Which one you choose will simply depend on the use-case and what level of support is necessary. For example, if you want to create an auto backup of a folder, you can implement a File system. This class is useful when you need to auto update the updates in a directory. They both get you to the same place, but one requires a bit more hand-holding in exhange for greater customization and safety. C FileSystemWatcher listens to the file system and places a watch on a directory, its subdirecttories, and files and notifies if any changes are made to the directory. Detecting moved files using FileSystemWatcher. The Pros and Cons list between the two solutions is small. The goal is to detect whether or not the computer camera is moving. That saves a call to the On-Call phone and makes everyone happier for it. When the user inspects the logs to find out why their change hasn’t taken effect, the problem will be obvious, and hopefully the solution will to. Great! Now if a user changes the TimerConfig to something that is invalid our OnChanged function will fall into the catch block. _logger.LogError("Config Update Detected, Config file DELETED") Private void OnDeleted(object sender, FileSystemEventArgs e) _fileSystemWatcher.EnableRaisingEvents = true For example, say there is a section of a config.json file we care about specifically. then you may often only need to configure a few options on a component. We initally turned to the IOptionsMonitor interface to detect specific changes and pass them to the appropriate places. Get notified about file events in a directory using. Instead we want to simply edit the configuration without stopping the service, monitor the log for a log message confirming the change has taken affect, then go about our day with no interruption. If we wanted to change this config value from a 60 minute interval to a 120 minute interval we would have to stop the service, edit the configuration file, and restart the service. For example, a configuration setting might inform the application of how often to run a process on a timer. This isn’t a particularly special case, but it was new for us.Īs with most of our C# applications, we provide configuration files that our code deserializes into a C# class to control how the application behaves. Note that I am absolutely certain that the files are being correctly edited and saved externally using Vim.In a recent project, our team decided that we wanted the ability to reconfigure the application settings of a running service without having to restart it. Sometimes it does, but it’s inconsistent! If I revisit the file in Obsidian then changes are sometimes picked up and propagated to sync, but if I forget to do this then the changes are often overwritten by the most recent version to sync back in from my iPad or iPhone (which are both connected to the remote vault via Obsidian Sync). Obsidian is constantly running on my Mac with Obsidian Sync connected to a remote vault, but it often fails to pick up changes. Occasionally users do save files directly into the folder from Excel and I get Cannot open the datafile errors from the task that is being triggered and I. Specifically, my use case is that my main vault is on a Synology network drive, and I often edit these files directly using Vim on a Raspberry Pi. To me this indicates that the bug was never fixed. I found this thread in the Bug Graveyard that seems to describe the problem I’ve been having: File changes made outside Obsidian are not shown (AppImage version) Obsidian version: latest version (not at my computer currently so can’t check, but I keep my installation up to date).So you can't notify on LastWrite AND Size together. Doesn't matter anyway, further reading shows that the filters are not combined in any way. Verified during testing with a test text file.
