Question

好的我有一个相当简单的问题，我想定义一些会话状态变量

到目前为止，在我的代码中，在C＃for aspx页面后面，我在index.aspx.cs文件中可以正常使用以下类型的声明。

Session[Constants.firstName] = "Jordan";

或

Session[Constants.firstName] = 123;

我想从index.aspx文本框中获取文本，而不是这样。

Session[Constants.firstName] = txtb_FName.Text;

问题是将此更改为变量txtb_FName.Text不起作用，当我调试它时，显示局部变量正在填充“”而不是来自我的文本框的输入。

整个CODE路径看起来像这样;
