C# 如何在LINQ to XML中生成具有给定属性的XML头？

我需要使用LINQ to XML和C#复制以下XML头文件：

给了我一些我需要的东西

 <ns0:Subject_Sample xmlns:ns0="http://www.adventure-works.com"> 

但我得到的结果如下，奇怪的p1出现了

 <ns0:Subject_Sample xmlns:ns0="http://www.adventure-works.com" p1:schemaLocation="fhrb file:/fhrb.xsd" xmlns:p1="http://www.w3.org/2001/XMLSchema-instance"> 

问题是：如何通过LINQ到XML复制所需的头格式？这些属性的出现/消失/命名背后的逻辑是什么

试试这个：

XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
XNamespace ns0 = "fhrb";
XElement myTree = new XElement(ns0 + "Subject_Sample",
                                  new XAttribute(XNamespace.Xmlns + "xsi", xsi),
                                  new XAttribute(XNamespace.Xmlns + "ns0", ns0),
                                  new XAttribute(xsi + "schemaLocation", "fhrb file:FHRB_NEW_SUBJECT_SAMPLE.xsd")
                              );

XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
XNamespace ns0 = "http://www.adventure-works.com";
XElement myTree = new XElement(ns0 + "Subject_Sample",
new XAttribute(XNamespace.Xmlns + "ns0", "http://www.adventure-works.com" ),
            new XAttribute(xsi+"schemaLocation", "fhrb file:/fhrb.xsd")); 

 <ns0:Subject_Sample xmlns:ns0="http://www.adventure-works.com" p1:schemaLocation="fhrb file:/fhrb.xsd" xmlns:p1="http://www.w3.org/2001/XMLSchema-instance"> 

XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
XNamespace ns0 = "fhrb";
XElement myTree = new XElement(ns0 + "Subject_Sample",
                                  new XAttribute(XNamespace.Xmlns + "xsi", xsi),
                                  new XAttribute(XNamespace.Xmlns + "ns0", ns0),
                                  new XAttribute(xsi + "schemaLocation", "fhrb file:FHRB_NEW_SUBJECT_SAMPLE.xsd")
                              );
