示例1: WatchForChanges
public static IObservable<string> WatchForChanges(string path,string filter,bool recursive)
{
var isDirectory = new DirectoryInfo(path).Exists;
recursive = isDirectory && recursive;
var fileSystemWatcher = new FileSystemWatcher(path)
{
Filter = filter,
IncludeSubdirectories = recursive
};
fileSystemWatcher.EnableRaisingEvents = true;
var observable = fileSystemWatcher.AsObservable()
.ObserveOn(TaskPoolScheduler.Default)
.Select(e => e.FullPath)
.Buffer(TimeSpan.FromSeconds(1))
.Where(e => e.Any())
.Select(e => e.Distinct())
.SelectMany(e => e);
var connectableObservable = observable.Publish();
connectableObservable.Connect();
connectableObservable.Subscribe((v) => log.Info("Detected file system change, root: {0}, change: {1}",path,v), (ex) => fileSystemWatcher.Dispose(), fileSystemWatcher.Dispose);
return connectableObservable;
}
