(3)TXT转为XML

<?xml version="1.0" encoding="utf-8"?>

<bocb2e>

  <head />

  <trans>

    <trn-b2e0035-rq>

      <b2e0035-rq>

        <ibknum>11111</ibknum>

        <actacn>111</actacn>

        <type>2001</type>

        <datescope>

          <from>20150320</from>

          <to>20150320</to>

        </datescope>

        <amountscope>

          <from>0</from>

          <to>100</to>

        </amountscope>

        <begnum />

        <recnum />

        <direction>0</direction>

      </b2e0035-rq>

    </trn-b2e0035-rq>

  </trans>

</bocb2e>

该段是一个XML代码，现在我们要做的是将以下的TXT文件转化为上述格式，TXT格式如下：

ibknum|actacnc|type |datescope_from|datescope_to|direction
1111 |111 |2002|20020214 |20020214 |0

首先，有两个路径，分别是读取路径和保存路径，downfolder和savefolder。我们的txt是保存在ftp服务器上的，这一点我们下一篇文章会讲述，怎么从ftp上下载一个文件。

现在我们直接从savefolder开始，也就是已经下载好的文件夹。

下面的方法现将txt转化为一个datatable，然后转换为list

        private DataTable B2eRqTxtToDt(string txtpath,string strErrMsg="",string encodingCode = "GB2312", string strSplit = "|")

        {if(txtpath.IndexOf("ftp")>=){

                //创建ftp请求信息

                var ftpRequest = new FtpClient(ftpUser, ftpPassword);

                string savePath = GetDataFileSavePath();

                ftpRequest.DownloadFile(savePath, txtpath, true);

            }

            //read first line

            StreamReader objReader = new StreamReader(savePath, Encoding.GetEncoding(encodingCode));

            string sLine = objReader.ReadLine();

            objReader.Close();

            //all column's header

            string[] ColumnHeaders = sLine.ToString().Trim().Split(strSplit).Select(q => q.Trim()).ToArray();

            // to datatable

            //直接取datatable

            DataTable dt = TxtService.TextFileLoader(savePath, "txt", ColumnHeaders, out strErrMsg, encodingCode, strSplit);

            return dt;

        }

        private List<RqList> B2eRqDtToLs(DataTable dt)

        {

            var date = DateTime.Now.AddDays(-).Date;

            List<RqList> rqlist = new List<RqList>();

            for (int i = ; i < dt.Rows.Count; i++)

            {

                RqList rqls = new RqList();

                b2e0035_rq b2erq = new b2e0035_rq();

                b2erq.ibknum = dt.Rows[i][].ToString();

                b2erq.actacn = dt.Rows[i][].ToString();

                b2erq.type = "";

                b2erq.datescope_from = date.Date;

                b2erq.datescope_to = date.Date;

                b2erq.amountscope_from = null;

                b2erq.amountscope_to = null;

                b2erq.begnum = null;

                b2erq.recnum = null;

                b2erq.direction = "";

                #region //这几句是读取txt文件中的.另外还有string转换为DateTime类型的。

                b2erq.type = dt.Rows[i][].ToString();

                b2erq.datescope_from = DateTime.Parse(dt.Rows[i][].ToString());

                #endregion

                rqls.head = null;

                rqls.b2e0035_rq = b2erq;

                rqlist.Add(rqls);

            }

                return rqlist;

        }

将txt转化为list之后，借助写XML方法可以将其写入XML中。

 public void WriteToXML(string ibknum,string actacn,string path)

        {

            //string path = @"C:\Users\zuomeiyan\XMLRequest.xml";

            XmlTextWriter xtw = new XmlTextWriter(path, UTF8Encoding.UTF8);

            var date = DateTime.Now.AddDays(-).Date;

            try

            {

                xtw.Formatting = Formatting.Indented;

                xtw.WriteStartDocument();

                xtw.WriteStartElement("bocb2e");

                ////head

                xtw.WriteStartElement("head");

                xtw.WriteEndElement();

                //交易数据块

                xtw.WriteStartElement("trans");

                xtw.WriteStartElement("trn-b2e0035-rq");

                xtw.WriteStartElement("b2e0035-rq");

                xtw.WriteElementString("ibknum", ibknum);

                xtw.WriteElementString("actacn", actacn);

                xtw.WriteElementString("type", "");

                xtw.WriteStartElement("datescope");

                xtw.WriteElementString("from", date.Date.ToString("yyyyMMdd"));

                xtw.WriteElementString("to", date.Date.ToString("yyyyMMdd"));

                xtw.WriteEndElement();

                xtw.WriteStartElement("amountscope");

                xtw.WriteElementString("from", null);

                xtw.WriteElementString("to", null);

                xtw.WriteEndElement();

                xtw.WriteElementString("begnum", null);

                xtw.WriteElementString("recnum", null);

                xtw.WriteElementString("direction", "");

                xtw.WriteEndElement();

                xtw.WriteEndElement();

                xtw.WriteEndElement();

                xtw.WriteEndElement();

                xtw.WriteEndDocument();

            }

            catch { }

            finally

            {

                xtw.Flush();

                xtw.Close();

                xtw.Dispose();

            }

        }

这样我们就完成了将一个TXT文件转化为XML格式。
