The MSDN documentation for Automatic Properties (a C# 3 language feature) states that attributes are not valid on automatic properties. This is not true, the following code compiles and works as expected:
public class Data
{
[XmlAttribute]
public int SomeNumber { get; set; }
}
class Program
{
static void Main(string[] args)
{
using (XmlWriter w = XmlWriter.Create(@”c:\temp\test.xml”))
{
XmlSerializer s = new XmlSerializer(typeof (Data));
s.Serialize(w, new Data { SomeNumber = 5 });
}
}
}
Running this code results in an XML file looking roughly like this (I stripped some unneeded namespace declarations):
< ?xml version="1.0" encoding="utf-8"?> <data SomeNumber="5" />
SomeNumber is saved as an attribute, so the XmlAttribute attribute worked correctly.
