hello!";
}

字符串
请注意，如果您为组输入两位数，则当前命名约定可能会导致错误的TextBox。
要解决这个问题，你可以在数字中使用前导零，或者用另一个字符（如.或_）分隔它们：

tb_Stress040301

tb_Stress.4.3.1

tb_Stress_4_3_1
