因公司要求,整理公司资源,把现有的资源上传的一个电脑上(在一个同事的电脑上腾出了空间,把所有的资源上传的此电脑上),我在这个电脑上装了SQL2008+serv_u+IIS7,我用的是c# winform+webservice,数据库操作通过webservice进行,上传文件用ftp批量上传,上传整个文件夹,一下是文件夹目录
C# ftp 上传、下载、删除
文件夹总大小100MB以上,有时候单独一个文件也有10-100mb左右,
一下是ftp上传代码

可以通过遍历批量上传文件,但是上传速度很慢,很慢。上传一个文件夹都要花上半天,我想问有没有办法提高上传速度,或者要用别的上传方法。(用别的方法也可以,因为ftp上传我第一次接触,不太熟悉)请各位给个意见,小弟感激不尽!还有上传的时候要加上进度条。请各位大侠高手们帮忙。
