环境为:VS2008Team+.net3.5

asp.net 网站前台页面<%= %>这样绑定可以，asp.net Web 应用程序就不可以

示例代码如下：

1.asp.net网站

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>无标题页</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <%=i %>
    </div>
    </form>
</body>
</html>

Default.aspx

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class _Default : System.Web.UI.Page 
{
    internal int i= 12345678;
    protected void Page_Load(object sender, EventArgs e)
    {

    }
}

Default.aspx.cs

2.asp.net Web 应用程序

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>无标题页</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <%=i %>
    </div>
    </form>
</body>
</html>

Default.aspx

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

namespace WebApplication1
{
    public partial class _Default : System.Web.UI.Page
    {
        internal int i = 123456789;
        protected void Page_Load(object sender, EventArgs e)
        {

        }
    }
}

Default.aspx.cs

asp.net Web 应用程序会抱错，错误如下：

编译器错误消息: CS0103: 当前上下文中不存在名称“i”

源错误:


行 10:     <form id="form1" runat="server">
行 11:     <div>
行 12:         <%=i %>
行 13:     </div>
行 14:     </form>
