我确定这很简单..
我把它作为一个字符串:
<OnTheRoadQuote xmlns:i="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://schemas.datacontract.org/2004/07/OTRAPI.Services.Models">
<BasicPrice>15595.8333</BasicPrice>
<CO2>93</CO2>
<Dealer>Audi</Dealer>
<DeliveryCost>524.9900</DeliveryCost>
<DiscountPrice>14348.166636</DiscountPrice>
<DiscountSum>1247.666664</DiscountSum>
<Discounts>
<Discount>
<DiscountApplication>Percentage</DiscountApplication>
<DiscountDescription>Dealer Discount on Vehicle and Options %</DiscountDescription>
<DiscountID>Discount1</DiscountID>
<DiscountType>VehicleAndOptions</DiscountType>
<DiscountValue>8</DiscountValue>
</Discount>
</Discounts>
<OTR>17902.7879632</OTR>
</OnTheRoadQuote>
如何读取OTR节点的值?
我有一个XmlReader,但不知道如何使用它。

使用XmlReader并修复根元素中的拼写错误(在第二个xmlns
之前缺少空格):
string xml = @"<OnTheRoadQuote xmlns:i=""http://www.w3.org/2001/XMLSchema-instance"" xmlns=""http://schemas.datacontract.org/2004/07/OTRAPI.Services.Models"">
<BasicPrice>15595.8333</BasicPrice>
<CO2>93</CO2>
<Dealer>Audi</Dealer>
<DeliveryCost>524.9900</DeliveryCost>
<DiscountPrice>14348.166636</DiscountPrice>
<DiscountSum>1247.666664</DiscountSum>
<Discounts>
<Discount>
<DiscountApplication>Percentage</DiscountApplication>
<DiscountDescription>Dealer Discount on Vehicle and Options %</DiscountDescription>
<DiscountID>Discount1</DiscountID>
<DiscountType>VehicleAndOptions</DiscountType>
<DiscountValue>8</DiscountValue>
</Discount>
</Discounts>
<OTR>17902.7879632</OTR>
</OnTheRoadQuote>";
string otrValue = "";
using (XmlReader reader = XmlReader.Create(new StringReader(xml))) // use a StringReader to load the XML string into an XmlReader
{
reader.ReadToFollowing("OTR"); // move the reader to OTR
reader.ReadStartElement(); // consume the start element
otrValue = reader.Value; // store the value in the otrValue string.
}
请记住,XmlReader仅仅向前,这意味着您无法通过XML数据向后导航,例如,Discounts
,一旦您&#39 ; ve将其推送到OTR
节点。如果你想这样做,你应该考虑使用XmlDocument
或(最好)XDocument
。但是,如果你需要做的只是获得OTR值,这应该是最有效(时间和空间)的方式。

使用较少的代码,您可以使用LINQ to XML并使用xml或文件加载XElement。还有其他选择。
XElement element = XElement.Load(....);
var node = element.Element("OTR");
