Вы можете делать то, что хотите, с помощью переопределений атрибутов XML.По сути, вы можете применять атрибуты XML Serialization к сериализатору во время выполнения.
См. Статью MSDN
Ниже приведен пример кода для использования переопределений атрибутов XML при сериализации XML.
public class DTO
{
[XmlIgnore]
public string additionalInformation;
[XmlElement(Order=1)]
public DateTime stamp;
[XmlElement(Order=2)]
public string name;
[XmlElement(Order=3)]
public double value;
[XmlElement(Order=4)]
public int index;
}
public class OverridesDemo
{
public void Run()
{
DTO dto = new DTO {
additionalInformation = "This information will be serialized separately",
stamp = DateTime.UtcNow,
name = "Marley",
value = 72.34,
index = 7
};
// this will allow us to omit the xmlns:xsi namespace
var ns = new XmlSerializerNamespaces();
ns.Add( "", "" );
XmlSerializer s1 = new XmlSerializer(typeof(DTO));
var builder = new System.Text.StringBuilder();
var settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent= true };
Console.WriteLine("\nSerialize using the in-line (compile-time) attributes: ");
using ( XmlWriter writer = XmlWriter.Create(builder, settings))
{
s1.Serialize(writer, dto, ns);
}
Console.WriteLine("{0}",builder.ToString());
Console.WriteLine("\n");
// use a default namespace
ns = new XmlSerializerNamespaces();
string myns = "urn:www.example.org";
ns.Add( "", myns );
XmlAttributeOverrides overrides = new XmlAttributeOverrides();
XmlAttributes attrs = new XmlAttributes();
// override the (implicit) XmlRoot attribute
XmlRootAttribute attr1 = new XmlRootAttribute
{
Namespace = myns,
ElementName = "DTO-Annotations",
};
attrs.XmlRoot = attr1;
overrides.Add(typeof(DTO), attrs);
// "un-ignore" the first property
// define an XmlElement attribute, for a type of "String", with no namespace
var a2 = new XmlElementAttribute(typeof(String)) { ElementName="note", Namespace = myns };
// add that XmlElement attribute to the 2nd bunch of attributes
attrs = new XmlAttributes();
attrs.XmlElements.Add(a2);
attrs.XmlIgnore = false;
// add that bunch of attributes to the container for the type, and
// specifically apply that bunch to the "Label" property on the type.
overrides.Add(typeof(DTO), "additionalInformation", attrs);
// ignore the other properties
// add the XmlIgnore attribute to the 2nd bunch of attributes
attrs = new XmlAttributes();
attrs.XmlIgnore = true;
// add that bunch of attributes to the container for the type, and
// specifically apply that bunch to the "Label" property on the type.
overrides.Add(typeof(DTO), "stamp", attrs);
overrides.Add(typeof(DTO), "name", attrs);
overrides.Add(typeof(DTO), "value", attrs);
overrides.Add(typeof(DTO), "index", attrs);
XmlSerializer s2 = new XmlSerializer(typeof(DTO), overrides);
Console.WriteLine("\nSerialize using the override attributes: ");
builder.Length = 0;
using ( XmlWriter writer = XmlWriter.Create(builder, settings))
{
s2.Serialize(writer, dto, ns);
}
Console.WriteLine("{0}",builder.ToString());
Console.WriteLine("\n");
}
Вы можете использовать переопределения для сериализации или десериализации.
