开发一些中小型软件时，通常都采用 Access 数据库，因为 Access 数据库体积小、比较方便。但该数据库的安全性比较低，为了防止非法 用户的入侵，通常需要为该数据库设置密码，以确保数据库中数据的安 全。本实例将对如何使用 C#连接加密的 Access 数据库进行详细讲解。(When developing some small and medium software, the Access database is usually used, because the Access database is small and convenient. But the security of the database is relatively low. In order to prevent the invasion of illegal users, we usually need to set up passwords for the database to ensure data security in the database. This example will explain how the Access database encrypted with C# connections will be explained in detail.)
