Question

I am currently accessing a access 2010 database in c# and its unable to open the database as it doesn’t seem to have the correct driver when I was using a .mdb this worked, but now since I’m using a .accdb it doesn’t seem to want to open the database. Here’s the opening code. I was wondering if there was anything you could help me with?

public void openDatabase(string dbname)
    {
        //dataBaseName = dbname;
        dataBaseName = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=houses.accdb"; //Defines the location of the database and its type.

        connection = new OleDbConnection(dataBaseName); //Creates a new OleDbConnection using the data from dataBase.

        connection.Open(); //Opens the TCP/IP connection.
    }`enter code here`

Answer 1

You need to change:

Provider=Microsoft.Jet.OLEDB.4.0

To

Provider=Microsoft.ACE.OLEDB.12.0
