C# - How to remove xmlns from XElement

问题

How can I remove the "xmlns" namespace from a XElement?

I tried: attributes.remove, xElement.Name.NameSpace.Remove(0), etc, etc. No success.

My xml:

<event xmlns="http://www.blablabla.com/bla" version="1.00">
  <retEvent version="1.00">
  </retEvent>
</event>

How can I accomplish this?

The accepted answer did not work for me because xelement.Attributes() was empty, it wasn't returning the namespace as an attribute.

The following will remove the declaration in your case:

element.Name = element.Name.LocalName;

If you want to do it recursively for your element and all child elements use the following:

    private static void RemoveAllNamespaces(XElement element)
    {
        element.Name = element.Name.LocalName;

        foreach (var node in element.DescendantNodes())
        {
            var xElement = node as XElement;
            if (xElement != null)
            {
                RemoveAllNamespaces(xElement);
            }
        }
    }

You could use IsNamespaceDeclaration to detect which attribute is a namespace

xelement.Attributes()
        .Where( e => e.IsNamespaceDeclaration)
        .Remove();
