推荐答案

将数据库添加到服务器资源管理器，并从其属性中获取连接字符串.

Add your database to your server explorer and get the connection string from its properties.

您可以使用 Application.UserAppDataPath [

you can use Application.UserAppDataPath[^] for this purpose. You need to place your mdb in the respective folder. go throgh the url you will find all the details and sample.

将数据库放入bin/Debug文件夹，然后像这样==>
进行访问

Place your database in bin/Debug folder then access it like this ==>

private String ConStr = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=Product.mdb;Persist Security Info=False;";
