Use FileSystemWatcher on a single file in C#
提问by Jimmy
When i try to set the watcher path to a single file like so:
当我尝试将观察者路径设置为单个文件时，如下所示：
watcher.Path = filePath1;
I get the error:
我收到错误：
The directory name C:\Cromos 3.0\repository\diagnostics\dwm01_2011_06_13__09_03.LXD is invalid.
Can you only set the path to a folder directory?
你只能设置文件夹目录的路径吗？
采纳答案by Steve
Your error is setting the Path property with a full filename
您的错误是使用完整文件名设置 Path 属性
watcher.Path = Path.GetDirectoryName(filePath1);
watcher.Filter = Path.GetFileName(filePath1);
should work.
应该管用。
Not related to your proper question, but, of course, as stated in below comments, it is imperative to set the EnableRaisingEventsproperty to true to enable the FileSystemWatcher's functionality
与您的正确问题无关，但是，当然，如下面的评论所述，必须将EnableRaisingEvents属性设置为 true 以启用 FileSystemWatcher 的功能
回答by Justin Harvey
Yes, but you can watch for specific files by setting the filter property to the filename.
是的，但是您可以通过将过滤器属性设置为文件名来监视特定文件。
e.g.
例如
watcher.Filter = "dwm01_2011_06_13__09_03.LXD";
