在C#中，可以使用多种方法进行XML序列化

使用XmlSerializer类：这是最常用的方法，通过创建XmlSerializer对象并调用其Serialize和Deserialize方法来实现对象的序列化和反序列化。

using System.IO; using System.Xml.Serialization;  public class Program {     public static void Main()     {         // 创建一个要序列化的对象         Person person = new Person { Name = "John", Age = 30 };          // 创建一个XmlSerializer对象         XmlSerializer serializer = new XmlSerializer(typeof(Person));          // 将对象序列化为XML字符串         using (StringWriter writer = new StringWriter())         {             serializer.Serialize(writer, person);             string xmlString = writer.ToString();             Console.WriteLine("Serialized XML: " + xmlString);         }          // 从XML字符串反序列化为对象         using (StringReader reader = new StringReader(xmlString))         {             Person deserializedPerson = (Person)serializer.Deserialize(reader);             Console.WriteLine("Deserialized object: Name = {0}, Age = {1}", deserializedPerson.Name, deserializedPerson.Age);         }     } }  public class Person {     public string Name { get; set; }     public int Age { get; set; } }

使用DataContractSerializer类：这是另一种用于序列化和反序列化对象的方法，主要用于WCF服务。与XmlSerializer相比，DataContractSerializer提供了更好的性能和更简洁的XML输出。

using System.IO; using System.Runtime.Serialization;  public class Program {     public static void Main()     {         // 创建一个要序列化的对象         Person person = new Person { Name = "John", Age = 30 };          // 创建一个DataContractSerializer对象         DataContractSerializer serializer = new DataContractSerializer(typeof(Person));          // 将对象序列化为XML字符串         using (MemoryStream stream = new MemoryStream())         {             serializer.WriteObject(stream, person);             string xmlString = Encoding.UTF8.GetString(stream.ToArray());             Console.WriteLine("Serialized XML: " + xmlString);         }          // 从XML字符串反序列化为对象         using (MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(xmlString)))         {             Person deserializedPerson = (Person)serializer.ReadObject(stream);             Console.WriteLine("Deserialized object: Name = {0}, Age = {1}", deserializedPerson.Name, deserializedPerson.Age);         }     } }  [DataContract] public class Person {     [DataMember]     public string Name { get; set; }      [DataMember]     public int Age { get; set; } }

使用XmlDocument或XDocument类：这些类提供了对XML文档的直接操作，允许您手动构建和解析XML结构。这种方法比使用序列化器更复杂，但提供了更大的控制和灵活性。

using System.Xml; using System.Xml.Linq;  public class Program {     public static void Main()     {         // 创建一个要序列化的对象         Person person = new Person { Name = "John", Age = 30 };          // 使用XDocument手动构建XML         XDocument doc = new XDocument(             new XElement("Person",                 new XElement("Name", person.Name),                 new XElement("Age", person.Age)             )         );          // 将XDocument转换为字符串         string xmlString = doc.ToString();         Console.WriteLine("Serialized XML: " + xmlString);          // 从XML字符串反序列化为对象         XDocument deserializedDoc = XDocument.Parse(xmlString);         Person deserializedPerson = new Person         {             Name = deserializedDoc.Root.Element("Name").Value,             Age = int.Parse(deserializedDoc.Root.Element("Age").Value)         };         Console.WriteLine("Deserialized object: Name = {0}, Age = {1}", deserializedPerson.Name, deserializedPerson.Age);     } }  public class Person {     public string Name { get; set; }     public int Age { get; set; } }
