有人能指出我的C#示例,他们填充请求并接收Web服务的响应,其中架构主要是作为任何元素实现的吗?
我已经为我的项目添加了一个Web服务引用。 Web服务的WSDL /模式将服务请求和响应的大部分内容作为“任何”服务。元件。我知道基于在Java中使用此Web服务请求实现客户端的底层模式。在此先感谢您的帮助。
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);`

你的问题相当普遍,所以我要稍微缩小一下以下情况:你有一个类似[XmlAnyElement]
成员的类型:
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;
}
}
}
您希望将Any
字段初始化为以下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>
如何做到这一点?
有几个选项,所以我会将其分解为几个不同的答案。
首先,您可以使用代码生成工具(如http://xmltocsharp.azurewebsites.net/或Visual Studio的Paste XML as Classes)设计与所需XML相对应的c#类。然后,您可以使用XmlSerializer
结合XmlDocument.CreateNavigator().AppendChild()
将这些类直接序列化到XmlNode
层次结构。
首先,介绍以下扩展方法:
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 http://stackoverflow.com/questions/30102275/deserialize-object-property-with-stringreader-vs-xmlnodereader
public ProperXmlNodeReader(XmlNode node)
: base(node)
{
}
public override string LookupNamespace(string prefix)
{
return NameTable.Add(base.LookupNamespace(prefix));
}
}
接下来,定义与<Contacts>
层次结构相对应的类型:
[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,按如下方式初始化GenericRequestData_Type
:
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() };

XmlNode
是一种抽象基类型。您可以按照XmlElement
中的说明创建具体的Create New Nodes in the DOM对象并添加到Any
数组中:
XmlDocument
。虽然文档未在XmlElement [] Any
数组中明确显示,但随后需要创建元素。XmlDocument.CreateElement()
XmlNode.AppendChild
XmlElement.InnerText
设置文本值。因此以下内容将起作用:
var dom = new XmlDocument();
var contacts = dom.CreateElement("Contacts");
dom.AppendChild(contacts);
var contact = dom.CreateElement("Contact");
contacts.AppendChild(contact);
var name = dom.CreateElement("Name");
contact.AppendChild(name);
name.InnerText = "Patrick Hines";
var phone = dom.CreateElement("Phone");
contact.AppendChild(phone);
phone.InnerText = "206-555-0144";
var address = dom.CreateElement("Address");
contact.AppendChild(address);
var street1 = dom.CreateElement("Street1");
address.AppendChild(street1);
street1.InnerText = "123 Main St";
var city = dom.CreateElement("City");
address.AppendChild(city);
city.InnerText = "Mercer Island";
var state = dom.CreateElement("State");
address.AppendChild(state);
state.InnerText = "WA";
var postal = dom.CreateElement("Postal");
address.AppendChild(postal);
postal.InnerText = "68042";
var genericRequest = new GenericRequestData_Type();
genericRequest.Any = new[] { dom.DocumentElement };

XmlNode
是旧XML Document Object Model中的一种类型,可以追溯到c#1.1。它已被更容易使用的LINQ to XML对象模型所取代。不为人所知的是[XmlAnyAttribute]
实际上支持这个API。因此,在您的GenericRequestData_Type
类型中,您可以手动将Any
属性更改为System.Xml.Linq.XElement[]
类型:
public class GenericRequestData_Type
{
private System.Xml.Linq.XElement[] anyField;
[System.Xml.Serialization.XmlAnyElementAttribute()]
public System.Xml.Linq.XElement[] Any
{
get
{
return this.anyField;
}
set
{
this.anyField = value;
}
}
}
然后,您可以按照Creating XML Trees in C# (LINQ to XML):
中的说明轻松地按如下方式初始化数组// Taken from
// https://msdn.microsoft.com/en-us/library/mt693096.aspx
var contacts =
new XElement("Contacts",
new XElement("Contact",
new XElement("Name", "Patrick Hines"),
new XElement("Phone", "206-555-0144"),
new XElement("Address",
new XElement("Street1", "123 Main St"),
new XElement("City", "Mercer Island"),
new XElement("State", "WA"),
new XElement("Postal", "68042")
)
)
);
var genericRequest = new GenericRequestData_Type();
genericRequest.Any = new[] { contacts };
