如何获取对象并将其转换为JSON字符串,然后从字符串返回到该对象,特别是在WinRT中为我的Windows 8 Metro应用程序?
Like this:
using System.IO;
using System.Runtime.Serialization.Json;
using System.Text;
public static T Deserialize<T>(string json)
{
var _Bytes = Encoding.Unicode.GetBytes(json);
using (MemoryStream _Stream = new MemoryStream(_Bytes))
{
var _Serializer = new DataContractJsonSerializer(typeof(T));
return (T)_Serializer.ReadObject(_Stream);
}
}
public static string Serialize(object instance)
{
using (MemoryStream _Stream = new MemoryStream())
{
var _Serializer = new DataContractJsonSerializer(instance.GetType());
_Serializer.WriteObject(_Stream, instance);
_Stream.Position = 0;
using (StreamReader _Reader = new StreamReader(_Stream))
{ return _Reader.ReadToEnd(); }
}
}
First generate C# classes with http://json2csharp.com/ Then use http://james.newtonking.com/pages/json-net.aspx for parsing
My user class currently looks like this:
public class User
{
public string id { get; set; }
public string username { get; set; }
public string full_name { get; set; }
public string profile_picture { get; set; }
public string bio { get; set; }
public string website { get; set; }
public Counts counts { get; set; }
public static User SingleFromJSON(string jsonString)
{
return JsonConvert.DeserializeObject<SingleUser>(jsonString).data;
}
public static User MultipleFromJSON(string jsonString)
{
return JsonConvert.DeserializeObject<SingleUser>(jsonString).data;
}
private class SingleUser
{
public User data { get; set; }
}
private class MultipleUsers
{
public List<User> data { get; set; }
}
}
public class Counts
{
public int media { get; set; }
public int follows { get; set; }
public int followed_by { get; set; }
}
Super easy :D
OP asked for an answer that pertained to metro apps on Windows 8, but this question comes up when doing a basic search for serializing/de-serializing jsons for WinRT, so I'm adding this answer for those who are looking for a more modern approach.
Modern WinRT has built-in handlers for this challenge, so no need to use JSON.net
Use JsonObject
from Windows.Data.Json
For serializing use Parse
or TryParse
.
For de-serializing but still in JSON format, use Stringify
.
