我正在尝试从XML文档中提取数据，并根据C＃中的时间汇总数据。
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>"
请忽略引号和'+'：这是因为我试图创建虚假XML数据并将其作为字符串传递给C＃中的列表。
文件2：
"<HourlyTotals>" +
"<Data>" +
"<Time>08:00</Time>" +
"<NetSales>100.25</NetSales>" +
"<NetReturns>10.25</NetReturns>" +
"<NetIncome>176.00</NetIncome>" +
"<CustomerCount>10</CustomerCount>" +
"<PercentOfIncome>1</PercentOfIncome>" +
"</Data>" +
"<Data>" +
"<Time>08:15</Time>" +
"<NetSales>120.00</NetSales>" +
"<NetReturns>11.00</NetReturns>" +
"<NetIncome>54.00</NetIncome>" +
"<CustomerCount>5</CustomerCount>" +
"<PercentOfIncome>2.3</PercentOfIncome>" +
"</Data>" +
"<Data>" +
"<Time>08:30</Time>" +
"<NetSales>160.11</NetSales>" +
"<NetReturns>17.25</NetReturns>" +
"<NetIncome>34.00</NetIncome>" +
"<CustomerCount>4</CustomerCount>" +
"<PercentOfIncome>3.2</PercentOfIncome>" +
"</Data>" +
"<Data>" +
"<Time>09:15</Time>" +
"<NetSales>100.25</NetSales>" +
"<NetReturns>10.25</NetReturns>" +
"<NetIncome>176.00</NetIncome>" +
"<CustomerCount>10</CustomerCount>" +
"<PercentOfIncome>1</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>"
文件3：
"<HourlyTotals>" +
"<Data>" +
"<Time>08:00</Time>" +
"<NetSales>22.25</NetSales>" +
"<NetReturns>21.25</NetReturns>" +
"<NetIncome>122.00</NetIncome>" +
"<CustomerCount>3</CustomerCount>" +
"<PercentOfIncome>6</PercentOfIncome>" +
"</Data>" +
"<Data>" +
"<Time>08:15</Time>" +
"<NetSales>174.00</NetSales>" +
"<NetReturns>16.00</NetReturns>" +
"<NetIncome>68.00</NetIncome>" +
"<CustomerCount>2</CustomerCount>" +
"<PercentOfIncome>0.2</PercentOfIncome>" +
"</Data>" +
"<Data>" +
"<Time>08:30</Time>" +
"<NetSales>99.00</NetSales>" +
"<NetReturns>88.00</NetReturns>" +
"<NetIncome>69.00</NetIncome>" +
"<CustomerCount>6</CustomerCount>" +
"<PercentOfIncome>9</PercentOfIncome>" +
"</Data>" +
"<Data>" +
"<Time>09:30</Time>" +
"<NetSales>100.25</NetSales>" +
"<NetReturns>10.25</NetReturns>" +
"<NetIncome>176.00</NetIncome>" +
"<CustomerCount>10</CustomerCount>" +
"<PercentOfIncome>1</PercentOfIncome>" +
"</Data>" +
"</HourlyTotals>"
我希望按时间汇总NetSales，NetReturns，NetIncome，CustomerCount和PercentOfIncome值。例如，时间8:00应该具有值 322.75 （200.25 + 100.25 + 22.25）作为NetSales值等等。
时间节点值的范围为8:00到23:45。我试图找出一种有效的方法来提取所有时间间隔并根据它们汇总值。
到目前为止，我已编写代码从XML中提取单个节点的数据：
foreach (var selector in fakeXML)
{
XDocument doc = XDocument.Parse(selector);
var data = doc.Descendants("Data");
var result1 = from q in data
select new
{
Time = q.Element("Time").Value,
NetSales = q.Element("NetSales").Value,
NetReturns = q.Element("NetReturns").Value,
NetIncome = q.Element("NetIncome").Value,
CustCount = q.Element("CustomerCount").Value,
PercentOfIncome = q.Element("PercentOfIncome").Value
}
}
fakeXML是一个字符串列表，其中包含单个XML文档作为字符串。
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。任何关于如何进行的线索都会非常棒！
提前致谢。

获得所有数据后。按Time分组，然后Sum将每组中的值分组。
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),
});
摘要集合中的每个项目都有按时间计算的总计。
