C#调用XmlSerializer序列化时生成CDATA节点解决方法

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }        
}

引用内容

<?xml version="1.0"?>
<Person xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Name>dnawo</Name>
  <Age>100</Age>
</Person>

例2

复制内容到剪贴板程序代码

public class Person
{
    public XmlNode Name { get; set; } //XmlNodeType.CDATA
    public XmlNode Age { get; set; } //XmlNodeType.Text
}

引用内容

<?xml version="1.0"?>
<Person xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Name><![CDATA[dnawo]]></Name>
  <Age>100</Age>
</Person>

例1的实体类我们比较常用，赋值取值方便，但序列化时不能生成CDATA节点，例2的实体类序列化时可以生成CDATA节点，但使用不方便，于是将两个例子优点做了下结合：

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

namespace ConsoleApplication1
{
    public partial class Person
    {
        [XmlIgnore]
        public string Name { get; set; }        

        [XmlIgnore]
        public int Age { get; set; }        
    }

    public partial class Person
    {
        [XmlElement("Name")]
        public XmlNode aaa
        {
            get
            {
                XmlNode node = new XmlDocument().CreateNode(XmlNodeType.CDATA, "", "");
                node.InnerText = Name;
                return node;
            }
            set { } //省略则aaa不会被序列化
        }
        [XmlElement("Age")]
        public XmlNode bbb
        {
            get
            {
                XmlNode node = new XmlDocument().CreateNode(XmlNodeType.Text, "", "");
                node.InnerText = Age.ToString();
                return node;
            }
            set { } //省略则bbb不会被序列化
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            string result = string.Empty;
            Person person = new Person() { Name = "dnawo", Age = 100 };
            using (MemoryStream output = new MemoryStream())
            {
                XmlSerializer serializer = new XmlSerializer(person.GetType());
                serializer.Serialize(output, person);
                result = Encoding.UTF8.GetString(output.ToArray());
            }
            Console.WriteLine(result);

            Console.ReadKey();
        }
    }
}

常见问题

问：为什么例2实体类属性类型不直接用XmlCDataSection、XmlText？
答：用XmlCDataSection没问题，而XmlText序列化时会失败，提示反射类型“System.Xml.XmlText”出错。
