I get the following exception when accessing any URL (route) after a recycle of the App Pool on an otherwise trouble-free ASP.NET MVC 3 web application that is under heavy use.
在一个没有问题的ASP上，在应用程序池被回收后，当访问任何URL(路由)时，我得到以下异常。正在大量使用的netmvc 3 web应用程序。
The facts:
事实说话:
- IIS 7
- IIS 7
- .NET 4.0 Classic Mode Application Pool (only application in the pool)
- .NET 4.0经典模式应用程序池(仅在池中应用)
- accessed via HTTPS as a back-end web-service by other applications
- 通过HTTPS作为后端web服务通过其他应用程序访问。
- no code changes, site was undergoing regular 29 hour automatic recycles on the same code for years, automatic recycle is now disabled to keep the site up
- 没有代码更改，站点正在进行定期29小时的自动回收，在相同的代码上进行多年，自动回收现在被禁用以保持站点的正常运行
- App Pool recycle (or server restart) causes the site to fail
- 应用程序池回收(或服务器重新启动)导致站点失败
- Must redeploy site (copy all files/folders from pre-compile build into physical path) to get it working again after a recycle
- 必须重新部署站点(将预编译的所有文件/文件夹复制到物理路径中)以使其在循环后再次工作?
- we are catching/logging the error in the Application_Error method
- 我们正在捕获/记录Application_Error方法中的错误
- No unhandled exceptions in event log
- 事件日志中没有未处理的异常
- Any attempt to access any route/URL generates the exception
- 任何访问任何路由/URL的尝试都会产生异常。

To debug CheckFileExists, you may wanna use something like this:
要调试CheckFileExists，您可能需要使用以下内容:
string fileName = "Test.aspx";
bool IsExistFile = System.IO.File.Exists(Server.MapPath("./") + fileName);
if (IsExistFile)
Response.Write("Find the file!");
else Response.Write("The file is not exist!");
