json数据解析转文本方法

Posted 2021-01-13 扎北强子

需要用到LitJSON.dll

JsonMapper

using LitJson;

using System;

 

public class Person

{

    // C# 3.0 auto-implemented properties

    public string   Name     { get; set; }

    public int      Age      { get; set; }

    public DateTime Birthday { get; set; }

}

 

public class JsonSample

{

    public static void Main()

    {

        PersonToJson();

        JsonToPerson();

    }

 

    public static void PersonToJson()

    {

        Person bill = new Person();

 

        bill.Name = "William Shakespeare";

        bill.Age  = 51;

        bill.Birthday = new DateTime(1564, 4, 26);

 

        string json_bill = JsonMapper.ToJson(bill);

 

        Console.WriteLine(json_bill);

    }

 

    public static void JsonToPerson()

    {

        string json = @"

            {

                ""Name""     : ""Thomas More"",

                ""Age""      : 57,

                ""Birthday"" : ""02/07/1478 00:00:00""

            }";

 

        Person thomas = JsonMapper.ToObject<Person>(json);

 

        Console.WriteLine("Thomas‘ age: {0}", thomas.Age);

    }

}

JsonMapper.ToObject

using LitJson;

using System;

 

public class JsonSample

{

    public static void Main()

    {

        string json = @"

          {

            ""album"" : {

              ""name""   : ""The Dark Side of the Moon"",

              ""artist"" : ""Pink Floyd"",

              ""year""   : 1973,

              ""tracks"" : [

                ""Speak To Me"",

                ""Breathe"",

                ""On The Run""

              ]

            }

          }

        ";

 

        LoadAlbumData(json);

    }

 

    public static void LoadAlbumData(string json_text)

    {

        Console.WriteLine("Reading data from the following JSON string: {0}",

                          json_text);

 

        JsonData data = JsonMapper.ToObject(json_text);

 

        // Dictionaries are accessed like a hash-table

        Console.WriteLine("Album‘s name: {0}", data["album"]["name"]);

 

        // Scalar elements stored in a JsonData instance can be cast to

        // their natural types

        string artist = (string) data["album"]["artist"];

        int    year   = (int) data["album"]["year"];

 

        Console.WriteLine("Recorded by {0} in {1}", artist, year);

 

        // Arrays are accessed like regular lists as well

        Console.WriteLine("First track: {0}", data["album"]["tracks"][0]);

    }

}

JsonReader

using LitJson;

using System;

 

public class DataReader

{

    public static void Main()

    {

        string sample = @"{

            ""name""  : ""Bill"",

            ""age""   : 32,

            ""awake"" : true,

            ""n""     : 1994.0226,

            ""note""  : [ ""life"", ""is"", ""but"", ""a"", ""dream"" ]

          }";

 

        PrintJson(sample);

    }

 

    public static void PrintJson(string json)

    {

        JsonReader reader = new JsonReader(json);

 

        Console.WriteLine ("{0,14} {1,10} {2,16}", "Token", "Value", "Type");

        Console.WriteLine (new String (‘-‘, 42));

 

        // The Read() method returns false when there‘s nothing else to read

        while (reader.Read()) {

            string type = reader.Value != null ?

                reader.Value.GetType().ToString() : "";

 

            Console.WriteLine("{0,14} {1,10} {2,16}",

                              reader.Token, reader.Value, type);

        }

    }

}
