如何在C＃中使用密码打开访问数据库？

Question

how can I open an MS Access 2007 database with a password in c# ?

I have tried this: Conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\BioDB.mdb ;Password=1966;");

but it doesn't work.

Answer 1

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\mydatabase.mdb;Jet OLEDB:Database Password=MyDbPassword;

From:

http://www.connectionstrings.com/access

And as noted below use @ .

Answer 2

你需要逃避反斜杠，或者在字符串前面加上@ 。

Answer 3

尝试这个：

@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=BioDB.mdb;Jet OLEDB:Database Password=1966;"

Answer 4

This is the connection string to use when you have an Access 2007 - 2013 database protected with a password using the "Set Database Password" function in Access.

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccessFile.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.
