在C#中，使用XML序列化处理复杂对象主要涉及到以下几个方面：
- 定义复杂对象类：首先，你需要定义一个包含多个属性和子对象的类。这些属性和子对象可以是基本数据类型、枚举、集合（如List或Array）或其他自定义类。
public class Person { public string Name { get; set; } public int Age { get; set; } public Address Address { get; set; } public List<string> Hobbies { get; set; } } public class Address { public string Street { get; set; } public string City { get; set; } public string PostalCode { get; set; } } - 添加XML序列化属性：为了控制XML序列化过程中的元素名称、命名空间等，你可以为类和属性添加
XmlElement、XmlAttribute、XmlRoot等特性。
[XmlRoot("Person")] public class Person { [XmlElement("Name")] public string Name { get; set; } [XmlElement("Age")] public int Age { get; set; } [XmlElement("Address")] public Address Address { get; set; } [XmlElement("Hobbies")] public List<string> Hobbies { get; set; } } [XmlRoot("Address")] public class Address { [XmlElement("Street")] public string Street { get; set; } [XmlElement("City")] public string City { get; set; } [XmlElement("PostalCode")] public string PostalCode { get; set; } } - 序列化对象：使用
XmlSerializer类将复杂对象序列化为XML字符串。
Person person = new Person { Name = "John Doe", Age = 30, Address = new Address { Street = "123 Main St", City = "New York", PostalCode = "10001" }, Hobbies = new List<string> { "Reading", "Traveling" } }; XmlSerializer serializer = new XmlSerializer(typeof(Person)); StringWriter writer = new StringWriter(); serializer.Serialize(writer, person); string xmlString = writer.ToString(); - 反序列化XML：使用
XmlSerializer类将XML字符串反序列化为复杂对象。
string xmlString =<Person><Name>John Doe</Name><Age>30</Age<Address><Street>123 Main St</Street><City>New York</City><PostalCode>10001</PostalCode></Address><Hobbies<string>Reading</string<string>Traveling</string></Hobbies></Person>"; XmlSerializer serializer = new XmlSerializer(typeof(Person)); StringReader reader = new StringReader(xmlString); Person deserializedPerson = (Person)serializer.Deserialize(reader); 通过以上步骤，你可以实现复杂对象的XML序列化和反序列化。注意，在处理更复杂的对象时，可能需要处理继承、抽象类、接口等高级概念。在这些情况下，你可能需要使用XmlInclude、XmlType等特性来指定相关类型。
