gama Deserialize JSON (o lista) en C#

Question

aquí es el código básico:

public static string DeserializeNames() 
{ 

    jsonData = "{\"name\":[{\"last\":\"Smith\"},{\"last\":\"Doe\"}]}"; 

    JavaScriptSerializer ser = new JavaScriptSerializer(); 

    nameList myNames = ser.Deserialize<nameList>(jsonData); 

    return ser.Serialize(myNames); 
} 

//Class descriptions 

public class name 
{ 

    public string last { get; set; } 

} 

public class nameList 
{ 

    public List<name> { get; set; } 

} 

que he intentado:

nameList myNames = ser.Deserialize<nameList>(jsonData); 

y:

List<name> myNames = ser.Deserialize<List<name>>(jsonData); 

y ni trabajo. ¿Alguien tiene alguna idea?

Answer 1

Este código funciona para mí:

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Web.Script.Serialization; 

namespace Json 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      Console.WriteLine(DeserializeNames()); 
      Console.ReadLine(); 
     } 

     public static string DeserializeNames() 
     { 
      var jsonData = "{\"name\":[{\"last\":\"Smith\"},{\"last\":\"Doe\"}]}"; 

      JavaScriptSerializer ser = new JavaScriptSerializer(); 

      nameList myNames = ser.Deserialize<nameList>(jsonData); 

      return ser.Serialize(myNames); 
     } 

     //Class descriptions 

     public class name 
     { 
      public string last { get; set; } 
     } 

     public class nameList 
     { 
      public List<name> name { get; set; } 
     } 
    } 
} 

Answer 2

Descargar Json.NET de aquí http://james.newtonking.com/projects/json-net.aspx

name deserializedName = JsonConvert.DeserializeObject<name>(jsonData); 

Answer 3

que estaba teniendo el problema similar y se resuelven mediante la comprensión de las clases en asp.net C#

Quiero leer la siguiente cadena JSON:

      } 
     ], 
     "resultSize": 1171, 
     "pageIndex": "1" 
    }

A continuación, la página del explorador que lee la cadena/Cadena JSON enumerados arriba y muestra/Deserializar los objetos JSON y muestra los datos

JavaScriptSerializer ser = new JavaScriptSerializer(); 


     string final_sb = sb.ToString(); 

     List<Class3.ListWrapper_Main> movieInfos = ser.Deserialize<List<Class3.ListWrapper_Main>>(final_sb.ToString()); 

     foreach (var itemdetail in movieInfos) 
     { 

      foreach (var itemdetail2 in itemdetail.ResultList) 
      { 
       Response.Write("channelType=" + itemdetail2.channelType + "<br/>"); 
       Response.Write("duration=" + itemdetail2.duration + "<br/>"); 
       Response.Write("episodeno=" + itemdetail2.episodeno + "<br/>"); 
       Response.Write("genre=" + itemdetail2.genre + "<br/>"); 

       string[] genreList_arr = itemdetail2.genreList; 
       for (int i = 0; i < genreList_arr.Length; i++) 
        Response.Write("genreList1=" + genreList_arr[i].ToString() + "<br>"); 

       foreach (var genres1 in itemdetail2.genres) 
       { 
        Response.Write("genres1=" + genres1.personName + "<br>"); 
       } 

       Response.Write("id=" + itemdetail2.id + "<br/>"); 
       Response.Write("imageUrl=" + itemdetail2.imageUrl + "<br/>"); 
       //Response.Write("imageurl=" + itemdetail2.imageurl + "<br/>");

       //Response.Write("resultSize" + itemdetail2.resultSize + "<br/>"); 
       // Response.Write("pageIndex" + itemdetail2.pageIndex + "<br/>"); 


      } 



      Response.Write("resultSize=" + itemdetail.resultSize + "<br/><br>"); 
      Response.Write("pageIndex=" + itemdetail.pageIndex + "<br/><br>"); 

     } 

'sb' es la cadena real, es decir, cadena JSON de datos mencionada primera en la parte superior de esta respuesta

Esto es básicamente - aplicación web asp.net C# código ....

N alegría ..
