static void OpenConnection(string connectionString)
{
   using (OleDbConnection connection = new OleDbConnection(connectionString))
   {

      {
         connection.Open();
         Console.WriteLine("ServerVersion: {0} \nDatabase: {1}",
             connection.ServerVersion, connection.Database);
      }
      catch (Exception ex)
      {
         Console.WriteLine(ex.Message);
      }
      // The connection is automatically closed when the
      // code exits the using block.
   }
}
Public Sub OpenConnection(ByVal connectionString As String)

   Using connection As New OleDbConnection(connectionString)
      Try
         connection.Open()
         Console.WriteLine("Server Version: {0} Database: {1}", _
             connection.ServerVersion, connection.Database)
      Catch ex As Exception
         Console.WriteLine(ex.Message)
      End Try
      ' The connection is automatically closed when the
      ' code exits the Using block.
