序列化、反序列化的使用

using System;

namespace ConsoleApp_Serializable
{
    class Program
    {
        static void Main(string[] args)
        {
            Person mike = new Person() { Age = 21, Name = "Mike" };
            mike.NameChanged += mike_NameChanged;
            BinarySerializer.SerializeToFile(mike, @"c:\", "person.txt");
            Person p = BinarySerializer.DeserializeFromFile<Person>(@"c:\person.txt");
            p.Name = "rose";
            Console.WriteLine(p.Name);
            Console.WriteLine(p.Age.ToString());
            Console.ReadKey();
        }

        static void mike_NameChanged(object sender, EventArgs e)
        {
            Console.WriteLine("Name Changed !");
        }
    }

    [Serializable]
    class Person
    {
        private string name;
        public int Age { get; set; }

        public string Name
        {
            get { return name; }
            set
            {
                if (NameChanged != null)
                {
                    NameChanged(this, null);
                }
                name = value;
            }
        }

        //事件往往是不需要序列化的，反序列化的环境和序列化的环境往往不一致，这就失去了将事件序列化的意义。
        [field: NonSerialized]
        public event EventHandler NameChanged;
    }
}

工具类：

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

namespace ConsoleApp_Serializable
{
    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;
            }
        }
    }
