Connection with two banks in c#

Question

I need to connect to two types of databases, namely: Oracle and Postegre. I need to go to Oracle, generate a spool with some queries and upload this spool in Postegre. Is it possible to do this in C#? I’m having a lot of difficulty finding content related to this theme in forum etc.. Can this code for connection ORACLE:

    class ConsultaBancoOra
    {
        //public Process Sqlpl { get; private set; }
        private string connection = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)" +
            "(HOST=xx.xx.xx.xxx)(PORT=xxxx))) (CONNECT_DATA=(SERVICE_NAME=xx))); User Id=xxxx; Password=xxxxxx";
        //Consulta ORACLE

        public ConsultaBancoOra()
        {
            //String de Conexão
            OracleConnection ora = new OracleConnection(connection);
            //OracleCommand oraComand = new OracleCommand();
            //oraComand = ora.CreateCommand();
            //oraComand.CommandText = " select * from tb_003_ref_fd_dados_carga_base;";
            //oraComand.CommandTimeout = 15;
            //oraComand.CommandType = CommandType.Text;
            MessageBox.Show("Conexão realizada");

                    process.Start();
