在C＃中填充Web服务上的任何元素 [英] Populating ANY elements on a web service in C#
问题描述
有人可以给我指出一个C＃示例，在该示例中，他们填充一个请求并接收对该Web服务的响应，该Web服务中的模式主要实现为ANY元素？
Can someone point me to a C# example where they populate a request and receive the response for a web service where the schema is mostly implemented as ANY elements?
我已将Web服务引用添加到我的项目中。 Web服务的WSDL /模式将服务请求和响应的大部分内容作为 ANY元素。我知道基于Java实现此Web服务请求的客户端的基础架构。在此先感谢您的帮助。
I have added a web service reference to my project. The WSDL/schema for the web service has most of the body of the service request and response as an 'ANY' element. I know the underlying schema based on implementing a client to this web service request in Java. Thanks in advance for help.
ServiceGenericRequest_Type requestBody = <init>
GenericRequestData_Type genericRequest = <init>;
// here is where the ANY element starts
genericRequest.Any = new System.Xml.XmlElement[1];
// receive error that I can not create abstract type
System.Xml.XmlNode inqNode = new System.Xml.XmlNode();
genericRequest.Any[0].AppendChild(inqNode);`
推荐答案
您的问题相当笼统，因此我将其范围缩小到以下情况：您的类型为 [XmlAnyElement] 成员如下：
Your question is fairly general so I'm going to narrow it down a bit to the following situation: you have a type with an [XmlAnyElement] member like so:
public class GenericRequestData_Type
{
private System.Xml.XmlElement[] anyField;
[System.Xml.Serialization.XmlAnyElementAttribute()]
public System.Xml.XmlElement[] Any
{
get
{
return this.anyField;
}
set
{
this.anyField = value;
}
}
}
您想初始化任何字段到以下XML：
And you would like to initialize the Any field to the following XML:
<Contacts>
<Contact>
<Name>Patrick Hines</Name>
<Phone>206-555-0144</Phone>
<Address>
<Street1>123 Main St</Street1>
<City>Mercer Island</City>
<State>WA</State>
<Postal>68042</Postal>
</Address>
</Contact>
</Contacts>
这怎么办？
有几种选择，所以我将其分解为几个不同的答案。
There are several options, so I'll break it down into a few different answers.
首先，您可以使用代码生成工具（例如 http://xmltocsharp.azurewebsites.net）设计与所需XML相对应的c＃类。 / 或Visual Studio的将XML粘贴为类。然后，您可以使用 XmlSerializer 与 XmlDocument.CreateNavigator（）。AppendChild（） 。
Firstly, you could design c# classes corresponding to your desired XML using a code-generation tool such as http://xmltocsharp.azurewebsites.net/ or Visual Studio's Paste XML as Classes. Then you can serialize those classes directly to an XmlNode hierarchy using XmlSerializer combined with XmlDocument.CreateNavigator().AppendChild().
首先，介绍以下扩展方法：
First, introduce the following extension methods:
public static class XmlNodeExtensions
{
public static XmlDocument AsXmlDocument<T>(this T o, XmlSerializerNamespaces ns = null, XmlSerializer serializer = null)
{
XmlDocument doc = new XmlDocument();
using (XmlWriter writer = doc.CreateNavigator().AppendChild())
new XmlSerializer(o.GetType()).Serialize(writer, o, ns ?? NoStandardXmlNamespaces());
return doc;
}
public static XmlElement AsXmlElement<T>(this T o, XmlSerializerNamespaces ns = null, XmlSerializer serializer = null)
{
return o.AsXmlDocument(ns, serializer).DocumentElement;
}
public static T Deserialize<T>(this XmlElement element, XmlSerializer serializer = null)
{
using (var reader = new ProperXmlNodeReader(element))
return (T)(serializer ?? new XmlSerializer(typeof(T))).Deserialize(reader);
}
/// <summary>
/// Return an XmlSerializerNamespaces that disables the default xmlns:xsi and xmlns:xsd lines.
/// </summary>
/// <returns></returns>
public static XmlSerializerNamespaces NoStandardXmlNamespaces()
{
var ns = new XmlSerializerNamespaces();
ns.Add("", ""); // Disable the xmlns:xsi and xmlns:xsd lines.
return ns;
}
}
public class ProperXmlNodeReader : XmlNodeReader
{
// Bug fix from this answer https://stackoverflow.com/a/30115691/3744182
// To http://stackoverflow.com/questions/30102275/deserialize-object-property-with-stringreader-vs-xmlnodereader
// By https://stackoverflow.com/users/8799/nathan-baulch
public ProperXmlNodeReader(XmlNode node) : base(node) { }
public override string LookupNamespace(string prefix)
{
return NameTable.Add(base.LookupNamespace(prefix));
}
}
接下来，定义与您的<$ c $相对应的类型c>< Contacts> 层次结构：
Next, define types corresponding to your <Contacts> hierarchy:
[XmlRoot(ElementName = "Address")]
public class Address
{
[XmlElement(ElementName = "Street1")]
public string Street1 { get; set; }
[XmlElement(ElementName = "City")]
public string City { get; set; }
[XmlElement(ElementName = "State")]
public string State { get; set; }
[XmlElement(ElementName = "Postal")]
public string Postal { get; set; }
}
[XmlRoot(ElementName = "Contact")]
public class Contact
{
[XmlElement(ElementName = "Name")]
public string Name { get; set; }
[XmlElement(ElementName = "Phone")]
public string Phone { get; set; }
[XmlElement(ElementName = "Address")]
public Address Address { get; set; }
}
[XmlRoot(ElementName = "Contacts")]
public class Contacts
{
[XmlElement(ElementName = "Contact")]
public Contact Contact { get; set; }
}
[XmlRoot("GenericRequestData_Type")]
public class Person
{
public string Name { get; set; }
public DateTime BirthDate { get; set; }
[XmlArray("Emails")]
[XmlArrayItem("Email")]
public List<string> Emails { get; set; }
[XmlArray("Issues")]
[XmlArrayItem("Id")]
public List<long> IssueIds { get; set; }
}
最后，初始化 GenericRequestData_Type 如下：
var genericRequest = new GenericRequestData_Type();
var contacts = new Contacts
{
Contact = new Contact
{
Name = "Patrick Hines",
Phone = "206-555-0144",
Address = new Address
{
Street1 = "123 Main St",
City = "Mercer Island",
State = "WA",
Postal = "68042",
},
}
};
genericRequest.Any = new[] { contacts.AsXmlElement() };
