读取含有命名空间xml文件内容

.NET Language-Integrated Query for XML Data

XNamespace myNs = "http://mycompany.com";

XElement contacts =
   new XElement(myNs + "contacts",
      new XElement(myNs + "contact",
         new XElement(myNs + "name", "Patrick Hines"),
         new XElement(myNs + "phone", "206-555-0144", 
             new XAttribute("type", "home")),
         new XElement(myNs + "phone", "425-555-0145",
             new XAttribute("type", "work")),
         new XElement(myNs + "address",
            new XElement(myNs + "street1", "123 Main St"),
            new XElement(myNs + "city", "Mercer Island"),
            new XElement(myNs + "state", "WA"),
            new XElement(myNs + "postal", "68042")
         )
      )
   );

 

产生如下文件：在最上层指定命名空间，分节点默认还有父节点的命名空间*继承性）

<contacts xmlns="http://mycompany.com">
   <contact>
      <name>Patrick Hinesname>
      <phone type="home">206-555-0144phone>
      <phone type="work">425-555-0145phone>
      <address>
