二进制序列化器:序列化结果人看不懂,但是序列化后体积小soap序列化器:人能看懂,没啥阅读体验,文件体积比较大


序列化方式说明

  • 二进制序列化器:序列化结果人看不懂,但是序列化后体积小

  • soap序列化器:人能看懂,没啥阅读体验,文件体积比较大

  • xml序列化器:可阅读性好,体积中等

  • 序列化为json格式

二进制序列化器

  • 要序列化的实体必须标记[Serializable]特性,表示可以序列化
  • 不想序列化的字段可以标记[NonSerialized]特性

实体

[Serializable] public class People {     public int Id;     public string Name;     public string Address;      [NonSerialized]     public string Sex; } 

序列化

List<People> peoples = GetPeoples();//创建一个实体集合 string fileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "log", "BinarySerialize.txt"); using (FileStream fs = new FileStream(fileName,FileMode.OpenOrCreate, FileAccess.ReadWrite)) {     BinaryFormatter formatter = new BinaryFormatter();     formatter.Serialize(fs, peoples); } 

反序列化

string fileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "log", "BinarySerialize.txt"); using (FileStream fs = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite)) {     BinaryFormatter formatter = new BinaryFormatter();     List<People> peoples = formatter.Deserialize(fs) as List<People>; }

soap序列化器

  • 要序列化的实体必须标记[Serializable]特性,表示可以序列化
  • 不想序列化的字段可以标记[NonSerialized]特性
  • soap不能序列化泛型对象

实体

[Serializable] public class People {     public int Id;     public string Name;     public string Address;      [NonSerialized]     public string Sex; } 

序列化

List<People> peoples = GetPeoples(); string fileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "log", "SoapSerialize.txt"); using (FileStream fs = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite)) {     SoapFormatter formatter = new SoapFormatter();     formatter.Serialize(fs, peoples.ToArray()); } 

反序列化

string fileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "log", "SoapSerialize.txt"); using (FileStream fs = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite)) {     SoapFormatter formatter = new SoapFormatter();     People[] peoples = (People[])formatter.Deserialize(fs); } 

序列化结果

XML序列化器

  • 创建XML序列化器时需要传入需要序列化的对象的类型
  • 不想序列化的字段可以标记[XmlIgnore]特性

实体

public class People {     public int Id;     [XmlElement(ElementName = "姓名")]//设置节点别名     public string Name;     [XmlIgnore]//忽略Address不进行序列化     public string Address;      [XmlAttribute(AttributeName = "性别")]//设置这个字段作为xml中的属性出现,并设置了属性名称     public string Sex; } 

序列化

List<People> peoples = GetPeoples(); string fileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "log", "XmlSerialize.xml"); using (FileStream fs = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite)) {     XmlSerializer formatter = new XmlSerializer(typeof(List<People>));     formatter.Serialize(fs, peoples); } 

反序列化

string fileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "log", "XmlSerialize.xml"); using (FileStream fs = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.ReadWrite)) {     XmlSerializer formatter = new XmlSerializer(typeof(List<People>));     List<People> peoples = (List<People>)formatter.Deserialize(fs); } 

序列化结果

<?xml version="1.0"?> <ArrayOfPeople xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">   <People 性别="男">     <Id>1</Id>     <姓名>张三</姓名>   </People>   <People 性别="女">     <Id>2</Id>     <姓名>李四</姓名>   </People>   <People 性别="男">     <Id>3</Id>     <姓名>王五</姓名>   </People> </ArrayOfPeople> 

序列化为Json格式

  • 安装Nuget包Newtonsoft.Json

序列化和反序列化

List<People> peoples = GetPeoples(); string json = JsonConvert.SerializeObject(peoples);  List<People> newPeople = JsonConvert.DeserializeObject<List<People>>(json); 

序列化结果

[{"Id":1,"Name":"张三","Address":"江苏"},{"Id":2,"Name":"李四","Address":"安徽"},{"Id":3,"Name":"王五","Address":"浙江"}]
