MS Access数据库的Vb.net连接字符串

Question

在VB.net中用于连接MS Access 2010（.accdb）数据库的连接字符串是什么。

Answer 1

connectionstrings.com is a wonderful thing :

Standard security

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\myFolder\\myAccess2007file.accdb;Persist Security Info=False;

With database password

This is the connection string to use when you have an Access 2007 database protected with a password using the "Set Database Password" function in Access.

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\myFolder\\myAccess2007file.accdb;Jet OLEDB:Database Password=MyDbPassword;

Some reports of problems with password longer than 14 characters. Also that some characters might cause trouble. If you are having problems, try change password to a short one with normal characters.

DataDirectory functionality

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\\myAccess2007file.accdb;Persist Security Info=False;

Answer 2

您可以使用Visual Studio的Server Explorer来获取连接字符串或查看连接字符串。

Answer 4

Did you connect to the database by using 'Tools->Connect to database' ?

If you have already done the above, try this:

Go to server explorer. And select connected database -> In its properties there is a connection string -> Copy it and paste into your code.
