序列化、反序列化的使用

  序列化、反序列化的使用
  调用:
  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。

  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> www.yztrans.com
  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;
  }
  }
  }}
