Question

我在按钮上单击面板内部和存储编号创建动态文本框并且想要检索它的文本并总计那个数字我该怎么做？

以下是我生成文本框的代码

        private void btnMaterialAdd_Click(object sender, EventArgs e)

        {
            TextBox[] txtTeamNames = new TextBox[100];
            txtTeamNames[i] = new TextBox();
            string name = "TeamNumber" + i.ToString();
            txtTeamNames[i].Location = new Point(1,  i * 30  );
            txtTeamNames[i].Width = 30;
            txtTeamNames[i].Name = "ID" + i;
            txtTeamNames[i].Visible = true;
            int num = i + 1 ;
            txtTeamNames[i].Text = num.ToString();
            panel1.Controls.Add(txtTeamNames[i]);

        }

如何计算每个文本框的总值并显示？

摆脱数组并使用类级别的列表（不是方法中的局部变量）：

    private List<TextBox> TextBoxes = new List<TextBox>();

    private void btnMaterialAdd_Click(object sender, EventArgs e)
    {
        TextBox tb = new TextBox();
        int i = TextBoxes.Count + 1;
        tb.Location = new Point(1, i * 30);
        tb.Width = 30;
        tb.Name = "ID" + i;
        tb.Text = i.ToString();
        TextBoxes.Add(tb);
        panel1.Controls.Add(tb);
    }

现在你可以迭代那个列表来获得总数：

    private void btnTotal_Click(object sender, EventArgs e)
    {
        int value;
        int total = 0;
        foreach (TextBox tb in TextBoxes)
        {
            if (int.TryParse(tb.Text, out value))
            {
                total = total + value;
            }
            else
            {
                MessageBox.Show(tb.Name + " = " + tb.Text, "Invalid Value");
            }
        }
        MessageBox.Show("total = " + total.ToString());
    }
