FileWatcher事件后刷新页面

Question

我的asp net mvc应用程序中有FileSystemWatcher。它会在更改后检测.txt文件。我应该在视图页面上显示这些更改。但我无法理解它是如何做到的。因为我如何从FileSystemWatcher调用页面刷新？或者我必须在客户端编写setTimeOut js函数？这是代码：

public class FileWatcher
{
    //private int readLinesCount = 0;
    private string watchedPath;

    public FileWatcher(string watchedPath)
    {
        this.watchedPath = watchedPath;
        InitFileSystemWatcher();
    }

    private void InitFileSystemWatcher()
    {
        FileSystemWatcher oFileWatcher = new FileSystemWatcher();

        //Set the path that you want to monitor.
        oFileWatcher.Path = watchedPath;

        //Set the Filter Expression.
        oFileWatcher.Filter = "*.txt";

        oFileWatcher.Changed += new FileSystemEventHandler(FileSystemWatcherUpdated);

        oFileWatcher.Error += Watcher_Error;

        oFileWatcher.EnableRaisingEvents = true;
    }

    private void Watcher_Error(object sender, ErrorEventArgs e)
    {
        // Watcher crashed. Re-init.
        InitFileSystemWatcher();
    }

    void FileSystemWatcherUpdated(object sender, FileSystemEventArgs e)
    {
        //A file has been changed in the monitor directory.
        try
        {
            RecordEntry(e.Name);
        }
        catch (Exception)
        {
            InitFileSystemWatcher();
        }
    }

    private void RecordEntry(string fileName)
    {
        BLogic bll = new BLogic();
        bll.AddParamsByFileWatcher(fileName);
    }
}

这是一种BLogic的方法：

public void AddParamsByFileWatcher(string fileName)
{
    if (fileName != null)
    {
        HomeController controller = new HomeController();
        controller.Server.TransferRequest("/Home/Monitoring", false);
    }
}
