Json.net

json.netはC〓で書いたJsonの操作類型の倉庫です。http://json.codeplex.com/ ダウンロード
オブジェクトの順序をjson文字列にします。

public class Product
{
    public string Name { get; set; }
    public DateTime Expiry { get; set; }
    public decimal Price { get; set;}
    public string[] Sizes { get; set; }
}

static void Main(string[] args)
{
    Product product = new Product() { 
       Name ="android",
       Expiry =new DateTime (),
       Price =2000,
       Sizes =new  string[]{"1.5","2.2","4.1"}
    };

    Console.WriteLine(JsonConvert.SerializeObject(product));

    Console.Read();
}

出力:

{"Name":"android","Expiry":"\/Date(-62135596800000 0800)\/","Price":2000.0,"Size
s":["1.5","2.2","4.1"]}

 
時間タイプの書式を設定します。2つのオブジェクトをプログレッシブ時間の対象として使用します。IsoDateTimeConter JavaScript DateTimeConverter。

Console.WriteLine(JsonConvert .SerializeObject (product,new IsoDateTimeConverter()));

Console.WriteLine(JsonConvert.SerializeObject(product, new JavaScriptDateTimeConverter()));

出力

{"Name":"android","Expiry":"2000-09-09T00:00:00","Price":2000.0,"Sizes":["1.5","
2.2","4.1"]}
{"Name":"android","Expiry":new Date(968428800000),"Price":2000.0,"Sizes":["1.5",
"2.2","4.1"]}

カスタム出力時間書式

IsoDateTimeConverter iso = new IsoDateTimeConverter();
 iso.DateTimeFormat = "yyyy-MM-dd";//       

Console.WriteLine(JsonConvert.SerializeObject(product, iso));

出力

{"Name":"android","Expiry":"2000-09-09","Price":2000.0,"Sizes":["1.5","2.2","4.1
"]}

反プロローグ

Product p=(Product)JsonConvert.DeserializeObject(str, typeof(Product));

Jobjectオブジェクトを作成

JObject rss =
  new JObject(
    new JProperty("channel",
      new JObject(
        new JProperty("title", "James Newton-King"),
        new JProperty("link", "http://james.newtonking.com"),
        new JProperty("description", "James Newton-King's blog."),
        new JProperty("item",
          new JArray(
            from p in posts
            orderby p.Title
            select new JObject(
              new JProperty("title", p.Title),
              new JProperty("description", p.Description),
              new JProperty("link", p.Link),
              new JProperty("category",
                new JArray(
                  from c in p.Categories
                  select new JValue(c)))))))));
 
Console.WriteLine(rss.ToString());

オブジェクトを直接使用してJobjectオブジェクトを作成します。

JObject obj = JObject.FromObject(new Product()
             {
                 Name = "android",
                 Expiry = new DateTime(2000, 9, 9),
                 Price = 2000,
                 Sizes = new string[] { "1.5", "2.2", "4.1" }
             });
