推荐答案

这有点棘手.首先，您将需要实施长轮询或按Push来实现当今流行的称呼.其他方法是轮询，但是轮询很糟糕..Net有一个很好的异步信令框架，称为 SignalR

This one is a bit tricky. First of all you will want to implement long polling or Push how it's popular to call it nowadays. Other way is polling, but polling sucks. There is a good async signaling framework for .Net called SignalR

第二，您要使用 FileSystemWatcher 监视您的文件夹.

Secondly you'd want to use FileSystemWatcher to monitor your folders.
