在C#中,处理复杂数据时,可以使用System.Runtime.Serialization命名空间下的类来进行序列化和反序列化。以下是一个简单的示例,展示了如何使用这些类处理包含自定义对象和集合的复杂数据。

首先,创建一个自定义类Person

using System.Runtime.Serialization;  [DataContract] public class Person {     [DataMember]     public string Name { get; set; }      [DataMember]     public int Age { get; set; }      [DataMember]     public Address Address { get; set; } }  [DataContract] public class Address {     [DataMember]     public string Street { get; set; }      [DataMember]     public string City { get; set; }      [DataMember]     public string State { get; set; } } 

这里,我们使用[DataContract]属性标记类,以便在序列化和反序列化过程中包含这些类的成员。[DataMember]属性用于指定要序列化和反序列化的成员。

接下来,创建一个包含自定义对象集合的类People

using System.Collections.Generic; using System.Runtime.Serialization;  [DataContract] public class People {     [DataMember]     public List<Person> Persons { get; set; } } 

现在,我们可以使用DataContractSerializer类进行序列化和反序列化:

using System; using System.IO; using System.Runtime.Serialization;  class Program {     static void Main()     {         // 创建一个包含自定义对象集合的实例         People people = new People         {             Persons = new List<Person>             {                 new Person { Name = "Alice", Age = 30, Address = new Address { Street = "123 Main St", City = "New York", State = "NY" } },                 new Person { Name = "Bob", Age = 25, Address = new Address { Street = "456 Elm St", City = "Los Angeles", State = "CA" } }             }         };          // 序列化对象         DataContractSerializer serializer = new DataContractSerializer(typeof(People));         using (StringWriter writer = new StringWriter())         {             serializer.WriteObject(writer, people);             string serializedData = writer.ToString();             Console.WriteLine("Serialized data:");             Console.WriteLine(serializedData);         }          // 反序列化对象         using (StringReader reader = new StringReader(serializedData))         {             People deserializedPeople = (People)serializer.ReadObject(reader);             Console.WriteLine("\nDeserialized data:");             foreach (Person person in deserializedPeople.Persons)             {                 Console.WriteLine($"Name: {person.Name}, Age: {person.Age}, Address: {person.Address.Street}, {person.Address.City}, {person.Address.State}");             }         }     } } 

这个示例中,我们首先创建了一个包含两个Person对象的People实例。然后,我们使用DataContractSerializer将对象序列化为字符串,再将字符串反序列化为对象。

注意:在实际应用中,你可能需要处理更复杂的数据结构和类型,例如嵌套的对象、集合和字典等。这个示例展示了如何使用DataContractSerializer处理这些情况。
