使用XMLReader在c＃中解析多个类似节点的XML

Question

我收到肥皂服务的回复。它看起来像：

<ArrayOfPaymentHistory_ST xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">
  <PaymentHistory_ST>
    <tTRANSDATE>2015-01-05T08:58:17</tTRANSDATE>
    <tPAIDTO>2015-02-01T00:00:00</tPAIDTO>
    <dAMOUNT>110</dAMOUNT>
    <dBALANCE>0</dBALANCE>
    <TRANSKIND>Auto CC Payment</TRANSKIND>
    <csUnit>Lee</csUnit>
  </PaymentHistory_ST>
  <PaymentHistory_ST>
    <tTRANSDATE>2015-01-01T08:58:17</tTRANSDATE>
    <tPAIDTO>2015-01-01T00:00:00</tPAIDTO>
    <dAMOUNT>-110</dAMOUNT>
    <dBALANCE>110</dBALANCE>
    <TRANSKIND>Rent Posted</TRANSKIND>
    <csUnit>Lee</csUnit>
  </PaymentHistory_ST>
</ArrayOfPaymentHistory_ST>

我已经定义了这样的模型：

public class payment_history
{
    public DateTime tTRANSDATE { get; set; }
    public DateTime tPAIDTO { get; set; }
    public double dAMOUNT { get; set; }
    public double dBALANCE { get; set; }
    public string TRANSKIND { get; set; }
}

我正在尝试解析此XML响应并创建payment_history类型的对象列表。 然后，我将在标记上发送此对象并显示在表格中。 我发现了许多使用XMLReader进行XML解析的帖子。我仍然无法找到一个可以优雅地做到这一点的好解决方案。

这是我的c＃代码。

List<payment_history> ph = new List<payment_history>();
payment_history p = new payment_history();

            using (WebResponse response = request.GetResponse())
            {
                using (StreamReader rd = new StreamReader(response.GetResponseStream()))
                {
                    string soapResult = rd.ReadToEnd();

                    using (XmlReader reader = XmlReader.Create(new StringReader(soapResult)))
                    {
                        #region parseXML
                        while (reader.Read())
                        {
                            foreach (var el in reader.ReadOuterXml())
                            {
                                if (reader.IsStartElement())
                                {
                                    //return only when you have START tag
                                    switch (reader.Name.ToString())
                                    {
                                        case "tTRANSDATE":
                                            p.tTRANSDATE = Convert.ToDateTime(reader.ReadString());
                                            break;

                                        case "tPAIDTO":
                                            p.tPAIDTO = Convert.ToDateTime(reader.ReadString());
                                            break;

                                        case "dAMOUNT":
                                            p.dAMOUNT = Convert.ToDouble(reader.ReadString());
                                            break;

                                        case "dBALANCE":
                                            p.dBALANCE = Convert.ToDouble(reader.ReadString());
                                            break;
                                        case "TRANSKIND":
                                            p.TRANSKIND = reader.ReadString();
                                            break;
                                    }
                                    ph.Add(p);
                                }
                            }
                        }
                        #endregion
                    }
                }
            }
            return ph;

有人可以指导这项工作吗？我是c＃的新手。任何形式的帮助将不胜感激。

我尝试过遵循LINQ2XML。但是没有任何回报!!

ph = XDocument.Parse(soapResult)
                 .Descendants("PaymentHistory_ST")
                 .Select(g => new payment_history
                 {
                     tTRANSDATE = (DateTime)g.Element("tTRANSDATE"),
                     tPAIDTO = (DateTime)g.Element("tPAIDTO"),
                     dAMOUNT = (double)g.Element("dAMOUNT"),
                     dBALANCE = (double)g.Element("dBALANCE"),
                     TRANSKIND = (string)g.Element("TRANSKIND")
                 }).ToList();

Answer 1

使用

XDocument doc = XDocument.Load(response.GetResponseStream());
XNamespace df = "http://tempuri.org/";

List<payment_history> ph = doc.Descendants(df + "PaymentHistory_ST")
                 .Select(g => new payment_history
                 {
                     tTRANSDATE = (DateTime)g.Element(df + "tTRANSDATE"),
                     tPAIDTO = (DateTime)g.Element(df + "tPAIDTO"),
                     dAMOUNT = (double)g.Element(df + "dAMOUNT"),
                     dBALANCE = (double)g.Element(df + "dBALANCE"),
                     TRANSKIND = (string)g.Element(df + "TRANSKIND")
                 }).ToList();
