Question

I been trying to fix this problem for the whole day, but no matter what I do I keep on getting the same exception: UnauthorizedAccessException was unhandled at line
using (Package package = Package.Open(d.FullName, FileMode.Create, FileAccess.ReadWrite))

The full code is:

NTAccount act = new NTAccount("c9lu-PC","c9lu");

DirectoryInfo d = System.IO.Directory.CreateDirectory(path);

DirectorySecurity security = d.GetAccessControl();

security.AddAccessRule(new    FileSystemAccessRule(act,FileSystemRights.FullControl,InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow));

d.SetAccessControl(security);

using (Package package = Package.Open(d.FullName, FileMode.Create, FileAccess.ReadWrite))     // where the exception occurs
{

    PackageHelper.createPart(package, "/pages.zip" , MediaTypeNames.Application.Zip,
                    (stream) =>
                    {
                        using (var parts = ZipPackage.Open(stream, FileMode.Create))
                        {
                        }
                    }

                    );
}

I really don’t know what the problem is, please help me out.

Could it have something to do with the fact that you’re passing in a directory into the first parameter of Package.Open instead of a file name? Should be more like this:

// This gives you a directory object. It's all a directory/folder. No File.
DirectoryInfo d = System.IO.Directory.CreateDirectory(path);

// So use the Combine method to create a full path to a file
string fileName = System.IO.Path.Combine(d.FullName, "pages.zip");

...
// Then use that full path to create the Package.
Package.Open(fileName, ...
