序列化对象-优快云博客

本文介绍了一个用于ASP.NET应用程序中管理用户状态的方法。通过使用HttpCookie对象存储序列化的用户状态，并提供了设置和获取用户状态的功能。利用BinaryFormatter进行对象的序列化和反序列化，以便于存储和读取。

public static void setUserStat(Model.UserStat model)
   {
       HttpCookie cookie = new HttpCookie("bloghu");
       cookie.Expires = DateTime.Now.AddHours(1);
       cookie.Value = Serialize(model);
       System.Web.HttpContext.Current.Response.Cookies.Add(cookie);
   }
   public static Model.UserStat getCurrentUserStat()
   {
       if (System.Web.HttpContext.Current.Request.Cookies["bloghu"] != null)
           return (Model.UserStat)Deserialize(System.Web.HttpContext.Current.Request.Cookies["bloghu"].Value);
       else
           return new Model.UserStat();
   }
static string Serialize(object obj)
   {
       MemoryStream stream = new MemoryStream();
       BinaryFormatter formatter = new BinaryFormatter();
       formatter.Serialize(stream, obj);
       return Convert.ToBase64String(stream.ToArray());
   }
   static object Deserialize(string str)
   {
       BinaryFormatter formatter = new BinaryFormatter();
       MemoryStream stream = new MemoryStream(Convert.FromBase64String(str));
       return formatter.Deserialize(stream);
   }
