我在edtFTPnet的开发者指南中看到如下说明,也许对你有用:
If supported by the FTP server,the size() command can be used to datermine the size (in bytes) of a remote file.Similarly,the ModTime() can determine the modification time of a remote file,if supported.The returned DateTime is in GMT.
大意就是说:如果FTP服务器支持,就可以用size和ModTime命令来得到文件尺寸和修改日期。
