Code Behind variable is not accessible from .aspx page
Question
I have a variable in an aspx.cs page called VersionNumber:
namespace App_name
{
public partial class Default : System.Web.UI.Page
{
public string VersionNumber = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
This variable should be accessible in the .aspx page like such, but instead there is a red squiggly line telling me it doesn't exist in this context:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="App_name.Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>App Name <%=VersionNumber %></title>
<script type="text/javascript" src="scripts/jquery-1.12.4.js"></script>
<script type="text/javascript" src="bs/js//bootstrap-typehead.js?<%=VersionNumber %>"></script>
<script type="text/javascript" src="scripts/Default.js?<%=VersionNumber %>"></script>
<script type="text/javascript" src="scripts/Helper.js?<%=VersionNumber %>"></script>
etc.
How can I make VersionNumber accessible in the .aspx page? thanks

我的问题的解决方案是在 aspx 页面的 Inherit 部分编写命名空间以及类名，如下所示：
Inherits="Solution_History.Default"

I have tested your code and come to the following solutions:
The cs file should be like this without a change to the aspx page:
namespace Solution_History
{
public partial class Default : System.Web.UI.Page
{
public string VersionNumber = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
Not adding the namespace to the cs file then the first line in the aspx should be:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %
I've tried both possibilities and both showed version numbers.
Hope this helps.
