C# XML序列化去掉xmlns和xmlns属性

//准备序化列对象

XmlSerializer xs = new XmlSerializer(obj.GetType());

MemoryStream ms = new MemoryStream();

//设置序序化XML格式

XmlWriterSettings xws = new XmlWriterSettings();

xws.Indent = true;

xws.OmitXmlDeclaration = true;

xws.Encoding = Encoding.UTF8;

XmlWriter xtw = XmlTextWriter.Create(ms, xws);

//去掉要结点的 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" 属性

XmlSerializerNamespaces _namespaces = new XmlSerializerNamespaces(

new XmlQualifiedName[] {

new XmlQualifiedName(string.Empty, "aa")

});

xs.Serialize(xtw, obj,_namespaces);

ms.Position = 0;

xmlDoc = new XmlDocument();

xmlDoc.Load(ms);

//给文档添加<?xml version="1.0" encoding="utf-8"?>

XmlDeclaration xmlDecl = xmlDoc.CreateXmlDeclaration("1.0", "utf-8", null);

xmlDoc.InsertBefore(xmlDecl, xmlDoc.DocumentElement);
