In C# is it possible to serialize empty string as nil value. Let's take the object like this:
var myBook = new Book(){ Author = "John S.", ISBN = null };
I'd like to have:
<Book>
<Author>John S.</Author>
<ISBN nil="true"/>
</Book>
Is it possible to achieve such a result with one of third party xml serializers like ExtendedXmlSerializer or YAXLib?
Regards.
You can try this :
var myBook = new Book() { Author = "John S.", ISBN = null };
XmlSerializer xs = new XmlSerializer(typeof(Book));
StringWriter sw = new StringWriter();
xs.Serialize(sw, myBook);
Console.WriteLine(sw.ToString() );
Also you need to add an attribute :
public class Book
{
public string Author { get; set; }
[System.Xml.Serialization.XmlElement(IsNullable = true)]
public string ISBN { get; set; }
}
Result :
<?xml version="1.0" encoding="utf-16"?>
<Book xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Author>John S.</Author>
<ISBN xsi:nil="true" />
</Book>
