如何在C#中使用XML(XML来自Web服务)创建Crystal报表

我想知道如何从XML创建一个水晶报表(XML来自Web服务),我在一些教程中读到它需要找到文件并拖动报表中的字段,但是如何从一个XML中获取XML网络服务？

以下是我如何从Web服务获取XML的代码

  var doc = XDocument.Parse(trx.GetCardTrx("xxxxx", "xxxx", "xxx", "", dateTimePicker1.Text, dateTimePicker2.Text, "", "", "", "", "", "", "", "", "", "", "", "FALSE", "", "", "", "", "", "", "", "", "", "", ""));
MessageBox.Show(doc.ToString());

所以这段代码返回这种值(来自MessageBox.Show(doc.ToString())

这是应该在报告中的选定值的代码

var summary = from r in doc.Descendants("TrxDetailCard") 
                      select new 
                      {
                          Account_Type = r.Element("Account_Type_CH").Value,
                          Captured = r.Element("Captured").Value,
                          Trans_Type_ID = r.Element("Trans_Type_ID").Value,
                          Acct_Num_CH = r.Element("Acct_Num_CH").Value,
                          Tip_Amt_MN = r.Element("Tip_Amt_MN").Value,
                          Total_Amt_MN = r.Element("Total_Amt_MN").Value,
                          Date_DT = r.Element("Date_DT").Value,
                      };

我想要发生的是使用Crystal Reports创建一个包含此值的报表,而不是所有值.仅选定值.我怎么可能这样做？任何想法都将是一个很大的帮助谢谢你：D

解决方法:

这尚未经过测试,但您可以尝试以下内容

using System.Xml;
using System.Xml.Linq;

var doc = XDocument.Parse(trx.GetCardTrx("xxxxx", "xxxx", "xxx", "", dateTimePicker1.Text, dateTimePicker2.Text, "", "", "", "", "", "", "", "", "", "", "", "FALSE", "", "", "", "", "", "", "", "", "", "", ""));

  var data = new DataSet();
  var context = new XmlParserContext(null, new XmlNamespaceManager(new NaMetable()), null, XmlSpace.None);
  var reader = doc
  data.readxml(reader);

  var report = new ReportDocument();

  report.SetDataSource(data);
  this.crystalReportViewer1.ReportSource.ReportSource = report;

理论上的理念应该有效,但你可以从这个链接中引用类似的东西
