I am using json for the first time and after a search in the internet I found JSON.NET. I thought it is easy to use but I have a problem with it. Every time i use the code i get a warning:
Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'JSON_WEB_API.Machine' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
This is the JSON array from the URL:
[
{
"id": "MachineTool 1",
"guid": "not implemented",
"name": "Individueller Maschinenname",
},
{
"id": "MachineTool 2",
"guid": "not implemented",
"name": "Individueller Maschinenname",
}
]
And this is the CODE:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.Runtime.Serialization;
using Newtonsoft.Json;
namespace JSON_WEB_API
{
class Program
{
static void Main()
{
string json = new WebClient().DownloadString("http://localhost:12084/Machines?format=json");
Console.WriteLine(json);
//string json = @"[{"id":"MachineTool 1","guid":"not implemented","name":"Individueller Maschinenname"},{"id":"MachineTool 2","guid":"not implemented","name":"Individueller Maschinenname"}]
//Console.WriteLine(json)";
Machine machine = JsonConvert.DeserializeObject<Machine>(json);
Console.WriteLine(machine.id);
Console.Read();
}
}
[DataContract]
class Machine
{
[DataMember]
internal string id { get; set; }
[DataMember]
internal string guid { get; set; }
[DataMember]
internal string name { get; set; }
}
}
convert it to list of Machine
var machine = JsonConvert.DeserializeObject<List<Machine>>(json);
To Access the Data run the foreach on machine.
foreach(var data in machine )
{
Console.WriteLine(data.id);
}
