Question

I am exporting a gridview to MS Access but I am facing some problems.

What namespace I should be using while creating a MS access database in C#?

Answer 1

要使用Microsoft Office认证的文档（例如MS-Access或MS-Excel）进行播放，您需要添加

using System.Data.OleDb

Answer 2

write some code

OleDbConnection conn = new OleDbConnection();

then right click on the class name (eg OleDbConnection) and select resolve or you can use shortcut ctrl + .

In this specific case you need to add

using System.Data.OleDb

Answer 3

You need to add reference to this namespace in your project System.Data.OleDb

and then use it on you file like this

using System.Data.OleDb
