序列化与反序列化
建立Man.cs
using System.Xml.Serialization;
///<summary>
///Man 的摘要说明
///</summary>
[Serializable]
public class Man
{
public Man() {
}
[XmlElement("Man_Age")]
public int Age
{
get;
set;
}
public string Name
{
get;
set;
}
public string tel
{
get;
set;
}
public Man(int Age, string Name ,string tel)
{
this.Age = Age;
this.Name = Name;
this.tel = tel;
}
public string Show()
{
return String.Format(" Name : {0} Age: {1} tel :{2}", this.Name, this.Age,this.tel);
}
public void AddData(int Age, string Name, string tel)
{
this.Age = Age;
this.Name = Name;
this.tel = tel;
}
}
1.二进制格式序列化
首先引入
using System.Runtime.Serialization.Formatters.Binary;
然后通过
string Path = "C:\\man.text";
Man m=new Man (18,"小王1","18618618618");
FileStream fs = new FileStream(Path, FileMode.Create);
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(fs,m);
fs.Close();
二进制序列化反序列化
string Path = "C:\\man.text";
Man m = null;
FileStream fs = new FileStream(Path,FileMode.Open);
BinaryFormatter formatter = new BinaryFormatter();
m = formatter.Deserialize(fs) as Man ;//
fs.Close();
return m.Show();
2.XML序列化
string Path = "C:\\man.xml";
Man m = new Man();
m.AddData(18, "小王333", "18618618618");
using (StreamWriter fs = new StreamWriter (Path))
{
XmlSerializer xmlSerializer = new XmlSerializer(m.GetType());
xmlSerializer.Serialize(fs, m);
}
xml反序列化
string Path = "C:\\man.xml";
Man m = new Man ();
FileStream fs = new FileStream(Path,FileMode.Open);
XmlSerializer xmlSerializer = new XmlSerializer(m.GetType());
m = xmlSerializer.Deserialize(fs) as Man ;//
fs.Close();
return m.Show();
插曲： 可以通过 [NonSerialized] 对对象中的的部分数据取消序列化 做到部分暴露
如果声明一个类 而没有共有字段 那么这个类进行xml序列化的时候 将无法把数据写入xml文件
public class XMLserializeHelp { public static void Serialize<T>(string path, T t) where T:class { using (StreamWriter sw = new StreamWriter(path)) { XmlSerializer xml = new XmlSerializer(t.GetType()); xml.Serialize(sw, t); } } public static T Deserialize<T>(string path) where T:class { T t = default(T); FileStream fs = new FileStream(path, FileMode.Open); XmlSerializer xmlSerializer = new XmlSerializer(t.GetType()); t = xmlSerializer.Deserialize(fs) as T; fs.Close(); return t; } }
