wp7中如何获取设备ID和用户ID

private static readonly int ANIDLength = 32;  

        private static readonly int ANIDOffset = 2;  



  

        //需要在WMAppManifest  中添加 ID_CAP_IDENTITY_DEVICE  权限,并且用户在marketplace下载程序的时候会有提示

        public static byte[] GetDeviceUniqueID()  

        {  

            byte[] result = null;  

            object uniqueId;  

            if (DeviceExtendedProperties.TryGetValue("DeviceUniqueId", out uniqueId))  

                result = (byte[])uniqueId;  

            return BitConverter.ToString(result, 0, result.Length);

        }  

  

        // 需要在WMAppManifest  中添加 ID_CAP_IDENTITY_USER  权限,并且用户在marketplace下载程序的时候会有提示

        public static string GetWindowsLiveAnonymousID()  

        {  

            string result = string.Empty;  

            object anid;  

            if (UserExtendedProperties.TryGetValue("ANID", out anid))  

            {  

                if (anid != null && anid.ToString().Length >= (ANIDLength + ANIDOffset))  

                {  

                    result = anid.ToString().Substring(ANIDOffset, ANIDLength);  

                }  

            }  

  

            return result;  

        }
