无法使用 DataContractSerializer 反序列化 xml



我无法将此XML反序列化为对象,我不知道这有什么问题:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<ProcessOneWayEvent xmlns="http://schemas.microsoft.com/sharepoint/remoteapp/">
<properties xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<CultureLCID>1033</CultureLCID>
</properties>
</ProcessOneWayEvent>
</s:Body>
</s:Envelope>

这里有一个现成的示例,有没有解决方法,因为我不能在请求中修改,所以我的模型有什么问题吗?有没有任何解决方案可以在不使用XmlSerializer的情况下反序列化XML

BodySPRemoteEventProperties需要在"http://schemas.microsoft.com/sharepoint/remoteapp/"命名空间中:

[DataContract(Name = "Body", Namespace = "http://schemas.microsoft.com/sharepoint/remoteapp/")]
public class Body
{
[DataMember(Name = "ProcessOneWayEvent")]
public ProcessOneWayEvent ProcessOneWayEvent;
}
[DataContract(Name = "properties", Namespace = "http://schemas.microsoft.com/sharepoint/remoteapp/")]
public class SPRemoteEventProperties
{
[DataMember(Name = "CultureLCID") ]
public int CultureLCID { get; set; }
}

DataContractAttribute.Namespace控制数据协定对象的数据成员元素序列化到的命名空间,以及当数据协定对象是根元素时根元素的命名空间。由于元素<ProcessOneWayEvent xmlns="http://schemas.microsoft.com/sharepoint/remoteapp/">声明了一个新的默认XML名称空间,因此元素本身及其子元素都在该名称空间中。因此,包含数据协定对象Body必须相应地设置其数据成员命名空间。至于<properties xmlns:i="http://www.w3.org/2001/XMLSchema-instance">i:名称空间不是默认名称空间,因此实际上没有元素被分配给这个名称空间,SPRemoteEventProperties类型也不应该将自己分配给它

我不明白为什么它不起作用,但一种选择是使用System.Xml.Serialization.XmlSerializer

首先,通过将XML复制到一个新类中来创建适当的Envelope类(编辑→选择性粘贴→将XML粘贴为类(

然后使用以下示例进行反序列化:

byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(request);
using (var stream = new MemoryStream(byteArray))
{
var serializer = new XmlSerializer(typeof(Envelope));
Envelope response = (Envelope)serializer.Deserialize(stream);
Console.WriteLine(JsonConvert.SerializeObject(response));
}

尝试以下操作:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = @"c:temptest.xml";
static void Main(string[] args)
{
string xml = File.ReadAllText(FILENAME);
StringReader sReader = new StringReader(xml);
XmlReader reader = XmlReader.Create(sReader);
XmlSerializer serializer = new XmlSerializer(typeof(Envelope));
Envelope envelope = (Envelope)serializer.Deserialize(reader);
}
}
[XmlRoot(ElementName = "Envelope", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public class Envelope
{
[XmlElement(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public Body Body { get; set; }
}
public class Body
{
[XmlElement(ElementName = "ProcessOneWayEvent", Namespace = "http://schemas.microsoft.com/sharepoint/remoteapp/")]
public ProcessOneWayEvent ProcessOneWayEvent { get; set; }
}
public class ProcessOneWayEvent
{
public Properties properties { get; set; } 
}
public class Properties
{
public string CultureLCID { get; set; }
}
}

使用Xml Linq

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = @"c:temptest.xml";
static void Main(string[] args)
{
string xml = File.ReadAllText(FILENAME);
XDocument doc = XDocument.Parse(xml);
string CultureLCID = (string)doc.Descendants().Where(x => x.Name.LocalName == "CultureLCID").FirstOrDefault();

}
}
}
