Cómo se analiza un archivo JSON utilizando JSON.net

Question

Estoy intentando leer un archivo JSON y analizarlo. Tengo este código para la lectura de mi archivo

StreamReader re = new StreamReader("artists.json"); 
JsonTextReader reader = new JsonTextReader(re); 

Pero ¿cómo puedo analizarlo ahora de lector para que pueda buscar los datos en el archivo?

he intentado leer el documentation pero no hemos podido encontrar nada

Answer 1

using Newtonsoft.Json; 

    //.. 

    JsonSerializer se = new JsonSerializer(); 
    object parsedData = se.Deserialize(reader);

en respuesta a "Algunos detalles sobre cómo implementar esto sería útil -. Aknatn"

using Newtonsoft.Json; 
using System; 
using System.Collections.Generic; 
using System.IO; 
using System.Text; 

public class Program 
    { 
     public static void Main() 
     { 
      //JSON = {"Property1":"as","CollectionProperty":[{"prop1":"1","prop2":"2","prop3":"3"}]} 

      //This Top part is just to build a stream 
      //- No need to do this if you are accessing a file 
      string JSON = "{\"Property1\":\"SomePropName\",\"CollectionProperty\":"+ 
      "[{\"prop1\":\"1\",\"prop2\":\"2\",\"prop3\":\"3\"}]}"; 
      byte[] byteArray = Encoding.UTF8.GetBytes(JSON); 
      //byte[] byteArray = Encoding.ASCII.GetBytes(contents); 
      MemoryStream stream = new MemoryStream(byteArray); 
      // convert stream to string 

      JsonSerializer se = new JsonSerializer(); 

      StreamReader re = new StreamReader(stream); 
      JsonTextReader reader = new JsonTextReader(re); 
      var DeserializedObject = se.Deserialize<Collections>(reader); 

      Console.WriteLine(DeserializeObject.Property1); 

      //"...so I can search data from the file?" 
      //This is up to you and how you wanna handle it, but you now have JSON 
      //Deserialized and stored in memory. 'How to search' depends on objects class 
      //Also, Original question said he had the JSON. I would recommend using 
      //json2csharp.com/ or jsonutils.com/ 
      //to retrieve the classes in order to Deserialize it to your object. 

      //Note 1: You don't always have to cast it 
      //- I just always try to if and when I can 
      //Note 2: Because you are using a StreamReader, 
      //this will account for Large JSON Objects 
     } 


    public class Collections 
    { 
     public List<CollectionProperty> CollectionProperty = new List<CollectionProperty>(); 
     public string Property1; 
    } 

    public class CollectionProperty 
    { 
     public string prop1 { get; set; } 
     public string prop2 { get; set; } 
     public string prop3 { get; set; } 
    } 
    } 

Answer 3

Si desea para cargarlo en un JObject o tipo dinámico (y no deserializarlo en un tipo .NET), puede usar el JObject.Load método

using(var sr = new StreamReader("artists.json")) 
{ 
    var reader = new JsonTextReader(sr); 
    var jObject = JObject.Load(reader); 

    //Get property from JObject 
    var someValue = jObject.GetValue("someProperty").Value<string>(); 

    // JObject can be cast into a dynamic 
    var dObject = (dynamic)jObject; 
    someValue = (string)dObject.someProperty; 

}
