新增和查询数据 都是基于txt

 private void LoadData(string kind)
        {
            listView.Items.Clear();
            StreamReader streamReader = new StreamReader("Recorder.txt");
            try
            {
                while (!streamReader.EndOfStream)
                {
                    string nstr = streamReader.ReadLine();
                    string kstr = streamReader.ReadLine();
                    if((kind == "所有") || (kind == kstr))
                    {
                        ListViewItem item = listView.Items.Add(nstr);
                        item.SubItems.Add(kstr);
                        item.SubItems.Add(streamReader.ReadLine());
                        item.SubItems.Add(streamReader.ReadLine());
                        item.SubItems.Add(streamReader.ReadLine());
                    }
                    else
                    {
                        streamReader.ReadLine();
                        streamReader.ReadLine();
                        streamReader.ReadLine();
                    }


                }

            catch (Exception ex)
            {
                //
            }
            finally
            {
