CI 自己定义类中怎么加载CI其它的类库

beyondbobo

<?php
class Users{

var $CI;

function Users() {
  $this->CI =& get_instance();
  $this->CI->load->library('session');
}

function del_login_info($type) {

  $this->CI->sess_destroy();


}

}

这样为什么不行，报错
Fatal error: Call to undefined method Users::sess_destroy() in ...

$this->CI->session->sess_destroy();
