如何解决以下问题？
我已将'OldMailsCollection.aspx'中的文件重命名为'StudentOldMail.aspx'。
自动重命名代码隐藏文件。我还更新了参考文献。
但是当我编译解决方案时，会打开一个带有随机名称的文件。该文件来自目录
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
我删除了该文件并再次构建了解决方案。但该文件一次又一次地打开。
显示以下错误消息：
Error 1 ASP.student_studentoldmail_aspx.GetTypeHashCode(): no suitable method found to override c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\web\c0297e2c\521e6c\App_Web_0cva2jmg.6.cs 652

检查aspx页面的@Page指令的Inherits属性，并确保它与代码隐藏中的类名匹配。有时，当它仍然指向旧的类名时会出现此错误。

我不知道究竟是什么导致了这个问题。避免重命名aspx / cs文件对的一种方法是重新创建文件（以新名称），复制并粘贴代码内容+编辑。它对我有用。
