{
    string connectionString = "Driver={SQL Native Client};Server=(local);Trusted_Connection=Yes;Database=AdventureWorks;";

    using (OdbcConnection connection = new OdbcConnection(connectionString))
    {
        connection.Open();
        Console.WriteLine("ServerVersion: " + connection.ServerVersion
            + "\nDatabase: " + connection.Database);

        // The connection is automatically closed at
        // the end of the Using block.
    }
}

Public Sub CreateOdbcConnection(connectionString As String)
       Using connection As New OdbcConnection(connectionString)
           With connection
               .Open()
               Console.WriteLine("ServerVersion: " & .ServerVersion _

           End With

End Sub

Remarks
