This Enumeration is useful for all the NetShareGetInfo calls such as follows

IntPtr bufptr = IntPtr.Zero;
        int err;
        IntPtr ptr = IntPtr.Zero;
        int output = NetShareGetInfo("<ServerName>", @"<ShareName>", 502, out ptr);
        SHARE_INFO_502 shareInfo = (SHARE_INFO_502)Marshal.PtrToStructure(ptr, typeof(SHARE_INFO_502));
