序列化：反序列化为另一个对象

将类型Person序列化为文件后，反序列化该文件为另一个类型PersonAnother,以下是相关代码：

 

using System;
using System.Runtime.Serialization;

namespace ConsoleApp_SerializableToAnotherObj
{
    class Program
    {
        static void Main(string[] args)
        {
            //反序列化为另一个对象
            Person personA=new Person(){FirstName = "Zhang",LastName = "San"};
            BinarySerializer.SerializeToFile(personA,@"c:","person.txt");
            PersonAnother p = BinarySerializer.DeserializeFromFile<PersonAnother>(@"c:person.txt");
            Console.WriteLine(p.Name);
            Console.ReadKey();
        }
    }

    [Serializable]
    class PersonAnother : ISerializable
    {
        public string Name { get; set; }
         
        protected PersonAnother(SerializationInfo info, StreamingContext context)
        {
            Name = info.GetString("Name");
        }

        void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
        {
        }
    }

    [Serializable]
    class Person : ISerializable
    {
        public string FirstName;
        public string LastName;
        public string ChineseName;

        public Person()
        {
        }
        protected Person(SerializationInfo info, StreamingContext context)
        { }

        void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
        {
            info.SetType(typeof(PersonAnother));
            info.AddValue("Name", string.Format("{0} {1}", LastName, FirstName));
        }
    }
}

工具类：

using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

namespace ConsoleApp_SerializableToAnotherObj
{
    public class BinarySerializer
    {
        /// <summary>
        /// 将类型序列化为字符串
        /// </summary>
        public static string Serialize<T>(T t)
        {
            using (MemoryStream stream = new MemoryStream())
            {
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(stream, t);
                return System.Text.Encoding.UTF8.GetString(stream.ToArray());
            }
        }

        /// <summary>
        /// 将类型序列化为文件
        /// </summary>
        public static void SerializeToFile<T>(T t, string path, string fullname)
        {
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
            string fullPath = string.Format(@"{0}{1}", path, fullname);
            using (FileStream stream = new FileStream(fullPath, FileMode.OpenOrCreate))
            {
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(stream, t);
                stream.Flush();
            }
        }

        /// <summary>
        /// 将字符串反序列化为类型
        /// </summary>
        public static TResult Deserialize<TResult>(string s) where TResult : class
        {
            byte[] bs = System.Text.Encoding.UTF8.GetBytes(s);
            using (MemoryStream stream = new MemoryStream(bs))
            {
                BinaryFormatter formatter = new BinaryFormatter();
                return formatter.Deserialize(stream) as TResult;
            }
        }

        /// <summary>
        /// 将文件反序列化为类型
        /// </summary>
        public static TResult DeserializeFromFile<TResult>(string path) where TResult : class
        {
            using (FileStream stream = new FileStream(path, FileMode.Open))
            {
                BinaryFormatter formatter = new BinaryFormatter();
                return formatter.Deserialize(stream) as TResult;
            }
        }
    }
