Hi..

I have a situation where an application will save an image file in a specific directory. I need to find out whether or not the image file is saved completely. The application can not be modified to fire an event or pass a message to my application. I need to observe the directory and find out whether the image is copied fully or not.

Quick response is appreciated.
Thanks in advance. :)

推荐答案

您想使用FileSystemWatcher对象进行研究.在CodeProject上有很多关于它的文章.

You want to look into using the FileSystemWatcher object. There are a lot of articles here on CodeProject about it.

如果文件被完全保存，
可以在写入模式下打开它(由您的应用程序...):-D

If a file is saved completely,
it can be opened (by your app) in write-mode... :-D
