c# - LINQ to XML - accessing descendants with a prefix

Question

I have a sample xml file like this

<vs:BioData>
<vs:Name>Name</vs:Name>
<vs:Address>address</vs:Address>
<vs:Zip>Zip</vs:zip>
</vs:BioData>

All the nodes have a prefix value as vs and can anyone tell me how would I go about parsing this file to read Name and Address Information? I am very new to LINQ. Any help on this would be greatly appreciated.

Thanks!

You need to know what the namespace is. That will have been declared earlier, with something like:

xmlns:vs="http://some_url_here"

You can query using XNamespace:

XNamespace vs = "http://some_url_here";
var names = doc.Descendants(vs + "Name")
               .Select(x => (string) x)
               .ToList();

The + here is actually converting an XNamespace and a string to an XName.
