在C#中，處理復雜數(shù)據(jù)時，可以使用System.Runtime.Serialization命名空間下的類來進行序列化和反序列化。以下是一個簡單的示例，展示了如何使用這些類處理包含自定義對象和集合的復雜數(shù)據(jù)。

首先，創(chuàng)建一個自定義類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; }
}

這里，我們使用[DataContract]屬性標記類，以便在序列化和反序列化過程中包含這些類的成員。[DataMember]屬性用于指定要序列化和反序列化的成員。

接下來，創(chuàng)建一個包含自定義對象集合的類People：

using System.Collections.Generic;
using System.Runtime.Serialization;

[DataContract]
public class People
{
    [DataMember]
    public List<Person> Persons { get; set; }
}

現(xiàn)在，我們可以使用DataContractSerializer類進行序列化和反序列化：

using System;
using System.IO;
using System.Runtime.Serialization;

class Program
{
    static void Main()
    {
        // 創(chuàng)建一個包含自定義對象集合的實例
        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" } }
            }
        };

        // 序列化對象
        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);
        }

        // 反序列化對象
        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}");
            }
        }
    }
}

這個示例中，我們首先創(chuàng)建了一個包含兩個Person對象的People實例。然后，我們使用DataContractSerializer將對象序列化為字符串，再將字符串反序列化為對象。

注意：在實際應用中，你可能需要處理更復雜的數(shù)據(jù)結構和類型，例如嵌套的對象、集合和字典等。這個示例展示了如何使用DataContractSerializer處理這些情況。
