How do I specify XML serialization attributes to support namespace prefixes during deserialization in .NET?

Question

I have a following XML:

<person xmlns:a="http://example.com" xmlns:b="http://sample.net">     <a:fName>John</a:fName>     <a:lName>Wayne</a:lName>     <b:age>37</b:age> </person> 

How do I define XML serialization attributes on a class to support described scenario?

Answer 1

You'll need to indicate which namespaces each field requires by using Namespace of XmlElement attribute. This will allow you to associate a field with a particular namespace, but you'll also need to expose a property on your class that returns type XmlNamespaceDeclarations in order to get the prefix association.

See documentation and sample below:

[XmlRoot(ElementName = "person")] public class Person {     [XmlElement(Namespace = "http://example.com")]     public string fname;      [XmlElement(Namespace = "http://sample.com")]     public string lname;      [XmlNamespaceDeclarations]     public XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();      public Person()     {         xmlns.Add("a", "http://example.com");         xmlns.Add("b", "http://sample.com");     } }
