To avoid this - do at little work as possible in OnChanged handler and do all heavy work in separate thread, for example (not production ready code, just for illustation purposes): var queue = new BlockingCollection(new ConcurrentQueue()) įoreach (var item in queue.GetConsumingEnumerable()) ) That means if you do a lot of work in a handler - buffer has much higher chance of being overflowed. Your OnChanged handler is called and only when it is finished - notification is removed from that buffer. Next (and maybe even more important) is how this buffer is cleared. You can increase that buffer by setting InternalBufferSize to 64 * 1024 (64KB, max allowed value). This causes the component to lose track of changes in the directory If there are many changes in a short time, the buffer can overflow. EachĮvent can use up to 16 bytes of memory, not including the file name. The system notifies the component of file changes, and it stores thoseĬhanges in a buffer the component creates and passes to the APIs.

FOLDERWATCH CODE
The code I have works fine if I add only a few xml's at a time however when I trying to dump a large number into the folder fileSystemWatcher is not processing all of them. xml files contain an email address and a path to a image which once read will be emailed. xml files using fileSystemWatcher being called from a method called folderWatch.
I'm new the c# and am writing a program that will monitor a folder for.
