Xml Serializer-顶级元素上的默认名称空间 [英] Xml Serializer - Default namespace on top-level Element

问题描述

我使用XmlSerializer，我正在寻找一种在顶层Element上设置默认XML名称空间的方法.我希望正确的方法是在顶级类的XmlType属性中指定此方法.但是，名称空间仅适用于此类的子级.例如，请参见下面的C#代码，它序列化了一个简单的嵌套结构:

Hi,

I use the XmlSerializer and I''m looking for a way to set the default XML namespace on the top level Element. The correct way to do this, I hoped, was to specify this in an XmlType attribibute on the top level class. However, the namespace is only applied to the children of this class. For example, see the C# code below that serializes a simple nested structure:

// Contained class.<br />    public class Circle<br />    {<br />    }<br /><br />    // Container class.<br />    [XmlType(Namespace="http://mbshapes.com")] // Why does the Shapes element not use this namespace?<br />    public class Shapes<br />    {<br />        private Circle _circle = new Circle();<br /><br />        public Circle Circle<br />        {<br />            get<br />            {<br />                return _circle;<br />            }<br />            set<br />            {<br />                _circle = value;<br />            }<br />        }<br />    }<br /><br />    // Serialize Shapes object.<br />    public class SerializeTest<br />    {<br />        public static void Serialize()<br />        {<br />            // Create Shapes object.<br />            Shapes shapes = new Shapes();<br /><br />            // Open file.<br />            using (TextWriter textWriter = new StreamWriter("Shapes.xml"))<br />            {                <br />                // Serialize.<br />                XmlSerializer xmlSerializer = new XmlSerializer(typeof(Shapes));<br />                xmlSerializer.Serialize(textWriter, shapes);<br />            }<br />        }<br />    }

输出是这样的:

The output is this:

<?xml version="1.0" encoding="utf-8"?><br /><Shapes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><br />  <Circle xmlns="http://mbshapes.com" /><br /></Shapes>

我所期望的(以及我所需要的)是这样的:

What I expected (and what I need), is something like this:

<br /><?xml version="1.0" encoding="utf-8"?><br /><Shapes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://mbshapes.com"><br />  <Circle /><br /></Shapes><br />

我做错了什么吗?还是有任何解决方法?

谢谢.

Am I doing something wrong? Or are there any work-arounds?

Thanks.

推荐答案

尝试

[<code>XmlRoot</code>(Namespace = "http://mbshapes.com")]<br />    public class Shapes<br />    {<br />        private Circle _circle = new Circle();<br /><br />        public Circle Circle<br />        {<br />            get<br />            {<br />                return _circle;<br />            }<br />            set<br />            {<br />                _circle = value;<br />            }<br />        }<br />    }
