newtonsoft.com: json.


// Serialize JSON

Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Sizes = new string[] { "Small" };

string json = JsonConvert.SerializeObject(product);
// {
//   "Name": "Apple",
//   "Expiry": "2008-12-28T00:00:00",
//   "Sizes": [
//     "Small"
//   ]
// }

// Deserialize JSON

string json = @"{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
    'Action',
    'Comedy'
  ]
}";

Movie m = JsonConvert.DeserializeObject<Movie>(json);

string name = m.Name;
// Bad Boys

// LINQ to JSON

JArray array = new JArray();
array.Add("Manual text");
array.Add(new DateTime(2000, 5, 23));

JObject o = new JObject();
o["MyArray"] = array;

string json = o.ToString();
// {
//   "MyArray": [
//     "Manual text",
//     "2000-05-23T00:00:00"
//   ]
// }

newtonsoft.com: json example: deserializeAnonymouseType.


var definition = new { Name = "" };

string json1 = @"{'Name':'James'}";
var customer1 = JsonConvert.DeserializeAnonymousType(json1, definition);

Console.WriteLine(customer1.Name);
// James

string json2 = @"{'Name':'Mike'}";
var customer2 = JsonConvert.DeserializeAnonymousType(json2, definition);

Console.WriteLine(customer2.Name);
// Mike

//////////////////// Validate JSON

JSchema schema = JSchema.Parse(@"{
  'type': 'object',
  'properties': {
    'name': {'type':'string'},
    'roles': {'type': 'array'}
  }
}");

JObject user = JObject.Parse(@"{
  'name': 'Arnie Admin',
  'roles': ['Developer', 'Administrator']
}");

bool valid = user.IsValid(schema);
// true

//////////////////// Generate Schemas

JSchemaGenerator generator = new JSchemaGenerator();
JSchema schema = generator.Generate(typeof(Account));
// {
//   "type": "object",
//   "properties": {
//     "email": { "type": "string", "format": "email" }
//   },
//   "required": [ "email" ]
// }

public class Account
{
    [EmailAddress]
    [JsonProperty("email", Required = Required.Always)]
    public string Email;
}

//////////////////// Validate Deserialization

JSchema schema = JsonSchema.Parse(@"{
  'type': 'array',
  'item': {'type':'string'}
}");
JsonTextReader reader = new JsonTextReader(new StringReader(@"[
  'Developer',
  'Administrator'
]"));

JSchemaValidatingReader validatingReader = new JSchemaValidatingReader(reader);
validatingReader.Schema = schema;

JsonSerializer serializer = new JsonSerializer();
List<string> roles = serializer.Deserialize<List<string>>(validatingReader);
