これは私のコードです:

XElement itemsElement = new XElement("Items", string.Empty);
//some code
parentElement.Add(itemsElement);

その後、私はこれを得ました:

<Items xmlns=""></Items>

親要素には名前空間がありません。Items空の名前空間属性のない要素を取得するにはどうすればよいですか?

It's all about how you handle your namespaces. The code below creates child items with different namespaces:

XNamespace defaultNs = "http://www.tempuri.org/default";
XNamespace otherNs = "http://www.tempuri.org/other";

var root = new XElement(defaultNs + "root");
root.Add(new XAttribute(XNamespace.Xmlns + "otherNs", otherNs));

var parent = new XElement(otherNs + "parent");
root.Add(parent);

var child1 = new XElement(otherNs + "child1");
parent.Add(child1);

var child2 = new XElement(defaultNs + "child2");
parent.Add(child2);

var child3 = new XElement("child3");
parent.Add(child3);

It will produce XML that looks like this:

<root xmlns:otherNs="http://www.tempuri.org/other" xmlns="http://www.tempuri.org/default">
    <otherNs:parent>
        <otherNs:child1 />
        <child2 />
        <child3 xmlns="" />
    </otherNs:parent>
</root>

Look at the difference between child1, child2 and child3. child2 is created using the default namespace, which is probably what you want, while child3 is what you have now.
