c# - FileSystemWatcher 事件未触发

Question

我的 FileSystemWatcher 没有抛出任何事件。我看过这些类似的问题，似乎没有一个能解决我的问题:

*编辑:我的目标是捕获 XLS 文件复制到目录或在目录中创建的时间。

• Filesystemwatcher doesn't trigger event
• FileSystemWatcher - event not firing the second time
• FileSystemWatcher Changed event doesn't fire
• FileSystemWatcher - only the change event once firing once?

监控类:

public class Monitor
{
    FileSystemWatcher watcher = new FileSystemWatcher();
    readonly string bookedPath = @"\\SomeServer\SomeFolder\";

    public delegate void FileDroppedEvent(string FullPath);
    public event FileDroppedEvent FileDropped;

    public delegate void ErrorEvent(Exception ex);
    public event ErrorEvent Error;

    public Monitor()
    {
        watcher.Path = bookedPath;
        watcher.Filter = "*.xls";
        watcher.NotifyFilter = NotifyFilters.LastWrite;
        watcher.Changed += new FileSystemEventHandler(watcher_Changed);
        watcher.Error += new ErrorEventHandler(watcher_Error);
    }

    void watcher_Error(object sender, ErrorEventArgs e)
    {
        Error(e.GetException());
    }

    void watcher_Changed(object sender, FileSystemEventArgs e)
    {
        if (e.ChangeType != WatcherChangeTypes.Created) return;
        FileDropped(e.FullPath);
    }

    public void Start()
    {
        watcher.EnableRaisingEvents = true;
    }

    public void Stop()
    {
        watcher.EnableRaisingEvents = false;
    }
}

带列表框的简单表单:

public partial class Form1 : Form
{
    Monitor monitor = new Monitor();

    public Form1()
    {
        InitializeComponent();
        FormClosing += new FormClosingEventHandler(Form1_FormClosing);
        Load += new EventHandler(Form1_Load);
        monitor.FileDropped += new Monitor.FileDroppedEvent(monitor_FileDropped);
        monitor.Error += new Monitor.ErrorEvent(monitor_Error);
    }

    void Form1_Load(object sender, EventArgs e)
    {
        monitor.Start();
    }

    void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        monitor.Stop();
    }

    void monitor_Error(Exception ex)
    {
        listBox1.Items.Add(ex.Message);
    }

    void monitor_FileDropped(string FullPath)
    {
        listBox1.Items.Add(FullPath);
    }
}

我做错了什么？

试试这个。为我工作一个非常相似的任务。

watcher.NotifyFilter = NotifyFilters.FileName;   
watcher.Created += new FileSystemEventHandler(handler);     
watcher.Renamed += new RenamedEventHandler(handler);
