C# 用C语言从XML文档中提取和汇总数据#

我试图从XML文档中提取数据，并在C#中根据时间汇总数据

例如，我有以下XML文档：

文件1：

                "<HourlyTotals>" +
                "<Data>" +
                "<Time>08:00</Time>" +
                "<NetSales>200.25</NetSales>" +
                "<NetReturns>15.25</NetReturns>" +
                "<NetIncome>185.00</NetIncome>" +
                "<CustomerCount>15</CustomerCount>" +
                "<PercentOfIncome>3</PercentOfIncome>" +
                "</Data>" +
                "<Data>" +
                "<Time>08:15</Time>" +
                "<NetSales>100.25</NetSales>" +
                "<NetReturns>15.25</NetReturns>" +
                "<NetIncome>85.00</NetIncome>" +
                "<CustomerCount>2</CustomerCount>" +
                "<PercentOfIncome>1.5</PercentOfIncome>" +
                "</Data>" +
                 "<Data>" +
                "<Time>08:30</Time>" +
                "<NetSales>100.25</NetSales>" +
                "<NetReturns>15.25</NetReturns>" +
                "<NetIncome>85.00</NetIncome>" +
                "<CustomerCount>2</CustomerCount>" +
                "<PercentOfIncome>1.5</PercentOfIncome>" +
                "</Data>" +
                "<Data>" +
                "<Time>10:00</Time>" +
                "<NetSales>100.25</NetSales>" +
                "<NetReturns>10.25</NetReturns>" +
                "<NetIncome>176.00</NetIncome>" +
                "<CustomerCount>10</CustomerCount>" +
                "<PercentOfIncome>1</PercentOfIncome>" +
                "</Data>" +
                "</HourlyTotals>"

fakeXML是字符串列表，其中包含作为字符串的各个XML文档

这段代码只允许我从XML文档中提取单个节点

我无法根据时间节点的值找出一种有效的方法来汇总它。任何关于如何进行的线索都将非常棒

提前感谢。

在您获得所有数据后。按

Time

对它们进行分组，然后将每组中的值相加

var data = fakeXML.SelectMany(selector => {
    XDocument doc = XDocument.Parse(selector);
    return from q in doc.Descendants("Data")
           select new {
               Time = q.Element("Time").Value,
               NetSales = (decimal)q.Element("NetSales"),
               NetReturns = (decimal)q.Element("NetReturns"),
               NetIncome = (decimal)q.Element("NetIncome"),
               CustCount = (int)q.Element("CustomerCount"),
               PercentOfIncome = (double)q.Element("PercentOfIncome")
           };
});

var summary = data.GroupBy(d => d.Time)
    .Select(g => new {
        Time = g.Key,
        NetSales = g.Sum(d => d.NetSales),
        NetReturns = g.Sum(d => d.NetReturns),
        NetIncome = g.Sum(d => d.NetIncome),
        CustCount = g.Sum(d => d.CustCount),
    });

汇总集合中的每个项目都会按时间进行汇总。

在获得所有数据后。按时间和每组中值的总和分组。我不会使用

decimal.Parse（）

、

int.Parse（）

或

double.Parse（）

，因为它们是特定于区域设置的。相反，请使用已经提供的API，例如对于

decimal

或仅使用小数：

NetSales=（decimal）q.Element（“NetSales”），

@dbc fixed。再次感谢你的建议。
