I am trying to connect to an MS Access 2013 database using the following code.  Why does this not work???

New OleDbConnection(String.Format("Driver={Microsoft Access Driver (*.mdb, *.accdb)}; Dbq={0}; Uid=admin; Pwd=;", inAccessDBName))

Can you correct this?

You either need to use an ODBCConnection class or use the the correct provider for OleDB connection. In case of the former, the connection string will be:
New OdbcConnection(String.Format("Driver={Microsoft Access Driver (*.mdb, *.accdb)}; Dbq={0}; Uid=admin; Pwd=;", inAccessDBName))

Open in new window

If you use the OleDB connection you need to specify the "Microsoft OLE DB Provider for ODBC Drivers" (MSDASQL.1). The complete connection string will be:
New OleDbConnection(String.Format("Provider=MSDASQL.1;Extended Properties=""Driver={Microsoft Access Driver (*.mdb, *.accdb)}; Dbq=c:\test.mdb; Uid=admin; Pwd=;"""", inAccessDBName"))

Open in new window

Please note that you must use double quotes in the connection string.
BTW, the best way to test (and create) OLE DB connection strings is by using a UDL trick. Create an empty text file with UDL extension. Open it. Select a provider on the first tab page and select extended options on the second. Press OK. The file will be saved. Open it with Notepad. The connection string will be inside the file. You can then delete the file
