XElement命名空间（如何？）

在LINQ to XML中非常简单：

XNamespace ns = "sphinx";XElement element = new XElement(ns + "docset");

或者使“别名”正常工作，使其看起来像您的示例，如下所示：

XNamespace ns = "http://url/for/sphinx";XElement element = new XElement("container",    new XAttribute(XNamespace.Xmlns + "sphinx", ns),    new XElement(ns + "docset",        new XElement(ns + "schema"), new XElement(ns + "field", new XAttribute("name", "subject")), new XElement(ns + "field", new XAttribute("name", "content")), new XElement(ns + "attr",    new XAttribute("name", "published"),   new XAttribute("type", "timestamp"))));

产生：

<container xmlns:sphinx="http://url/for/sphinx">  <sphinx:docset>    <sphinx:schema />    <sphinx:field name="subject" />    <sphinx:field name="content" />    <sphinx:attr name="published" type="timestamp" />  </sphinx:docset></container>
