ExtractToFile抛出访问被拒绝错误？

Question

首先,我清楚我使用ASP.NET 4.5和DefaultAppPool(集成4.0).我还配置了对DefaultAppPool用户的匿名访问.我已经授予了对DefaultAppPool的所有访问权限.System.Security.Principal.WindowsIdentity.GetCurrent()方法给我相同的用户.但是当下一行运行时,它给了我Access to the path 'XXXX' is denied.例外.然后出于测试目的,我已经授予EveryOne用户所有权利,但仍然得到相同的错误.这是代码行.注意桁架

        using (ZipArchive archive = new ZipArchive(zipStream))
        {
            foreach (ZipArchiveEntry file in archive.Entries)
            {
                file.ExtractToFile(location,true);
            }
        }

这是StackTrace,

在这种情况下,.NET框架给了我错误的异常.问题是,我只是传递位置(没有文件名的文件夹位置).所以在包含完整路径后,这是有效的.
