C# Bin、XML、Json的序列化和反序列化

1）序列化前的准备

声明类：

[Serializable]public class BandItem{//JsonIgnore：当不想把某字段值序列化到Json时使用//[JsonIgnore]public string Name { get; set; }public string MusicStyle { get; set; }public string Masterpiece { get; set; }public BandItem(string name, string musicStyle, string masterpiece){Name = name;MusicStyle = musicStyle;Masterpiece = masterpiece;}}

初始化集合：

public List<BandItem> InitList(){List<BandItem> bandList = new List<BandItem>(){new BandItem("房东的猫","民谣","下一站茶山刘"),new BandItem("Beyond","摇滚","海阔天空")};return bandList;}

2）bin 文件的序列化和反序列化

写文件（序列化）：

public void BinSerialize(List<BandItem> list){Stream stream = new FileStream("test.bin", FileMode.Create);BinaryFormatter bf = new BinaryFormatter();bf.Serialize(stream, list);stream.Close();}

读文件（反序列化）：

public List<BandItem> BinDeserialize(string filePath){Stream stream = new FileStream(filePath, FileMode.Open);BinaryFormatter bf = new BinaryFormatter();List<BandItem> list = (List<BandItem>)bf.Deserialize(stream);stream.Close();return list;}

3）XML 的序列化和反序列化

序列化为 XML：

public string XMLSerialize(List<BandItem> list){System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(list.GetType());StringWriter sw = new StringWriter();x.Serialize(sw, list);string xml = sw.ToString();return xml;}

XML反序列化：

public List<BandItem> XMLDeserialize(string xml){System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(typeof(List<BandItem>));StringReader sr = new StringReader(xml);var list = (List<BandItem>)x.Deserialize(sr);return list;}

4）Json 的序列化和反序列化

需要一个程序包，在程序包管理控制台里输入安装命令：Install-Package Newtonsoft.Json

序列化为Json：

public string JsonSerialize(List<BandItem> list){string json = JsonConvert.SerializeObject(list);return json;}

Json反序列化：

public List<BandItem> JsonDeserialize(string json){List<BandItem> list = JsonConvert.DeserializeObject<List<BandItem>>(json);return list;}

5）序列化转换的模板

统一集合里的类型，编写成一个模板：

//对序列化和反序列化的处理public static class SerializeConver{//Bin文件的序列化public static bool BinSerializable<T>(T list,string newFilePath){try{Stream stream = new FileStream(newFilePath, FileMode.Create);BinaryFormatter bf = new BinaryFormatter();bf.Serialize(stream, list);stream.Close();return true;}catch(Exception ex){return false;}}//Bin文件的反序列化public static T BinDeserialize<T>(string sourceFilePath){Stream stream = new FileStream(sourceFilePath, FileMode.Open);BinaryFormatter bf = new BinaryFormatter();T list = (T)bf.Deserialize(stream);stream.Close();return list;}//可扩展其他格式的序列化和反序列模板...}

模板的使用：

var list = InitList();var isSerial = SerializeConver.BinSerializable<List<BandItem>>(list,"test.bin");var readList = SerializeConver.BinDeserialize<List<BandItem>>("test.bin");
