练习反射,对象序列化与反序列化

Person p1 = new Person();
            p1.Age = 22;
            p1.Name = "齐达内";

            //对象序列化
            using (Stream st = File.OpenWrite(@"D:\22.xml"))
            {
                BinaryFormatter bf = new BinaryFormatter();
                bf.Serialize(st, p1);
                Console.WriteLine("成功");
               
            }

using (Stream st = File.OpenRead(@"D:\22.xml"))
            {
              BinaryFormatter bf = new BinaryFormatter();
              object ob =bf.Deserialize(st);//得到的是一个object的对象
             Type t = ob.GetType();
            XElement person = new XElement(t.Name);//获取Person
            //遍历所有公有字段
            PropertyInfo[] properinfo = t.GetProperties();
            foreach (var p in properinfo)
            {
                XElement name = new XElement(p.Name);
                name.Value = p.GetValue(ob, null).ToString();//字段值怎么取出来
                person.Add(name);
            }
            string xml = person.ToString();
              using (Stream st1 = File.OpenWrite(@"D:\person.xml"))
              {
                  byte[] bytes=new byte[1024];
                  bytes = Encoding.UTF8.GetBytes(xml);
                  st1.Write(bytes, 0, bytes.Length);
              }
            }
