  insertCommand.ExecuteNonQuery();

  MySqlCommand selectCommand = new MySqlCommand("SELECT f_binary, f_varbinary FROM autotest.simple_types", connection);

  using (MySqlDataReader reader = selectCommand.ExecuteReader())
    while (reader.Read())

        MySqlBinaryString value = reader.GetMySqlBinaryString(i);
        value.Encoding = encoding;
        Console.WriteLine(value);

  Dim buffer2 As Byte() = encod.GetBytes("test2")
  insertCommand.Parameters.Add("p1", New MySqlBinaryString(buffer1, encod))
  insertCommand.Parameters.Add("p2", New MySqlBinaryString(buffer2, encod))
  insertCommand.ExecuteNonQuery()
  Dim selectCommand As New MySqlCommand("SELECT f_binary, f_varbinary FROM autotest.simple_types", connection)
  Using reader As MySqlDataReader = selectCommand.ExecuteReader
    Do While reader.Read
      For i As Integer = 0 To reader.FieldCount - 1
        Dim value As MySqlBinaryString = reader.GetMySqlBinaryString(i)
        value.Encoding = encod
