C# 为什么我的文件系统监视程序不触发事件？

我在一个单独的线程上创建一个FileSystemWatcher来监视目录的更改。当我添加新文件或将新文件复制到我试图监视的目录中时，不会触发任何事件。我已经在Windows窗体应用程序中成功地使用了FileSystemWatcher类，所以我猜我遗漏了一些简单的东西

public partial class MainWindow : Window
{

    System.IO.FileSystemWatcher watcher;
    public MainWindow()
    {
        InitializeComponent();
        System.Threading.Thread t1 = new System.Threading.Thread(MonitorDir);
        t1.IsBackground = true;
        t1.Start();
    }

    private void MonitorDir()
    {

        watcher = new System.IO.FileSystemWatcher("C:\\Temp","*.*");
        watcher.Created += Watcher_Created;
        watcher.Disposed += Watcher_Disposed;
        watcher.Error += Watcher_Error;
        watcher.Changed += Watcher_Changed;
        while (true)
        {

        }
    }

    private void Watcher_Changed(object sender, System.IO.FileSystemEventArgs e)
    {
        throw new NotImplementedException();
    }

    private void Watcher_Error(object sender, System.IO.ErrorEventArgs e)
    {
        throw new NotImplementedException();
    }

    private void Watcher_Disposed(object sender, EventArgs e)
    {
        throw new NotImplementedException();
    }

    private void Watcher_Created(object sender, System.IO.FileSystemEventArgs e)
    {
        throw new NotImplementedException();
    }
}

您需要将其设置为

true

（默认为

false

），否则它不会引发任何事件

watcher.EnableRaisingEvents = true;
