Zkoušel jsem jednoduchou zpáteční cestu a zdá se, že vše funguje dobře.
void Main()

using (var connection = new OracleConnection("DATA SOURCE=HQ_PDB_TCP;PASSWORD=oracle;USER ID=HUSQVIK"))

connection.Open();
using (var command = connection.CreateCommand())
{
command.CommandText = "DECLARE i SYS.ODCICOST := :p; BEGIN :p := SYS.ODCICOST(i.CPUCOST + 1, i.IOCOST + 1, i.NETWORKCOST + 1, i.INDEXCOSTINFO || 'Dummy'); END;";
command.BindByName = true;
var parameter = command.CreateParameter();
parameter.Direction = ParameterDirection.InputOutput;
parameter.ParameterName = "p";
parameter.OracleDbType = OracleDbType.Object;
parameter.UdtTypeName = "SYS.ODCICOST";
parameter.Value = new OdciCost { CPUCOST = 123, INDEXCOSTINFO = "DUMMY", IOCOST = 456, NETWORKCOST = 789 };
command.Parameters.Add(parameter);
command.ExecuteNonQuery();
var odciCost = (OdciCost)parameter.Value;
Console.WriteLine($"CPUCOST={odciCost.CPUCOST}; IOCOST={odciCost.IOCOST}; NETWORKCOST={odciCost.NETWORKCOST}; INDEXCOSTINFO={odciCost.INDEXCOSTINFO}");
