Is there a way to set the default namespace to query from an XDocument?

I don't want to include xmlns + "ElementName" for every element name?

XDocument xml = XDocument.Load(@"C:\file.xml");
XNamespace xmlns = "http://www.com/namespace";
var vehicles = from vehicle in开发者_C百科 xml.Descendants(xmlns + "Element")
               select vehicle.Element(xmlns + "Item")
};

Unfortunately this is what you must do when working with LINQ to XML. You must provide the namespace each time you query the document for a particular element.

Looks like Scott Hanselman has written some notes on it a while ago. Not exactly what you are lookin for, maybe (there are some Linq to XML examples a bit down in the post), but here's the link, anyhow: http://www.hanselman.com/blog/GetNamespacesFromAnXMLDocumentWithXPathDocumentAndLINQToXML.aspx

Even it is too late but maybe it helps someone else like me!

You can add an extention method to act as a wrapper for the built in one!

Like so:

public static class XDoncumentExtentions
{
    private static string DefaultNamespace = "{http://schemas.openxmlformats.org/spreadsheetml/2006/main}";
    public static IEnumerable<XElement> DescendantsSimple(this XContainer me, string simpleName)
    {
        return me.Descendants(string.Format("{0}{1}", DefaultNamespace, simpleName));
    }

    public static IEnumerable<XElement> ElementsSimple(this XContainer me, string simpleName)
    {
        return me.Elements(string.Format("{0}{1}", DefaultNamespace, simpleName));
    }

    public static XElement ElementSimple(this XContainer me, string simpleName)
    {
        return me.Element(string.Format("{0}{1}", DefaultNamespace, simpleName));
    }
}
