You need to use the Command object:

OracleCommand objCmd = new OracleCommand();
objCmd.Connection = objConn;
objCmd.CommandText = "count_emp_by_dept";
objCmd.CommandType = CommandType.StoredProcedure;
objCmd.Parameters.Add("pin_deptno", OracleType.Number).Value = 20;
objCmd.Parameters.Add("pout_count", OracleType.Number).Direction = ParameterDirection.Output;
