XMLSerializer在n行（行）之后创建一个新文件

Question

我对XMLSerializer有问题：我有一个列表，并希望使用XMLSerializer将列表的内容写入XML。整个事情也很好。但是在n行之后，我想用XMLSerializer将数据写到新的XML中，但是数据总是写到现有的XML中。

我该如何解决，在n行之后创建一个新的XML文件？

要序列化的代码：

 private void SaveLogFile()
    {
        bf = new BaseFunctions();
        try
        {
            XmlSerializer seri = new XmlSerializer(typeof(List<LVProperties>));
            TextWriter wr = new StreamWriter(FilePath);

            seri.Serialize(wr, FileWatcher.Data);
            wr.Close();
        }
        catch (Exception ex)
        {
            bf.app_Errorhandler(ex);
            return;
        }
    }

用于收集数据以供Listview和数据表进行序列化的代码：

 public static List<LVProperties> Data = new List<LVProperties>();
    [STAThread]
    private void LogDataToLV()
    {
        ff = new FileFunctions();
        vlp = new LVProperties();
        bf = new BaseFunctions();

        bf.ReadAppInfos();

        _lvLogMe.Dispatcher.BeginInvoke(new Action(delegate ()
        {

            if (bf.osVersion.Major == 6 && bf.osVersion.Minor >= 2 || bf.osVersion.Major >= 10 && bf.osVersion.Minor >= 0)
            {
                LogMeUser = ff.getFileDetails(LogMePath, LogMeFile, FileFunctions.FileDetailInfo.Title); //Problem mit InvalidCastException!!
                LogMeSize = ff.getFileDetails(LogMePath, LogMeFile, FileFunctions.FileDetailInfo.Size);
            }
            else
            {
                LogMeUser = "not supported by OS";
                LogMeSize = "unknown";
            }
            _lvLogMe.Items.Add(new LVProperties { lv_LogMeDate = LogMeDate, lv_LogMeEvent = LogMeEvent, lv_LogMeFile = LogMeFile, lv_LogMePath = LogMePath, lv_LogMeUser = LogMeUser, lv_LogMeSize = LogMeSize });
            Data.Add(new LVProperties { lv_LogMeDate = LogMeDate, lv_LogMeEvent = LogMeEvent, lv_LogMeFile = LogMeFile, lv_LogMePath = LogMePath, lv_LogMeUser = LogMeUser, lv_LogMeSize = LogMeSize });
            _lvLogMe.SelectedIndex = _lvLogMe.Items.Count - 1;
            _tbLogCount.Text = _lvLogMe.Items.Count.ToString();
            if (VisualTreeHelper.GetChildrenCount(_lvLogMe) > 0)
            {
                Border border = (Border)VisualTreeHelper.GetChild(_lvLogMe, 0);
                ScrollViewer scrollViewer = (ScrollViewer)VisualTreeHelper.GetChild(border, 0);
                scrollViewer.ScrollToBottom();
            }
            _lvLogMe.UpdateLayout();
            _lvLogMe.DataContext = Data;
            LVRowCount = _lvLogMe.Items.Count;

            if (sXML.SaveLogAuto == "true")
            {
                if (LVRowCount == 10)
                {
                    SaveLogFile();
                }
            }

            if (_lvLogMe.Items.Count == 10)
            {
                _lvLogMe.Items.Clear();
                Data.Clear();
            }


        }));
    }

将newtonsoft.JSON包管理器与]一起使用>

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
 doc.Load(path); 
string json = JsonConvert.SerializeXmlNode(doc);
