本文介绍了一个使用 C# 实现的对象序列化示例。通过 DataContractJsonSerializer 类将对象数组转换为 JSON 格式字符串，并能将字符串反序列化回原始对象。文章提供了完整的代码实现，包括自定义类 A 的序列化与反序列化过程。

These two methods are tool methods, they are very useful. Below code's demo is about object array serialisation. So theGetknowTypes method is used in the constructor of the class namedDataContractJsonSerializer

The project demo the serialisation of object.

using System.Collections.Generic;
using System.IO;
using System.Runtime.Serialization.Json;
using System.Text;

            string value = SerializeObject<object[]>(obj1);

            Console.WriteLine("Object string: "+value);

            object[] obj2 = DeserializeString<object[]>(value);

            Console.WriteLine("Object: "+obj2);

            object[] obj3 = new[] { new A() };

            ((A)DeserializeString<object[]>(SerializeObject<object[]>(obj3))[0]).Speak();

            Console.ReadLine();
        }
