I am writing a tool to work with resume.json files (project) and am creating a Json Schema to validate user input. I'm trying to automate this with Json.Net.Schema but the output always makes all properties required, regardless of whether the properties have the [Required] or [JsonRequired] attributes.
Schema Generation Code
var generator = new JSchemaGenerator
{
ContractResolver = new CamelCasePropertyNamesContractResolver(),
SchemaIdGenerationHandling = SchemaIdGenerationHandling.TypeName
};
var schema = generator.Generate(typeof(Resume));
var sb = new StringBuilder();
schema.WriteTo(new JsonTextWriter(
new IndentedTextWriter(
new StringWriter(sb),
" ")
)
{
Formatting = Formatting.Indented,
IndentChar = ' ', Indentation = 2,
QuoteName = true
}, new JSchemaWriterSettings
{
Version = SchemaVersion.Draft7
});
File.WriteAllText("E:\\resume.schema", sb.ToString());

How do I get the schema generator to honor the Required attributes?
JSchemaGenerator has a property DefaultRequired:
Gets or sets the default required state of schemas.
For some reason, the default value for this property is Required.AllowNull, as shown in the source:
public JSchemaGenerator()
{
_schemaReferenceHandling = SchemaReferenceHandling.Objects;
_defaultRequired = Required.AllowNull;
}
If you change it to Required.Default, only those properties explicitly marked as required, e.g. with [Required] or [JsonProperty(Required = Required.Always)], will be listed as required in the schema:
var generator = new JSchemaGenerator
{
ContractResolver = new CamelCasePropertyNamesContractResolver(),
SchemaIdGenerationHandling = SchemaIdGenerationHandling.TypeName,
DefaultRequired = Required.Default,
};
The default value for DefaultRequired isn't documented, but probably should be. You might open an issue with Newtonsoft requesting a clarification to the documentation.
Demo fiddle here.
I am parsing the following JSON:
{"names":{"organizationNames":[{"name":"apple"}]}}
into the schema defined in C# Code as shown below.
public class QueryJson
{
#region Properties
[JsonProperty("organization")]
public HeOrganization Organization { get; set; }
[JsonProperty("names")]
public HeName Names { get; set; }
[JsonProperty("emails")]
public List<HeEmailAddress> Emails { get; set; }
#endregion
#region Linked Classes
public class HeOrganization
{
[JsonProperty("id")]
public Guid? ID { get; set; }
}
public class HeName
{
[JsonProperty("organizationNames")]
[Required(ErrorMessage = "Organization Name is Missing")]
public List<HeOrganizationName> OrganizationName { get; set; }
public class HeOrganizationName
{
[JsonProperty("name")]
[Required(ErrorMessage = "Name is Missing")]
public string Name { get; set; }
}
}
public class HeEmailAddress
{
[JsonProperty("address")]
[Required]
[EmailAddress]
public string Address { get; set; }
}
#endregion
}
If I were to pass an obviously invalid JSON:
{"names":{"organizationNames":[{"user":"apple"}]}}
I was expecting DeserializeObject() to fail or throw an Error, but instead it simply assigns 'Name' to null.
var myJson = JsonConvert.DeserializeObject<T>(jsonFilter);
Where T is the instance of the class.
Any suggestion on how to perform such Validations?
You could use Newtonsoft.Json.Schema to validate the schema of any given Json.
For example, for the class structure you have defined, an equivalent Schema could be generated as
var generator = new JSchemaGenerator();
var schema = generator.Generate(typeof(QueryJson));
The Generated Schema is as follows
{
"definitions": {
"HeEmailAddress": {
"type": [
"object",
"null"
],
"properties": {
"address": {
"type": "string",
"format": "email"
}
},
"required": [
"address"
]
},
"HeName": {
"type": [
"object",
"null"
],
"properties": {
"organizationNames": {
"type": "array",
"items": {
"$ref": "#/definitions/HeOrganizationName"
}
}
},
"required": [
"organizationNames"
]
},
"HeOrganization": {
"type": [
"object",
"null"
],
"properties": {
"id": {
"type": [
"string",
"null"
]
}
},
"required": [
"id"
]
},
"HeOrganizationName": {
"type": [
"object",
"null"
],
"properties": {
"name": {
"type": "string"
}
},
"required": [
"name"
]
}
},
"type": "object",
"properties": {
"organization": {
"$ref": "#/definitions/HeOrganization"
},
"names": {
"$ref": "#/definitions/HeName"
},
"emails": {
"type": [
"array",
"null"
],
"items": {
"$ref": "#/definitions/HeEmailAddress"
}
}
},
"required": [
"organization",
"names",
"emails"
]
}
You could now use the Schema to validate your jsons. For example, for the sample invalid json provided in OP
var invalidJson = #"{""names"":{""organizationNames"":[{""user"":""apple""}]}}";
var jsonInstance = JObject.Parse(invalidJson);
bool valid = jsonInstance.IsValid(schema); // False

public string username { get; set; }
}
public class Chat

public List<Entity> entities { get; set; }
}
public class Result
{
public int update_id { get; set; }
public Message message { get; set; }
}
public class RootObject
{
public bool ok { get; set; }
public List<Result> result { get; set; }
}
using newtonsoft to deserialization
var d = Newtonsoft.Json.JsonConvert.DeserializeObject(rcvd_data);
what to do next? how to put this all at work? I am confused please help.
