Question

我在面板中有一张桌子。该表有32行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。没有文本框是必需的，因此用户可以选择不输入任何内容。输入完成后，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。那么如何读取每个保存的行进行计算？这就是我如何使用列表int或List字符串保存在会话中以及如何计算会话中输入的数据。数据库中没有保存任何内容。 示例代码

Answer 1

假设您正在使用ASP.NET Web Forms？

如果您启用了Viewstate，则文本框将在某些情况下保留值。

你的下一个按钮会有某种与你的代码绑定的OnClick功能吗？

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价值。然后，您可以将该值存储在Session中，以保持值的存活。

如何保存在文本框中输入的数据，以后用于在单击下一个按钮时进行计算
