>                    IsolatedStorageScope.Domain,

>                    FileAccess.Read,
>                    FileShare.Read);
>
>                try
>                {
>
>                    SafeFileHandle aFileHandle = isoStream.SafeFileHandle;
>                    Console.WriteLine("A pointer to a file handle has been
>obtained. "
>                        + aFileHandle.ToString() + " "
>                        + aFileHandle.GetHashCode());
>                }
>
>                catch (Exception e)
>                {
>                    // Handle the exception.
>                    Console.WriteLine("Expected exception");
>                    Console.WriteLine(e);
>                }
>
>                StreamReader reader = new StreamReader(isoStream);

>To send it as an email attachment, we may first write it to disk as a