To deserialization use this code:
RootObject ro = JsonConvert.DeserializeObject<RootObject>(rcvd_data);
And in ro you have all data.
EXAMPLE
bool ok = ro.ok;
foreach(Result r in ro.result)
{
int uId = r.update_id;
Message m = r.message;
int msgId = m.message_id;
}
string data = #"{""ok"":true,""result"":[{""update_id"":920493886,...";
RootObject ro = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(data);
foreach (Result result in ro.result)
{
//two example fields
Console.WriteLine("update_id= " + result.update_id);
Console.WriteLine("message text= "+result.message.text);
}
Based on: https://yts.am/api/v2/list_movies.json (Source: https://yts.am/api)
I used: http://json2csharp.com/ to create classes
Copy and paste the result of the get request of postman to json2csharp to automatically create the classes that you need
And once created, i used them on a Service like this:
private string URL = "https://yts.am/api/v2/list_movies.json";
public async Task<List<Movie>> GetMovies()
{
var httpClient = new HttpClient();
var json = await httpClient.GetStringAsync(URL);
RootObject lista = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json);
List<Movie> todoes = lista.data.movies;
return todoes;
}
I'm using Newtonsoft.Json
Try this way
var d = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(rcvd_data);
then d will contain list of RootObject. By iterating using foreach you can get all the properties of RootObject model
im facing a problem with probably selfreference Looping:
Model:
public class ProtectedAccount
{
public int Id { get; set; }
[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime Created { get; private set; }
public DateTime? Changed { get; set; }
public bool Disabled { get; set; }
public virtual ICollection<ProtectedAccountMember> Members { get; set; }
public virtual ProtectedAccountType Type { get; set; }
}
public class ProtectedAccountMember
{
public int Id { get; set; }
[StringLength(300)]
public string Name { get; set; }
[Index]
public virtual ProtectedAccount ProtectedAccount { get; set; }
}
Controller:
[ResponseType(typeof(ProtectedAccount))]
[Route("ProtectedAccounts/{id}/Members")]
[HttpGet]
public IHttpActionResult GetProtectedAccountMembers(int id)
{
var protectedAccount = db.ProtectedAccounts.Find(id);
if (protectedAccount == null)
{
return NotFound();
}
return Ok(protectedAccount.Members.ToList());
}
the data wich i receive for an GET seems to Loop recursive through all navigations:
[
{
"ProtectedAccount": {
"Members": [
{
"Id": 2,
"Name": "XXX, XX",
},
{
"Id": 3,
"Name": "XX, XX",
}
],
"Type": null,
"Id": 25,
"ObjectGUID": "76bf65e7-af60-4fe8-b3e1-90afbfd65b65",
"Name": "XXX",
},
"Id": 1,
"Name": "test",
},
{
"ProtectedAccount": {
"Members": [
{
"Id": 1,
"Name": "test",
},
{
"Id": 3,
"Name": "XX, XX",
"SamAccountName": "XX",
"Disabled": false
}
],
"Type": null,
"Id": 25,
"ObjectGUID": "76bf65e7-af60-4fe8-b3e1-90afbfd65b65",
"Name": "XXXX",
},
"Id": 2,
"Name": "XX, XX",
},
{
"ProtectedAccount": {a
"Members": [
{
"Id": 1,
"Name": "test",
"SamAccountName": "XXX",
"Disabled": false
},
{
"Id": 2,
"Name": "XX, XX",
"SamAccountName": "XX",
"Disabled": false
}
],
"Type": null,
"Id": 25,
"ObjectGUID": "76bf65e7-af60-4fe8-b3e1-90afbfd65b65",
"Name": "XXX",
},
"Id": 3,
"Name": "XX, XX",
}
]
There is only one "ProtectedAccount" in the database. DO i have to use DTO to overcome this issue? I tried some configuration via the json formatsettings but didnt get any better results.
