Question

First of all, I clear that I am using ASP.NET 4.5 with DefaultAppPool(integrated 4.0). I have also configured Anonymous Access to DefaultAppPool user. I have given all access to DefaultAppPool. System.Security.Principal.WindowsIdentity.GetCurrent() method give me the same user. But when the following line runs it gives me Access to the path 'XXXX' is denied. exception. Then for testing purpose, I have given all rights to EveryOne user but still getting the same error. Here is the line of code. Note the trus

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

Here is the StackTrace,

[UnauthorizedAccessException: Access to the path 'XXX' is denied.]

Answer 1

.NET framework in this case giving me the wrong exception. The problem was that, I was just passing location(folder location without file name). So after including complete path, this works.
