【问题描述】：
我正在尝试学习 ASP.NET（经过多年使用经典的 ASP、jQuery、Ajax 等）。我已经安装了 VS 2010，并且在我的 W7 64 位 PC 上运行了 IIS。
我创建了一个名为 ASP.NET-4.0 的新 Web 项目（在名为 C:\ASP.NET Testing\ASP.NET 4.0 示例的文件夹中）。
我可以很好地编译项目并运行默认页面等。
我正在尝试从书中加载一个简单的示例（ASP.NET 4.0 In Practice）。所以，我创建了一个子文件夹 CH01，然后复制到 .aspx 和 .aspx.vb 文件中。
当我调试这个时，我得到了
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'ASP.NET_4._0.Global_asax'.
Source Error:
Line 1: <%@ Application Codebehind="Global.asax.vb" Inherits="ASP.NET_4._0.Global_asax" Language="vb" %>
在浏览器窗口中。
示例代码（已从网站下载）是：
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="1-4.aspx.vb" Inherits="_1_4" %>
<html>
<head>
<title>Listing 1.4</title>
</head>
<body>
<form id="Form1" runat="server">
<div>
<asp:literal id="ResponseText" runat="server" />
<br />
Enter your name:
<asp:textbox runat="server" ID="Name" />
<br />
<asp:button runat="server" Text="Click Me" ID="ClickButton" OnClick="HandleSubmit" />
</div>
</form>
</body>
</html>
和
Partial Class _1_4
Inherits System.Web.UI.Page
Sub HandleSubmit(ByVal sender As Object, ByVal e As EventArgs)
ResponseText.Text = "Your name is: " & Name.Text
End Sub
End Class
在 VS 中，我还收到一条错误消息，突出显示 ResponseText.Text = "Your name is: " & Name.Text
'ResponseText' is not declared. It may be inaccessible due to its protection level.
Global.asxa 文件
Imports System.Web.SessionState
Public Class Global_asax
Inherits System.Web.HttpApplication
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
' Fires when the application is started
End Sub
Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
' Fires when the session is started
End Sub
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
' Fires at the beginning of each request
End Sub
Sub Application_AuthenticateRequest(ByVal sender As Object, ByVal e As EventArgs)
' Fires upon attempting to authenticate the use
End Sub
Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
' Fires when an error occurs
End Sub
Sub Session_End(ByVal sender As Object, ByVal e As EventArgs)
' Fires when the session ends
End Sub
Sub Application_End(ByVal sender As Object, ByVal e As EventArgs)
' Fires when the application ends
End Sub
End Class
我显然错过了一些非常简单的东西，但我不明白。我看不到任何关于我需要在 VS 中设置的任何说明。
谢谢。
如果我从 VS 添加，此页面可以正常工作。实际上与我从示例中复制的页面相同，但页面标记略有变化。它还有一个由VS自动生成的.designer.vb页面。
