总是提示：
错误 1 找不到类型或命名空间名称“YuTouWebSite”(是否缺少 using 指令或程序集引用?) D:\Backup\我的文档\Visual Studio 2008\Projects\YuTou\YuTou\User_Index.aspx.cs 11 7 YuTou

。。。。
../App_Code/YuTouCms.cs 中已经有namespace YuTouWebCms
在 User_Index.aspx.cs 中引用using YuTouWebSite;却不行呢。？
请高人指点。。谢谢

Answer 1

你根本就没有YuTouWebSite这个命名空间,只using是不行的,必须存在才行.
