FileSystemEventHandler的附加参数 [英] Additional parameters for FileSystemEventHandler

问题描述

我正在尝试编写一个程序，该程序可以监视多个文件夹的文件创建并启动相同的操作，但每个文件夹的设置不同.我的问题是为FileSystemEventHandler指定一个额外的参数.我为每个目录创建一个新的FileWatcher来监视和添加Created-action的处理程序:

I'm trying to write a program that could monitor multiple folders for file creations and launch the same action but with different settings for each folder. My problem is in specifying an extra parameter for the FileSystemEventHandler. I create a new FileWatcher for each directory to monitor and add the handler for the Created-action:

foreach (String config in configs)
{
    ...
    FileWatcher.Created += new System.IO.FileSystemEventHandler(FileSystemWatcherCreated)
    ...
}

void FileSystemWatcherCreated(object sender, System.IO.FileSystemEventArgs e, MySettings mSettings)
{
    DoSomething(e.FullPath, mSettings);
}

如何获取传递给FileSystemWatcherCreated()的'mSettings'变量?

How could I get the 'mSettings' variable passed to FileSystemWatcherCreated()?

推荐答案

foreach (String config in configs)
{
    ...
    FileWatcher.Created += (s,e) => DoSomething(e.FullPath, mSettings);
    ...
}
