C# Bin、XML、Json的序列化和反序列化

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;
        }

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;
        }

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;
        }

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;
        }

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");
