如何动态更改oledb连接字符串，以便可用于每个目标计算机？

Question

i am developing a win form project in c#. I am facing a problem, I am using a .mdb db file, and a connection string to use it eg @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Users\\mohan\\Documents\\VisualStudio2010\\Projects\\AotoInformation\\AotoInformation\\common\\appDb.mdb;Persist Security Info=True"

Now I am making an .exe file of my project, but when someone install this .exe to his system, this connection string can't work.

How can I get a connection string that can be used on every target machine, no matter where user install the app?

Answer 1

set the connection string in your code instead of config file. you can find app root path using AppDomain.CurrentDomain.BaseDirectory.

Answer 2

连接字符串只是一个字符串..因此，最初，您可以将其保留为..Data Source=@mdbFilePath..之类的东西..Data Source=@mdbFilePath..当请求连接字符串时，请将@mdbFilePath替换为您的mdb文件路径...
