I have tried to have it run as a service but the application doesn't react to downloads.

推荐答案

您可以使用C＃中的文件系统观察程序类来检测新文件下载。



FileSystemWatcher类（System.IO） [ ^ ]



通过以下活动，您可以执行以下任何操作文件被更改/更新/删除。

You can use the file system watcher class in C# to detect new file downloads.

FileSystemWatcher Class (System.IO)[^]

With the following events, you can do anything you need when a file is altered/updated/deleted.

watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);

请记住，这必须作为Windows服务实现，以持续监控目录。



我提供的链接提供了您需要做什么的示例使FileSystemWatcher类工作。

Keep in mind this would have to be implemented as a windows service to continuously monitor a directory.

The link i provided provides samples for what you need to do to make FileSystemWatcher class work.
