不要尝试在多用户中使用Access - 你可以为很小的工作而逃脱它，但它只是一个用户数据库这真的不是为多用户访问而设计的，并且当你这样使用时总会给你带来巨大的悲伤。



相反，考虑SQL Server或MySQL - 它们都是多用户，如果您的代码写得很好，那么应该只是将您的类从OleDbConnection和OleDbCommand对象更改为SqlConnection和SqlCommand，或者更改为MySqlConnection和MySqlCommand对象。

然后安装相应的用户的中间服务器上的软件，添加数据库，并从您的应用程序连接到该服务器。

Don't try to use Access in multiuser - you can get away with it for really small jobs, but it's a single user DB that really isn't designed for multiuser access and which always gives huge amounts of grief when you use as such.

Instead, consider SQL Server or MySQL - they are both multiuser, and if your code is well written, it should be just a case of changing your classes from OleDbConnection and OleDbCommand objects to SqlConnection and SqlCommand, or MySqlConnection and MySqlCommand objects instead.
You then install the appropriate software on a central server for the users, add your DB, and connect from your app to that server.
