我在面板中有一张桌子。该表有 32 行和 4 列。一列是标签并有描述。其他 3 个是文本框。用户可以在任何文本框中输入 0 到 99 之间的数字。不需要任何文本框，因此用户可以选择不输入任何内容。输入后，用户将单击下一步按钮，计算将完成并显示在新页面中。在此之前，我想知道如何保存用户输入的所有数据。那么我如何读取每个保存的行来进行计算呢？这是我被困在如何使用列表 int 或列表字符串保存在会话中以及如何计算会话中输入的数据的地方。数据库中没有保存任何内容。 示例代码 

<table class="wizard">

    <tr>
      <td class="blankcell" valign="bottom" align="left" width="39%">
      <span class="smalllabel">Available Service</span></td>

假设你正在使用ASP.NET Web Forms?

如果您已Viewstate启用，则文本框将在某些情况下保留这些值。

您的下一个按钮将具有某种与您的代码相关联的 OnClick 功能，对吗？

protected btnNext_Click(object sender, Eventargs e) {

  var value = txtSpousePreventivePhysicalExam.Text;

}

这就是你如何获得特定文本框的值。然后，您可以将该值存储在其中Session以保持该值有效。
