如何检查vb.net中是否已下载文件

how to check file already downloaded or not in vb.net

推荐答案

如果您控制了发送服务，则可以使用标记文件来实现.如果发送服务会例如完成后编写一个".finished"文件，您可以等待该文件出现.

If you had control over the sending service, you would implement this using marker files. If the sending service would e.g. write a ".finished" file when it''s done, you could wait for that file to appear.
