.NET对象序列化的几种方式

设有对象：

 

public class Person
    {
        public string Name
        {           
            get; set;       
        }
        public int Age
        {
            get; set;
        }
        public string Address
        {
            get; set;
        }
    }
  Person p = new Person{Name = "McJeremy",Age = 25, Address = "ShenZhen"};

 

现在使用以下几种方式对其序列化： 

1、使用 BinaryFormatter

 

FileStream fs = new FileStream(@"D:/person.txt", FileMode.OpenOrCreate, FileAccess.Write);
            BinaryFormatter bf = new BinaryFormatter();
            try
            {
                bf.Serialize(fs, p);
//反序列化 object obj=bf.Deserialize(fs)
                fs.Close();
            }
            catch
            {
            }

 

2、使用XmlSerializer

 

FileStream fs = new FileStream(@"D:/person.xml", FileMode.OpenOrCreate, FileAccess.Write);
            XmlSerializer xs = new XmlSerializer(typeof(Person));
            try
            {
                xs.Serialize(fs, p);
                //反序列化 object obj=xs.Deserialize(fs)
                fs.Close();
            }
            catch
            {
            }

 

序列化结果：

 

<?xml version="1.0"?>
<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Name>Xu</Name>
  <Age>25</Age>
  <Address>ShenZhen</Address>
</Person>

 

/***使用DataContract及DataContractJson时，需要在Person类及其属性上添加DataContract&&DataMember属性，如下：

 

[DataContract]
    public class Person
    {
        [DataMember(Order=1)]
        public string Name
        {
            get;
            set;
        }
        [DataMember(Order = 2)]
        public int Age
        {
            get;
            set;
        }
        [DataMember(Order = 3)]
        public string Address
        {
            get;
            set;
        }
    } 

 

 

3、使用DataContractSerializer(结果存为xml格式 ）

 

 using (FileStream fs = new FileStream(@"D:/person_DataContract.xml", FileMode.OpenOrCreate, FileAccess.Write))
            {
                DataContractSerializer ds = new DataContractSerializer(typeof(Person));
                ds.WriteObject(fs, p);
            }

//结果：
 <Person xmlns="http://schemas.datacontract.org/2004/07/ConsoleApplication1" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><Name>Xu</Name><Age>25</Age><Address>ShenZhen</Address></Person>

 

 

4、在System.ServiceModel.web.dll中，还有个DataContractJsonSerializer，结果存为Json格式

 using (FileStream fs = new FileStream(@"D:/person_DataContractJson.txt", FileMode.OpenOrCreate, FileAccess.Write))
            {
                DataContractJsonSerializer ds = new DataContractJsonSerializer(typeof(Person));
                ds.WriteObject(fs, p);
            }
//结果：
{"Name":"McJeremy","Age":25,"Address":"ShenZhen"}
