Filewatcher quit code#
I've pasted my code below, and welcome any thoughts. bmp file, the destination directory will add a "whatever.txt" file by default. My other challenge is to reflect the file that is being created in the destination directory. It seems I can only get one file to create in the destination directory, and any other new files created are over written. My issue is that I'm trying to setup my File Watcher program so that when new files are added, they are not over written in the destination directory but added. I've read a lot of material on the Microsoft site, and Stack Overflow too, but not finding a solution. The first thing to do is to build a function that returns all files in a directory.Hello Stack Overflow community, I'm still learning the basics of c# and am need of some guidance. Without any further ado, let’s cover the three functions.
A function that highlights differences between two lists.A function that returns a list of files found in a directory.The whole thing can be addressed in three simple functions: Instead of registering to native OS events, we are going to poll a directory for changes. Ultimately, building a simple file watcher is a very straightforward process. These, however, are often unable to support Shared Drives.įor our purposes, we are going to build something very simple that works in all cases, only covering the New File arrival use case. They also often do that through Native OS Events. Generally, file watchers offer functionality for the Creation, Amendment, Deletion, Existence and Rename of files. Unless a file-watcher is in place, someone would manually need to monitor for the arrival of the said file before manually kicking off the relevant daily process. Imagine for instance, that a daily process requires the arrival of a file from another department.
The file-watcher, upon the arrival of any file, will trigger a follow-up process. A file-watcher is a process which monitors a specific directory for the arrival of any files. In this blog, we are going to build from scratch what is known as a ‘File Watcher’.
