.cs文件编译成.dll文件出错
所用工具vs2005
想把App_Code文件下的两个自定义类:CardUser.cs、CardInfo.cs文件编译成两个dll文件：CardUser.dll、CardInfo.dll,并放在bin目录下.
现在的问题是:CardUser.cs已编译成功为CardUser.dll，可是CardInfo.dll手动编译总是提示如下错误:
e:\card\App_code\CardInfo.cs <56,17> :error CS0246
找不到类型或命名空间名称 "CardUser " <是否缺少using指令性或程序集的引用>
但是我引用了已经。
以下是CardInfo.cs的代码:

view.DataSource = Get_Sname(Trans);

view.DataBind();

return list;

HttpContext.Current.Response.Write( " <script language= 'javascript '> alert( ' "+index+ " ') </script> ");
}
}




[解决办法]
加引用得加上csc /r:CardUser.dll　CardInfo.cs
