Connecting to an mdb file using OdbcConnection in VS2013

问题

I am trying to connect to an mdb file from C# 2013 using OdbcConnection. I used to have Office 2000 on my Windows 7 and Windows 8 machines, but I have upgraded to Office 2013 on both and it now longer works on either. My database is still in mdb format.

Here's the code:

const string myConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Path\Mydb.mdb";
OdbcConnection connRL = new OdbcConnection();
connRL.Open();

Whatever I have tried I get the following error:

ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

I have Installed the "Microsoft Access Database Engine 2010 Redistributable" and the "2007 Office System Driver: Data Connectivity Components" but neither of them have made any difference. I can create a new Data Source from the VS 2013 Project menu and that all works at design time.

When I create a blank udl file and double click on it and go to the provider tab there's nothing listed about Access or Jet, but I can see the providers in the registry at HKEY_CURRENT_USER\Software\Microsoft\VWDExpress\12.0_Config\DataProviders. Why aren't they there?

What else can I do to get this to work? I have tried everything I can think of.

I assume you can't connect to the mdb through OdbcConnection. Anyway, to connect to the DB you must specify the connection string on your connection object which is not specified in your code.

To access mdb use code like this:

const string myConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Path\Mydb.mdb";
using(var connRL = new OleDbConnection(myConnectionString))
{
    //use your connection
}
