How do I get the XMLSerializer to add namespaces to attributes in nested objects?
提问by svinto
This is what I get:
这就是我得到的：
<ex:test soap:mustUnderstand="1" xmlns:ex="http://www.example.com/namespace">
<ex:A Type="lorem">ipsum</ex:A>
</ex:test>
This is what I want: (Note that the Type-attribute is prefixed with ex.)
这就是我想要的：（请注意，类型属性以 ex 为前缀。）
<ex:test soap:mustUnderstand="1" xmlns:ex="http://www.example.com/namespace">
<ex:A ex:Type="lorem">ipsum</ex:A>
</ex:test>
This is my code:
这是我的代码：
[XmlType(Namespace = "http://www.example.com/namespace")]
[XmlRoot("ex", Namespace = "http://www.example.com/namespace")]
public class TestSoapHeader : SoapHeader {
private TestSoapHeaderTypeValuePair _a;
public TestHeader() {
MustUnderstand = true;
}
[XmlNamespaceDeclarations]
public XmlSerializerNamespaces xmlsn {
get {
XmlSerializerNamespaces xsn = new XmlSerializerNamespaces();
xsn.Add("ex", "http://www.example.com/namespace");
return xsn;
}
set { }
}
public TestSoapHeaderTypeValuePair A {
get { return _a; }
set { _a = value; }
}
}
[XmlType(Namespace = "http://www.example.com/namespace")]
public class TestSoapHeaderTypeValuePair {
private string _type;
private string _value;
[XmlNamespaceDeclarations]
public XmlSerializerNamespaces xmlsn
{
get
{
XmlSerializerNamespaces xsn = new XmlSerializerNamespaces();
xsn.Add("ex", "http://www.example.com/namespace");
return xsn;
}
set { }
}
public TestSoapHeaderTypeValuePair(string type, string value) {
Type = type;
Value = value;
}
public TestSoapHeaderTypeValuePair() {}
[System.Xml.Serialization.XmlAttributeAttribute("type", Namespace = "http://www.example.com/namespace")]
public string Type {
get { return _type; }
set { _type = value; }
}
[System.Xml.Serialization.XmlText()]
public string Value {
get { return _value; }
set { _value = value; }
}
}

IXmlSerializablemaybe?
IXmlSerializable也许？
Note I also added (to A):
注意我还添加了（到A）：
[XmlElement("A", Namespace = "http://www.example.com/namespace")]
public TestSoapHeaderTypeValuePair A {...}
here's the code:
这是代码：
public class TestSoapHeaderTypeValuePair : IXmlSerializable
{
private string _type;
private string _value;
public TestSoapHeaderTypeValuePair(string type, string value)
{
Type = type;
Value = value;
}
public TestSoapHeaderTypeValuePair() { }
public string Type
{
get { return _type; }
set { _type = value; }
}
public string Value
{
get { return _value; }
set { _value = value; }
}
#region IXmlSerializable Members
System.Xml.Schema.XmlSchema IXmlSerializable.GetSchema()
{
return null;
}
void IXmlSerializable.ReadXml(System.Xml.XmlReader reader)
{
throw new NotImplementedException();
}
void IXmlSerializable.WriteXml(System.Xml.XmlWriter writer)
{
writer.WriteAttributeString("ex", "type", "http://www.example.com/namespace", Type);
writer.WriteString(Value);
}
#endregion
}

e.g. xsd.exe complex.xml xsd.exe gen1.xsd gen2.xsd /c
例如 xsd.exe complex.xml xsd.exe gen1.xsd gen2.xsd /c
no need to touch xsd generated files (except to replace [][] -> [])
无需触摸 xsd 生成的文件（除了替换 [][] -> []）
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("dfs", "http://schemas.microsoft.com/office/infopath/2003/dataFormSolution");
ns.Add("d", "http://schemas.microsoft.com/office/infopath/2009/WSSList/dataFields");
ns.Add("pc", "http://schemas.microsoft.com/office/infopath/2007/PartnerControls");
XmlSerializer serializer = new XmlSerializer(typeof(myFields));
StringBuilder sb = new StringBuilder();
using (StringWriter writer = new StringWriter(sb))
{
serializer.Serialize(writer, myFields, ns);
return sb.ToString();
}
