Question

我正在使用c＃windows窗体处理文件监视器应用程序。要求是，我将有多个文件夹，当在这些文件夹中创建文件时，我需要跟踪它们并根据更改的文件运行集成包。以下是我的代码

private void btnStart_Click(object sender, EventArgs e) //start
        {
            Watching.Items.Clear();
            foreach (string sMonitorFolder in Global.DirectoryToWatch())
            {
                if (!(Directory.Exists(sMonitorFolder)))
                {
                    MessageBox.Show("Directory does not exist", "Exit", MessageBoxButtons.OK);
                    return;
                }

                _watcher.Path = sMonitorFolder;
                _watcher.Filter = comboBox1.Text;

                Watching.Items.Add("Watching" + sMonitorFolder +" ...");
                _watcher.IncludeSubdirectories = true;

                _watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.CreationTime | NotifyFilters.FileName |
                                        NotifyFilters.DirectoryName | NotifyFilters.LastWrite | NotifyFilters.Size;

                _watcher.Created += new FileSystemEventHandler(OnChanged);
                _watcher.EnableRaisingEvents = true;
            }

            btnStart.Enabled = false;
            btnStop.Enabled = true;
            textBox1.Enabled = false;
            comboBox1.Enabled = false;
            btnWrite.Enabled = true;
        }

onChanged事件处理程序

private void OnChanged(object sender, FileSystemEventArgs e)
    {
        // Add event details in listbox.
        this.Invoke((MethodInvoker) (() =>
            Watching.Items.Add($"{e.FullPath}|{e.ChangeType}|{e.Name}|{DateTime.Now}")));
    }

我正在存储需要在xml文件中观看的所有文件夹。我有一个全局的cs，我正在阅读这个xml文件并获取我需要观察的各种目录。

xml文件的结构

<?xml version="1.0" encoding="utf-8" ?> 
<root>
  <FolderToWatch>
    <value>D:/FolderService/Test</value>
    <value>D:/FolderService/Data</value>
  </FolderToWatch>
  <FileExtension>
    <value>.txt</value>
  </FileExtension>
  <LogFilePath>
    <value>D:/FileWatcherLog/</value>
  </LogFilePath>

</root>

以下是我的global.cs

static class Global
{
    static string       output;
    static List<string> filter;
    static XmlDocument  doc;

    /// <summary>
    ///
    /// </summary>
    static Global()
    {
        doc = new XmlDocument();
        doc.Load(Path.Combine(Directory.GetParent(Assembly.GetExecutingAssembly().Location).FullName, "setting.xml"));
        //doc.Load(Path.Combine(System.Reflection.Assembly.GetExecutingAssembly().Location, "setting.xml"));

        output = doc.SelectSingleNode("/root/LogFilePath/value").InnerText;
        filter = new List<string>();
        XmlNodeList exNodeList = doc.SelectNodes("/root/FileExtension/value");
        foreach (XmlNode nd in exNodeList)
            filter.Add(nd.InnerText);
    }
    /// <summary>
    /// Log : methods for performing the log write
    /// </summary>
    /// <param name="Message"></param>
    public static void WriteLog(string Message)
    {
        DateTime dateTime = System.DateTime.UtcNow.AddMinutes(330);
        if (!Directory.Exists(output))
            Directory.CreateDirectory(output);

        string logfileName = dateTime.ToString("dd_MMM_yy") + "_" + ".txt";
        StreamWriter streamwriter = new StreamWriter(output + logfileName, true);
        streamwriter.WriteLine(DateTime.Now + ": " + Message);
        streamwriter.Close();
        streamwriter.Dispose();

    }
    /// <summary>
    /// DirectoryArray : List of all the directory that required to be watched.
    /// </summary>
    /// <returns>Array</returns>
    public static Boolean GetFileExtention(string filePath)
    {
        string fileEX = Path.GetExtension(filePath);
        return filter.Contains(fileEX);
    }
    /// <summary>
    ///
    /// </summary>
    /// <returns></returns>
    public static List<string> DirectoryToWatch()
    {
        List<string> liFolderToWatch = new List<string>();
        XmlNodeList ndWatchFolders = doc.SelectNodes("/root/FolderToWatch/value");
        foreach (XmlNode nd in ndWatchFolders)
            liFolderToWatch.Add(nd.InnerText);

        return liFolderToWatch;
    }
}

代码仅适用于一个目录，而不适用于所有目录。它适用于在xml文件中指定的最后一个目录，并且先前的目录将被忽略。我需要为我在xml文件中的foldertowatch节点中指定的每个目录创建多个观察者。任何人都可以帮我解决这个问题吗？
