序列化是將程式中的物件儲存到檔案串流的一種技術,C# 支持三種序列化機制,分別是 BinaryFormatter, SoapFormatter 與 XmlSerializer 等三種,其中前兩種可以反序列化,因此您若想用 XML 的方式序列化,可以使用 SoapFormatter。

以下程式是使用這三種技術進行序列化的範例。

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
using System.Runtime.Serialization.Formatters.Soap;
using System.Xml.Serialization;
using System.Collections;
[Serializable]
public class Radio {
 public bool hasTweeters;
 public bool hasSubWoofers;
 public double[] stationPresets;
 [NonSerialized]
 public string radioID = "001";
}
[Serializable]
public class Car {
 public Radio theRadio = new Radio();
 public bool isHatchBack;
}
[Serializable, XmlRoot(Namespace = "http://www.yoursite.com")]
public class JamesBondCar : Car {
 public JamesBondCar(bool SkyWorthy, bool SeaWorthy) {
 canFly = SkyWorthy;
 canSubmerge = SeaWorthy;
 }
 public JamesBondCar() { }
 [XmlAttribute]
 public bool canFly;
 [XmlAttribute]
 public bool canSubmerge;
}
class Program {
 static void Main(string[] args) {
 JamesBondCar jbc = new JamesBondCar();
 jbc.canFly = true;
 jbc.canSubmerge = false;
 jbc.theRadio.stationPresets = new double[] { 89.3, 105.1, 97.1 };
 jbc.theRadio.hasTweeters = true;
 BinaryFormatter binFormat = new BinaryFormatter();
 Stream fStream = new FileStream("CarData.dat",FileMode.Create, FileAccess.Write, FileShare.None);
 binFormat.Serialize(fStream, jbc);
 fStream.Close();
 fStream = File.OpenRead("CarData.dat");
 JamesBondCar carFromDisk =(JamesBondCar)binFormat.Deserialize(fStream);
 Console.WriteLine("Can this car fly? : {0}", carFromDisk.canFly);
 fStream.Close();
 SoapFormatter soapForamt = new SoapFormatter();
 fStream = new FileStream("CarData.soap",FileMode.Create, FileAccess.Write, FileShare.None);
 soapForamt.Serialize(fStream, jbc);
 fStream.Close();
 XmlSerializer xmlForamt = new XmlSerializer(typeof(JamesBondCar),new Type[] { typeof(Radio), typeof(Car) });
 fStream = new FileStream("CarData.xml",FileMode.Create, FileAccess.Write, FileShare.None);
 xmlForamt.Serialize(fStream, jbc);
 fStream.Close();
 ArrayList myCars = new ArrayList();
 myCars.Add(new JamesBondCar(true, true));
 myCars.Add(new JamesBondCar(true, false));
 myCars.Add(new JamesBondCar(false, true));
 myCars.Add(new JamesBondCar(false, false));
 fStream = new FileStream("CarCollection.xml",FileMode.Create, FileAccess.Write, FileShare.None);
 xmlForamt = new XmlSerializer(typeof(ArrayList),new Type[] { typeof(JamesBondCar), typeof(Car), typeof(Radio) });
 xmlForamt.Serialize(fStream, myCars);
 fStream.Close();
 }
}
