Try setting up a connection in VS with the Server Explorer pane:
1) Open Server Explorer.
2) Right click "Data connections" and select "Add connection"
3) In the dialog that follows, select your DataSource ("Microsoft Access Database File"), and database, specify the security info, and press the "Test connection" button.
4) When the connection works, press "OK"
5) Highlight your database in the Server Explorer pane, and look at the Properties pane. A working example of the connection string will be shown, which you can copy and paste into your app or config file.

更像是什么：

How about something more like:

public static string strconnection = string.Format(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0}\FDA_DB.mdb", Application.StartupPath.ToString())+";Jet OLEDB:Database Password=12345;";;

public static string strconnection = string.Format(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0}\FDA_DB.mdb;Jet OLEDB:Database Password=12345;", Application.StartupPath.ToString());

你需要ToStri吗？ ng？



您是否应该使用JET？还是ACE？你得到什么错误？

And do you need the ToString?

And should you be using JET? Or ACE? What error do you get?
