XML序列化的时候如何支持Namespace

我曾经不止一次（当然不仅仅是我意识到这个问题）说到过，XML标准中的Namespace的设计其实是一个较为失败的设计，它有它的优点，但缺点更多。

这里又有一个范例。我们需要在XML序列化的时候，更加小心地注意namespace的问题。

下面有一个例子程序

数据实体模型（这个类是通过xsd工具自动生成的，具体用途这里就不做展开了
//------------------------------------------------------------------------------
// <auto-generated>
//     This code was generated by a tool.
//     Runtime Version:4.0.30319.18444

using System.Xml.Serialization;

//
// This source code was auto-generated by xsd, Version=4.0.30319.33440.
//

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.33440")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-08-15T22:37:24")]
[System.Xml.Serialization.XmlRootAttribute(Namespace="http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-08-15T22:37:24", IsNullable=false)]
public partial class myFields {

    private string titleField;

    private System.Xml.XmlAttribute[] anyAttrField;

    /// <remarks/>
    public string Title {
        get {
            return this.titleField;
        }
        set {
            this.titleField = value;
        }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlAnyAttributeAttribute()]
    public System.Xml.XmlAttribute[] AnyAttr {
        get {
            return this.anyAttrField;
        }
        set {
            this.anyAttrField = value;
        }
    }
}
实际对应的XML文档应该是下面这样的。注意，下面有一个my的命名空间。
<?xml version="1.0" encoding="UTF-8"?><?mso-infoPathSolution solutionVersion="1.0.0.3" productVersion="15.0.0" PIVersion="1.0.0.0" href="file:///C:UserschenxizhangAppDataLocalMicrosoftInfoPathDesigner446fec1056ed24f25manifest.xsf" ?><?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.4"?><my:myFields xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-08-15T22:37:24" xml:lang="en-us">
<my:Title>test</my:Title>
</my:myFields>
为了使得XML序列化的时候，正常地生成这样的一份文档。我们需要做如下的特殊设计

using System;
using System.IO;
using System.Xml.Serialization;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            //1.准备数据
            var data = new myFields() { Title = "CEO" };
            //2.准备命名空间
            var ns = new XmlSerializerNamespaces();
            ns.Add("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-08-15T22:37:24");
            //3.准备序列化器
            var serializer = new XmlSerializer(typeof(myFields));
            //4.准备用来接收的内存流
            var ms = new MemoryStream();
            //5.执行序列化
            serializer.Serialize(ms, data, ns);

            //6.将内容读取出来
            var reader = new StreamReader(ms);
            ms.Position = 0;
            Console.WriteLine(reader.ReadToEnd());
            //7.关闭流
            reader.Close();
            ms.Close();

            Console.Read();
        }
    }
}

不太难，但是确实是多了些步骤，不是吗
