这不是权限问题.问题是我没有检查|DataDirectory|是否确实像应有的那样解析到AppData目录.

It wasn't a permissions problem. The problem is that I didn't check that |DataDirectory| actually resolved to the AppData directory like it's supposed to.

在IIS 7.5服务器上，|DataDirectory|解析为C:\inetpub\wwwroot\AjaxSource\App_Data，但实际的AppData目录是C:\inetpub\wwwroot\AjaxSource\bin\App_Data.

On the IIS 7.5 server, |DataDirectory| resolves to C:\inetpub\wwwroot\AjaxSource\App_Data, but the actual AppData is directory is C:\inetpub\wwwroot\AjaxSource\bin\App_Data.

我使用Fiddler捕获的错误从不提及任何路径，但暗示权限问题.我的其中一个视图使用以下命令显示了已解析的目录:

The errors I caught using Fiddler never mention any paths, but imply a permissions problem. I had one of my views display the resolved directory with:

<h1>@AppDomain.CurrentDomain.GetData("DataDirectory")</h1>

(奇怪的是，此没有记录).
