PC的智能设备路径Visual c＃ [英] Smart Device path to PC Visual c#

问题描述

我在将智能设备应用程序中的数据导入到其连接的PC时出现问题，数据库文件是sqlserverce.sdf文件，我可以导入这个，如果我直接将数据库文件从设备移动到计算机本身的位置，如C：\ Program Files \ Databasename.sdf



但是当它仍然在设备中时试图打开数据库会给我带来很多麻烦，我使用system.IO找到了设备本身的执行应用程序路径，它给了我一个结果\ Program\Databasefolder，我添加了\Programs \Databasefolder \Databasename.sdf



但是仍然无法正常工作，PC的完整路径是Computer \ Devicename \程序\Databasefolder \Databasename.sdf并且它不能正常工作



并且如上所述将文件移动到c：\programfiles \ databasename.sdf使连接字符串工作。

ex：



SqlCeConnection connect = new SqlCeConnection（@Data Source = C：\Program Files \ databasename.sdf ）;





如何从PC应用程序中找到并使用设备本身的完整路径？

I'm having problems importing data in a smart device application into the pc that it's connected to, the database file is an sqlserverce.sdf file, I can import this if I were to directly move the database file from the device into a location in the computer itself, like C:\Program files\Databasename.sdf

but trying to open the database while it's still in the device is causing me a lot of trouble, I located the executing applications path in the device itself using system.IO which gave me a result \Programs\Databasefolder, to which I added \Programs\Databasefolder\Databasename.sdf

but still does not work, the full path from the pc is Computer\Devicename\Programs\Databasefolder\Databasename.sdf and it does not work as well

and as stated moving the file to c:\programfiles\databasename.sdf makes the connection string work.
ex:

SqlCeConnection connect = new SqlCeConnection(@"Data Source = C:\Program Files\databasename.sdf");


How do I locate and use the full path from the device itself from the PC application?

推荐答案

您可能需要更改连接字符串：对于外部设备，我希望它类似于

You probably need to change the connection string: for an external device I would expect it to be something like

SqlCeConnection connect = new SqlCeConnection(@"Data Source = \\DEVICENAME\Programs\Databasefolder\Databasename.sdf ");

首先浏览文件：使用Windows资源管理器查看左侧的网络节点。如果你到达设备，浏览到该文件并单击Windows资源管理器的地址栏 - 这将为您提供可以复制和粘贴的实际文件夹路径。直到你可以在那里找到它，你有可能无法访问该文件！

Start by browsing to the file: use Windows Explorer and have a look via the "Network" node on the left. If you get to the device, browse to the file and click in the address bar of Windows Explorer - that will give you an actual folder path you can copy and paste. Until you can find it there, the chances are you can't access the file!
