推荐答案

在移动设备应用程序开发中，该路径始终相对于移动设备"根目录(仅当您使用ActiveSync连接到设备或仿真器时才显示移动设备"选项)而不是C驱动器.与在运行时一样，使用模拟器或使用"\"作为根路径的设备来启动应用程序.仿真器或设备不知道什么是"C:". ;) 将您的sdf文件保存在"\"侧(也称为我的基于移动设备")，然后提供sdf的路径. 示例:如果您的sdf文件位置如下所示: 在我的电脑内部->移动设备->我的基于Windows Mobile的设备-> <您的文件夹=" name ="> \ YourSdfFile.sdf 然后在应用程序中以这种方式给出路径"\<您的文件夹名称> \ YourSdfFile.sdf" Hi, In mobile device application development, the path is always relative to "Mobile Device" root("Mobile Device" option appears only if you are connected to device or emulator using ActiveSync) instead of C drive. As when at runtime the application is launched using either emulator or device which use "\" as the root path. Emulator or device does not know what is "C:". ;) Keep your sdf file in side "\" ( which is also called "My Mobile Based Device" then provide the path of sdf. Example: If your sdf file location is like following : Inside My Computer --> Mobile Device -->My Windows Mobile Based Device --> <your folder="" name="">\YourSdfFile.sdf Then in application give the path this way "\<Your Folder Name>\YourSdfFile.sdf" String sConnString = @"\MyFolder\sample.sdf"

注意:仅当您使用ActiveSync连接到设备或仿真器时，我的电脑"浏览器中才会显示移动设备"选项.

NB: In My computer explorer "Mobile Device" option appears only if you are connected to device or emulator using ActiveSync.
