我怎样才能知道，如果一个文件完成了通过FTP？ [英] How can I tell if a file has finished being FTPed?

问题描述

我们有一个C＃Windows服务轮询等待FTP'ed文件的文件夹中发布。为了避免使用文件时仍然被写入它，我们先尝试获取有关文件的锁，但是，有似乎场合，我们正在对文件锁在创建后的FTP'ed文件，但之前对文件进行写入，所以我们最终打开一个空文件。

We have a C# Windows service polling a folder waiting for an FTP’ed file to be posted in. To avoid using the file when it is still being written to we attempt to get a lock on the file first, however, there seems to be occasions where we are getting a lock on the file after the FTP’ed file is created but before the file is written to, so we end up opening an empty file.

是否有可靠的反正告诉如果FTP是完整的？

Is there a reliable anyway to tell if the FTP is complete?

怎么样使用文件夹的专家以指数内容，如果一个文件大小不5分钟之内改变你几乎可以-多少保证上传已经完成。

What about using a folder watcher to index the contents and if a files size does not change within 5 mins you can pretty-much guarantee the upload has been finished.

的时间了，可以连接到您的FTP服务器的超时时间。

The time out could be tied to the timeout of your FTP server to.
