如何从asp.net中动态添加的文本框中获取文本？

Question

我现在正在制作一个单词编写器，它将从我的程序中输入的内容中编写一个单词文件。它工作得很好buuut。当我在表格中添加一些文本框时，他们会得到一个单独的名称，但是当我点击保存时，如何选择其中一个并从中获取文本字段？

这是我的表填充

private void filltabel()
    {
        for (int i = 1; i <= ddlServer.SelectedIndex; i++)
        {
            Label label = new Label();
            label.Text = "<h3>Server " + i + "</h3>";
            TableRow trow = new TableRow();
            Table1.Rows.Add(trow);
            TableCell tCell = new TableCell();
            tCell.ColumnSpan = 4;
            tCell.HorizontalAlign = HorizontalAlign.Center;
            trow.Cells.Add(tCell);
            tCell.Controls.Add(label);

            trow.Cells.Add(tCell);
            tCell.Controls.Add(textbox);
        }
        for (int i = 1; i <= ddlPrinter.SelectedIndex; i++)
        {
            Label label = new Label();
            label.Text = "<h3>Printer " + i + "</h3>";
            TableRow trow = new TableRow();

            textbox.ID = "txtPrinterHWModel" + i;
            textbox.Attributes.Add("runat", "server");
            tCell = new TableCell();
            trow.Cells.Add(tCell);

            trow.Cells.Add(tCell);

            label.Text = "IP: ";
            tCell.Controls.Add(label);
            textbox = new TextBox();
            textbox.ID = "txtPrinterIP" + i;
            textbox.Attributes.Add("runat", "server");
            tCell = new TableCell();
            trow.Cells.Add(tCell);
            tCell.Controls.Add(textbox);
            trow = new TableRow();
            Table1.Rows.Add(trow);
            tCell = new TableCell();
            trow.Cells.Add(tCell);
            label = new Label();
            label.Text = "Kommentar: ";
            tCell.Controls.Add(label);
            textbox = new TextBox();
            textbox.ID = "txtPrinterKommentar" + i;
            textbox.Attributes.Add("runat", "server");
            tCell = new TableCell();
            trow.Cells.Add(tCell);
            tCell.Controls.Add(textbox);
        }
    }

基本上对于我的第一个文本框，它将是＆＃34; txtServerServernavn＆＃34; + i其中i == 0。

        for (int i = 0; i < antalserver; i++)
        {
            TextBox test = Request.Params["txtServerServernavn" + i];
            serverArr[i, 0] = test.Text;
        }

现在request.params是我试过的东西，但希望你能理解:) 基本上，我认为我的问题是，所以我必须把它放在那里而不是阅读它？

修改 好吧认为这里需要更多信息。我的程序中有2个下拉框，它们都会向我的table1添加更多表格单元格和行。 现在，当我更改ddl时，它将进行回发，更改应该有多少可见文本框。然后，当我点击保存时，我希望它被发送到docx但它总是只返回null。 -------------------------间隔------------------------ ---------------------------------------

好吧，因为我无法得到任何关于这个问题的帮助，所以我决定使用另一种方法来做这件事。

我现在在不同的表中使用Dokumentation.aspx对其进行硬编码，以减少代码隐藏中的代码。我可以隐藏lable和textboxes，但是在我的代码隐藏中需要更多的代码。

在我的代码隐藏中，我只是为服务器列表运行它。

        Table[] T = new Table[] { Table1, Table2, Table3, Table4, Table5, Table6, Table7, Table8, Table9, Table10 };
        foreach (Table t in T)
        {
            t.Visible = false;
        }
        for (int i = 0; i < ddlServer.SelectedIndex; i++)
        {
            T[i].Visible = true;
        }

这也给了我正在寻找的结果，但现在我可以毫无困难地进入我的桌子
