Question

Using the .NET System.ServiceModel.Syndication classes…

I would like to add a new SyndicationElementExtension to a SyndicationItem that will export the following XML:

<media:thumbnail url="http://www.foo.com/keyframe.jpg" width="75" height="50" time="12:05:01.123" />

Something along the lines of:

syndicationItem.ElementExtensions.Add(new SyndicationElementExtension("thumbnail", "http://video.search.yahoo.com/mrss", ?

How do you create a simple SyndicationElementExtension with a few attributes?

The
SyndicationElementExtensionCollection
class can also be used to create
element extensions from an XmlReader
instance. This allows for easy
integration with XML processing APIs
such as XElement as shown in the
following sample code.

feed.ElementExtensions.Add(new XElement("xElementExtension",
        new XElement("Key", new XAttribute("attr1", "someValue"), "Z"),
        new XElement("Value", new XAttribute("attr1", "someValue"), 
        "15")).CreateReader());
