Getting output from DBMS_OUTPUT.GET_LINES() using c#

I know how to get output from DBMS_OUTPUT.GET_LINE().

You can refer http://oradim.blogspot.com.tr/2007/05/odpnet-tip-retrieving-dbmsoutput-text.html

On this page getting output form DBMS_OUTPUT.GET_LINES() method is also explained by using ODP.Net. Is there any way to manage this using only ADO.NET.

For example, how can I read all outputs from below

begin 
 declare 
   stage number := 0; 
   begin
    DBMS_OUTPUT.PUT_LINE('STARTING:'); 
    INSERT INTO Country ( code, name) VALUES (1 , 'xxxx');
    INSERT INTO City ( code, name) VALUES (1 , 'yyyy');
    DBMS_OUTPUT.PUT_LINE('DONE:'); 
COMMIT; 

EXCEPTION  -- exception handlers begin 
  WHEN OTHERS THEN  -- handles all other errors 
   DBMS_OUTPUT.PUT_LINE('Error occured, rollback...');  
   DBMS_OUTPUT.get_LINE(:1, :2);
   stage := -1;
   ROLLBACK; 
  end;
end; 

Output should be like this:

STARTING
DONE

I have this code block, but it returns only first output line

using (OracleCommand cmd = cnn.CreateCommand())
{
    OracleParameter status = new OracleParameter(":1", OracleType.VarChar, 32000);
    p_line.Direction = ParameterDirection.Output;

    OracleParameter line = new OracleParameter(":2", OracleType.Double);
    p_status.Direction = ParameterDirection.Output;  

    cmd.CommandText = script;
    cmd.CommandType = CommandType.Text;
    cmd.Parameters.Add(status);
    cmd.Parameters.Add(line );
    cmd.ExecuteNonQuery();

    string status = status.Value.ToString();
    string line = line.Value.ToString();
}

Output:

STARTING
