Jil,高效的json序列化和反序列化庫(kù)

下面小編就為大家?guī)?lái)一篇Jil,高效的json序列化和反序列化庫(kù)。小編覺(jué)得挺不錯(cuò)的，現(xiàn)在就分享給大家，也給大家做個(gè)參考。一起跟隨小編過(guò)來(lái)看看吧

谷歌的potobuf不說(shuō)了，它很牛B，但是對(duì)客戶端對(duì)象不支持，比如JavaScript就讀取不了。

Jil很牛，比Newtonsoft.Json要快很多，且支持客戶端，此處只貼代碼：

using Jil;
using System.Runtime.Serialization;

[Serializable]
 class Employee
 {
  //[JilDirective(Name = "cid")]
  public int Id { get; set; }
  [IgnoreDataMember]
  public string Name { get; set; }
  [DataMember(Name = "kkl")]
  public string Address { get; set; }
 
  public Employee() { } //必須要有一個(gè)午餐的構(gòu)造函數(shù)

  public Employee(int EmployeeId, string Name)
  {
  this.Id = EmployeeId;
  this.Name = Name;
  }
 }var jsonString = string.Empty;
  using (var output = new StringWriter())
  {
  JSON.Serialize(new Employee(666, "zhangsan"), output);
  Console.WriteLine(output);
  jsonString = output.ToString();
  }

  using (var input = new StringReader(jsonString))
  {
  //var result = JSON.DeserializeDynamic(jsonString);
  //var result = JSON.Deserialize<Employee>(jsonString);
  var result = JSON.Deserialize<Employee>(input);
  Console.WriteLine("id:{0},name:{1}", result.Id, result.Name);
  }

需要注意的是，反序列化的強(qiáng)類型對(duì)象必須要有無(wú)參的構(gòu)造函數(shù)或者只有一個(gè)參數(shù)的構(gòu)造函數(shù)。

Such a type should have one declared field or property, and default or single parameter constructor.

對(duì)于時(shí)間處理，默認(rèn)是ISO8601方式，可通過(guò)配置修改：

Options _jilOptions = new Options(
  dateFormat: DateTimeFormat.MillisecondsSinceUnixEpoch,
  includeInherited: true,
  serializationNameFormat: SerializationNameFormat.CamelCase
  );

  var output = JSON.Serialize(new
  {
  UserName = "jon",
  TradingPassword = "123456",
  ClientIp = "192.168.3.1",
  Origin = 1,
  time = DateTime.Now
  }, _jilOptions);
  Console.WriteLine(output);

  Console.WriteLine("----------------");

  var pt = "1459481266695"; //時(shí)間戳
  DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));
  //說(shuō)明下，時(shí)間格式為13位后面補(bǔ)加4個(gè)"0"，如果時(shí)間格式為10位則后面補(bǔ)加7個(gè)"0" 
  long lTime = long.Parse(pt + (pt.Length == 13 ? "0000" : "0000000"));
  var dtResult = dtStart.Add(new TimeSpan(lTime)); //得到轉(zhuǎn)換后的時(shí)間 
  Console.WriteLine(dtResult);

  Console.WriteLine("----------------");

  var _time = DateTime.Now.Ticks;
  Console.WriteLine(DateTime.Now.ToString());
  Console.WriteLine("當(dāng)前時(shí)間轉(zhuǎn)換后模式：---------------->");
  var dt = DateTime.FromBinary(_time); //635951023596206937【注意，此處與】
  Console.WriteLine(dt.ToLongDateString()); //2016年4月1日
  Console.WriteLine(dt.ToLongTimeString()); //10:12:39
  Console.WriteLine(dt.ToShortDateString()); //2016/4/1
  Console.WriteLine(dt.ToShortTimeString()); //10:12
  Console.WriteLine(dt.ToString("yyyy-MM-dd HH:mm:ss")); //2016-04-01 10:12:39

輸入如下：

關(guān)于客戶端時(shí)間戳的js處理，可參閱此文：js時(shí)間戳和c#時(shí)間戳互轉(zhuǎn)方法(推薦)

var date = new Date(1459481266695);
Y = date.getFullYear() + '-';
M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1) + '-';
D = date.getDate() + ' ';
h = date.getHours() + ':';
m = date.getMinutes() + ':';
s = date.getSeconds(); 
console.log(Y+M+D+h+m+s);
