在code是这样的：

  StringBuilder的建设者=新的StringBuilder（）;
XmlWriterSettings设置=新XmlWriterSettings（）;
settings.OmitXmlDeclaration = TRUE;
使用（的XmlWriter的XmlWriter = XmlWriter.Create（建设者，设置））
{
    XmlSerializer的S =新的XmlSerializer（objectToSerialize.GetType（））;
    s.Serialize（XMLWriter的，objectToSerialize）;
}
 

由此产生的序列化文件包括命名空间，就像这样：

 ＆LT;消息的xmlns：XSI = HTTP：//www.w3.org/2001/XMLSchema-instance 
    的xmlns：XSD = HTTP：//www.w3.org/2001/XMLSchema 
    的xmlns =金塔：什么＆GT;
 ...
＆LT; /消息＆GT;
 

要删除XSI和XSD的命名空间，我可以按照回答如何没有得到的xmlns =...序列化对象到XML？ 。

我希望我的邮件标记为＆LT;消息＆GT; （不带任何命名空间属性）。我怎样才能做到这一点？

  ...
XmlSerializer的S =新的XmlSerializer（objectToSerialize.GetType（））;
XmlSerializerNamespaces NS =新XmlSerializerNamespaces（）;
ns.Add（，）;
s.Serialize（XMLWriter的，objectToSerialize，NS）;
 

The code looks like this:

StringBuilder builder = new StringBuilder();
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
using (XmlWriter xmlWriter = XmlWriter.Create(builder, settings))
{
    XmlSerializer s = new XmlSerializer(objectToSerialize.GetType());
    s.Serialize(xmlWriter, objectToSerialize);
}

The resulting serialized document includes namespaces, like so:

<message xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
    xmlns="urn:something">
 ...
</message>

To remove the xsi and xsd namespaces, I can follow the answer from How to serialize an object to XML without getting xmlns="…"?.

I want my message tag as <message> (without any namespace attributes). How can I do this?

...
XmlSerializer s = new XmlSerializer(objectToSerialize.GetType());
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("","");
s.Serialize(xmlWriter, objectToSerialize, ns);
