I've got a question. I try to get value from JSON. JSON have been sent from server by socket. In Client I've got sth like this:
string data = null;
// Receive the response from the remote device.
int bytesRec = sender.Receive(bytes);
data += Encoding.ASCII.GetString(bytes, 0, bytesRec);
Console.WriteLine(data);
Console.ReadLine();
And in console I see :
{"player":0, "size":3}
How can I get value from this String ?
it is very simple. first download this nuget via Package Manager Console:
Install-Package Newtonsoft.Json -Version 11.0.2
then add this namespace: Newtonsoft.Json.Linq
JObject jObject = JObject.Parse(data);
int player = jObject["player"].Value<int>();
The easiest way to do this is to use Visual Studio: Copy the JSON text into the clipboard then select Edit | Paste Special | Paste JSON as classes. Rename the class as desired (for this example, call it Demo).
Newtonsoft.JsonDemo result = JsonConvert.DeserializeObject<Demo>("{\"player\":0, \"size\":3}");Example console app:
using System;
using Newtonsoft.Json;
namespace Demo
{
public class Demo
{
public int player { get; set; }
public int size { get; set; }
}
class Program
{
static void Main()
{
Demo result = JsonConvert.DeserializeObject<Demo>("{\"player\":0, \"size\":3}");
Console.WriteLine(result.player); // "0"
Console.WriteLine(result.size); // "3"
}
}
}
You could create a class:
public class MyObject
{
public int Player {get; set;}
public int Size {get; set;}
}
And then deserialize the JSON string using something like JSON.NET:
MyClass myClassObject = JsonConvert.DeserializeObject<MyObject>(data);
var playerId = myClassObject.Player;
Add the Nuget package for JSON.net:
In the Nuget Package Manager search for "Newtonsoft.Json".
Or use the console:
Install-Package Newtonsoft.Json
Once installed you can use the following code for an anonymous type:
using Newtonsoft.Json;
var anonymousTypeDefinition = new { player = -1, size = -1 };
var player = JsonConvert.DeserializeAnonymousType(data, anonymousTypeDefinition);
Or you can use the following code for a strong type:
public class Player
{
int Size { get; set; }
int Player { get; set; }
}
// in the console
var player = Newtonsoft.Json.JsonConvert.DeserializeObject<Player>(data);
{"player":0 "size":3}is not valid JSON, it should be{"player":0, "size":3}
