本地测试没问题，传到公司专用的测试服务器（虚拟目录）部分文件打开没问题，但Default.aspx及Products.aspx出错了！

错误提示如下：

Compilation Error 
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0433: The type '_Default' exists in both 
'c:\windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\9c906d6a\92fb2bc2\App_Code.0s7vittk.dll' and 'c:\windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\9c906d6a\92fb2bc2\assembly\dl3\58ec9ab0\719b2b05_233bc901\App_Web_60f3aiaz.DLL'

解决：

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

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

上传，测试，成功！
