推荐答案

选项:
1.使用配置(或应用程序设置")
2.从共享文件夹访问数据.
3.始终将数据保留在与主exe相对的位置.
例如:让您的应用程序路径为D:\ MyAppFolder \ myapp.exe
让您的数据路径为D:\ MyAppFolder \ MyData \ SomedatabaseFile.ext
因此，您的数据库可以通过以下方式访问:

Options:
1. Use configuration(or App Settings)
2. Access data from a Shared folder.
3. Always keep data in a relative location to the main exe.
Eg: Let Your application path is D:\MyAppFolder\myapp.exe
Let your data path is D:\MyAppFolder\MyData\SomedatabaseFile.ext
So your DB can be accessed as :

string DBPath = System.IO.Path.Combine(System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "MyData\\Somedb.mdb");
