DataBase用于在只有CF 2.0的Windows手机上存储用户信息？ [英] DataBase for storing userinformation on windows phones which has only CF 2.0?
问题描述
我是Windows移动开发的新手。我正在尝试开发Windows Mobile 5和Windows Mobile 6的应用程序。不幸的是我们不支持Windows phone 7因为我们的应用程序完全依赖于SMS，这在Windows Phone 7上是不可能的
。
Hi, I am new to Windows mobile development. I am trying to develop an application for windows mobile 5 and windows mobile 6. Unfortunately we are not supporting windows phone 7 as our application is completely dependent on SMS which is not possible on Windows phone 7.
我遇到的问题是，我必须在设备数据库或持久内存中存储一些安全的用户信息。我尝试过SqlServerCE并尝试在设备上部署应用程序。但我得到一个错误"MissingMethodException"因为该设备仅具有
.NET CF 2.0，而SqlServerCE仅在.NET CF 3.5中可用。当我们将CF 3.5 .cab文件交付给用户时，我不希望将其包含在我们的应用程序中。因为最终用户不会成为技术人员而且要求
他们安装两个cab文件太多了。即使是我们的客户也不会对这种方法感兴趣。
The issue i am having is, i have to store some secured user information in device data base or persistant memory. I have tried SqlServerCE and tried to deploy application on the device. But i got an error "MissingMethodException" because the device is having only .NET CF 2.0 while the SqlServerCE is available only in .NET CF 3.5. I dont want to include CF 3.5 .cab file in our application when we deliver it to user. Because the end users are not going to be technical persons and it will be too much to ask them to install two cab files. Even our client would not be interested to this approach.
我的问题是，
a） 是否有任何其他可用的DB随附CF 2.0？
a) is there any other DB available which comes with CF 2.0 ?
b）如果将信息存储在文件中是唯一的选择，是否可以通过加密方式保护文件，使其只能由应用程序打开？除了申请本身外，不得以任何其他方式删除该文件。
b) If storing information in a file is the only option, is it possible to secure the file by encrypting in a way that it can be opened only by the application? and also the file must not be deleted by any other means except by the application itself.
提前致谢
推荐答案
AFAIK，SQL CE2.0可以在CF2.0下工作，但它由SQL CE3.0覆盖。所以你需要安装CF3.5
AFAIK, SQL CE2.0 can work under CF2.0, but it covered by SQL CE3.0. So you need to install CF3.5
