Question

当我在下面调用我的服务时，XML元素TruckName和Website为空？显然，元素在网页上的XML中是分开的（参见下面的xml）。我相信它与ArrayOf元素的关系是第一个？下面是我的控制台应用程序调用方法GetInfo（）的代码。我是否需要摆脱ArrayOfFoodTruck元素？如果是这样，最简单的方法。感谢所有提前..

- <ArrayOfFoodTruck xmlns="http://schemas.datacontract.org/2004/07/WCFServiceLibrary" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
- <FoodTruck>
 <Company i:nil="true" /> 
 <DayOfWeek i:nil="true" /> 
 <Location i:nil="true" /> 
 <TimeOfDay i:nil="true" /> 
 <TruckID>0</TruckID> 
 <TruckName>Truck 87</TruckName> 
 <Website>http://www.test.com</Website> 
 </FoodTruck>
- <FoodTruck>
<Company i:nil="true" /> 
<DayOfWeek i:nil="true" /> 
<Location i:nil="true" /> 
<TimeOfDay i:nil="true" /> 
<TruckID>0</TruckID> 
<TruckName>Bon Me</TruckName> 
<Website>http://www.test.com</Website> 
</FoodTruck>
</ArrayOfFoodTruck>

这是我的控制台应用程序的调用..

    static void GetInfo()
    {

        XElement rootXml = XElement.Load("http://localhost:5150/getnames");

         var FoodTruck = from C in rootXml.Elements()
         select new { TruckName = (string)C.Element("TruckName"), WebSite = (string)C.Element("Website") };
         foreach (var x in FoodTruck)

         Console.WriteLine("{0}\r\n{1}", x.TruckName, x.WebSite);
         Console.ReadKey();

    }

我猜你的命名空间有问题

XDocument xDoc = XDocument.Load(.....);
XNamespace ns = XNamespace.Get("http://schemas.datacontract.org/2004/07/WCFServiceLibrary");

var result = xDoc.Descendants(ns+"FoodTruck")
    .Select(n => new 
    { 
        TruckName=n.Element(ns+"TruckName").Value,
        WebSite = n.Element(ns+"Website").Value
    })
    .ToArray();

- 编辑 - 或

XmlSerializer ser = new XmlSerializer(typeof(FoodTruck[]), "http://schemas.datacontract.org/2004/07/WCFServiceLibrary");
var foodTrucks = (FoodTruck[])ser.Deserialize(new StringReader(xml));

public class FoodTruck
{
    public string Website;
    public string TruckName;
}

来自URI的REST WCF服务 - ArrayOf - Null元素
