How to ignore a "Duplicate entry error" in MYSQL and insert the remainder not duplicate

How to ignore a exception and insert the rest of the fields when I get this error in MYSQL using mysql .NET connector? My try catch is as follows:

try
    {
        conexao.Open();
        MySqlDataReader reader = comm.ExecuteReader();
        reader.Read();
        return reader.GetString("ID");

    }
    catch (MySqlException e)
    {
        if (e.Number == 1062) //Duplicate entry
        {
            MySqlDataReader reader = comm.ExecuteReader();
            reader.Read();
            return reader.GetString("ID");
        }
        else
        {
            Debug.WriteLine(Query);
            Debug.WriteLine(e);
            return "Error";
        }

    }
    catch (Exception e)
    {
        Debug.WriteLine(Query);
        Debug.WriteLine(e);
        return "Error";
    }
finally
{

        conexao.Close(); //Fechando a conexão
}

Naturally when I have duplicate emails within the values of my query I fall into the first catch (MySqlException e) within it I started to filter the error by if (e.Number == 1062 it checks and falls right inside that if , however when I go I would like to insert 99 and ignore the email that already exists in the table.
