what is the C# code to read types.cursortypes in procedure

Question

I have a stored procedure like this

PROCEDURE PRC_ABCD_GETALL (resultset_out OUT TYPES.cursorType)
AS
BEGIN
OPEN
resultset_out FOR SELECT * FROM ABCD;
END PRC_ABCD_GETALL;

And my C# code is

using (OracleConnection conn = new OracleConnection(cnn))
{
   conn.Open();
   OracleCommand cmd = new OracleCommand();
   cmd.Connection = conn;
   cmd.CommandText = "PRC_ABCD_GETALL";
   cmd.CommandType = CommandType.StoredProcedure;
   cmd.Parameters.Add("resultset_out", OracleType.Cursor, ParameterDirection.Output);
   OracleDataReader rdr = cmd.ExecuteReader();
   while (rdr.Read())
   {
      result.Add(Construct(rdr));
   }
}

but I'm getting error 'OracleDbType' does not contain a definition for 'Cursor' in

OracleType.Cursor. Any solution for this??
