XML序列化CDATA

不可避免的遇到对接需要使用XML文档的第三方系统，某些节点内容特殊，序列化时需特殊处理，解决方案是实现IXmlSerializable接口。

/// <summary>
    /// Person
    /// </summary>
    public class Person : IXmlSerializable
    {
        /// <summary>
        /// PersonId
        /// </summary>
        public int PersonId { get; set; }
        /// <summary>
        /// PersonName
        /// </summary>
        public string PersonName { get; set; }
        /// <summary>
        /// Birthday
        /// </summary>
        public DateTime? Birthday { get; set; }
        /// <summary>
        /// Age
        /// </summary>
        public int Age { get; set; }
        /// <summary>
        /// Remarks
        /// </summary>
        public string Remarks { get; set; }

        public XmlSchema GetSchema()
        {
            return default(XmlSchema);
        }

        public void ReadXml(XmlReader reader)
        {
            reader.ReadStartElement("Person");
            this.PersonId = reader.ReadElementContentAsInt("PersonId","");
            this.PersonName = reader.ReadElementContentAsString("PersonName","");
            this.Birthday = reader.ReadElementContentAsDateTime("Birthday", "");
            this.Age = reader.ReadElementContentAsInt("Age", "");
            this.Remarks = reader.ReadElementContentAsString("Remarks", "");
        }

        public void WriteXml(XmlWriter writer)
        {
            writer.WriteStartElement(nameof(this.PersonId));
            writer.WriteValue(this.PersonId);
            writer.WriteEndElement();

            writer.WriteStartElement(nameof(this.PersonName));
            writer.WriteCData(this.PersonName);
            writer.WriteEndElement();

            writer.WriteStartElement(nameof(this.Birthday));
            writer.WriteValue(this.Birthday);
            writer.WriteEndElement();

            writer.WriteStartElement(nameof(this.Age));
            writer.WriteValue(this.Age);
            writer.WriteEndElement();

            writer.WriteStartElement(nameof(this.Remarks));
            writer.WriteCData(this.Remarks);
            writer.WriteEndElement();

        }
    }

序列化：

　　　　　　　XmlSerializer serializer = new XmlSerializer(typeof(Person));

            Person person = new Person();
            person.PersonId = ;
            person.PersonName = chinesenames[];
            person.Birthday = RandomUtils.RandomDateTime(DateTime.Now.AddYears(-), DateTime.Now);
            person.Age = DateTime.Now.Year - person.Birthday.GetValueOrDefault().Year;
            person.Remarks = "https://blog.csdn.net/shuliuzh/article/details/49426711";

            using(MemoryStream writer=new MemoryStream())
            {
                serializer.Serialize(writer, person);
               string xml= Encoding.UTF8.GetString(writer.GetBuffer());
                Console.WriteLine(xml);
                File.WriteAllText("person.xml", xml, Encoding.UTF8);
            }

结果：

<?xml version="1.0"?>
<Person>
  <PersonId>1</PersonId>
  <PersonName><![CDATA[闾丘寇态]]></PersonName>
  <Birthday>1985-05-24T00:00:00</Birthday>
  <Age>33</Age>
  <Remarks><![CDATA[https://blog.csdn.net/shuliuzh/article/details/49426711]]></Remarks>
</Person>