From your code, you are only returing the protectedAccount.Members, hence you could do a projection query as below
var results = ctx.ProtectedAccountMembers
.Where(member => member.ProtectedAccount.Id == protectedAccount.Id)
.Select(member => new { member.Id, member.Name }).ToList();
I'm trying to deserialize a json string and I'm getting the error End element 'caption' from namespace '' expected. Found element 'created_time' from namespace ''. when calling
InstagramObject test = (InstagramObject) instagramObject.ReadObject(instagramWebResponse.GetResponseStream());
The json from Instagram returns many elements but there are only a few that I need. My DataContract will be posted below.
Basically I need {data:[{caption: string, link: string, images: {...}}]}
Here's an example of the json...
{
"data": [{
"comments": {
"data": [],
"count": 0
},
"caption": {
"created_time": "1296710352",
"text": "Inside le truc #foodtruck",
"from": {
"username": "kevin",
"full_name": "Kevin Systrom",
"type": "user",
"id": "3"
},
"id": "26621408"
},
"likes": {
"count": 15,
"data": [{
"username": "mikeyk",
"full_name": "Mike Krieger",
"id": "4",
"profile_picture": "..."
}, {...subset of likers...}]
},
"link": "http://instagr.am/p/BWrVZ/",
"user": {
"username": "kevin",
"profile_picture": "http://distillery.s3.amazonaws.com/profiles/profile_3_75sq_1295574122.jpg",
"id": "3"
},
"created_time": "1296710327",
"images": {
"low_resolution": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_6.jpg",
"width": 306,
"height": 306
},
"thumbnail": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_5.jpg",
"width": 150,
"height": 150
},
"standard_resolution": {
"url": "http://distillery.s3.amazonaws.com/media/2011/02/02/6ea7baea55774c5e81e7e3e1f6e791a7_7.jpg",
"width": 612,
"height": 612
}
},
"type": "image",
"filter": "Earlybird",
"tags": ["foodtruck"],
"id": "22721881",
"location": {
"latitude": 37.778720183610183,
"longitude": -122.3962783813477,
"id": "520640",
"street_address": "",
"name": "Le Truc"
}
}]
}
and here's my DataContract...
[DataContract]
public class InstagramObject {
[DataMember(Name = "data")]
public IEnumerable<InstagramData> instagramData { get; set; }
}
[DataContract]
public class InstagramData {
[DataMember(Name = "images")]
public List<InstagramImage> instagramImages { get; set; }
[DataMember(Name = "caption")]
public string caption { get; set; }
[DataMember(Name = "link")]
public string link { get; set; }
}
[DataContract]
public class InstagramImage {
[DataMember(Name = "low_resolution")]
public InstagramImageInfo lowResolutionImage { get; set; }
[DataMember(Name = "thumbnail")]
public InstagramImageInfo thumbnail { get; set; }
[DataMember(Name = "standard_resolution")]
public InstagramImageInfo standardResolution { get; set; }
}
[DataContract]
public class InstagramImageInfo {
[DataMember(Name = "url")]
public string url { get; set; }
[DataMember(Name = "width")]
public int width { get; set; }
[DataMember(Name = "height")]
public int height { get; set; }
}
In the data contract caption is declared as a string, but in the JSON caption is a record with various fields - caption should be declared to be an object with a compatible structure:
[DataContract]
public class InstagramCaption {
[DataMember(Name = "text")]
public string Text {get; set;}
}
. . .
[DataMember(Name = "caption")]
public InstagramCaption caption { get; set; }
. . .
No need to declare those clases If you want to go with Json.Net + Linq
var obj = (JObject)JsonConvert.DeserializeObject(json);
var result = obj["data"]
.Select(x => new {
Caption = (string)x["caption"]["text"],
Link = (string)x["link"],
Images = x["images"].Children()
.Select(y=>(string)y.First()["url"]).ToArray()
})
.ToArray();
