Exception Details: System.UnauthorizedAccessException: Access to the path 'E:\wlk\pacms\web.Config' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

从错误的信息来看是网站的权限不够，建议给这个文件'E:\wlk\pacms\web.Config' 可读写权限，然后再去试试看。

Access to the path 'E:\wlk\pacms\web.Config' is denied. 禁止访问，看下是否有权限编辑 再看看别人怎么说的。
