I have got following JSON that should be deserialized to C# class:
{"status":"error","messages":[{"level":"error","key":"InvalidTokenError","dsc":"Invalid
token"}]}
So I have a questions what is the kind of type should be
[{"level":"error","key":"InvalidTokenError","dsc":"Invalid token"}]
?
Is this array, list or class?
You can use json2csharp.com to get the types of the JSON.
JSON:
{"status":"error","messages":[{"level":"error","key":"InvalidTokenError","dsc":"Invalid token"}]}
Here is the classes generated for your JSON:
public class Message
{
public string level { get; set; }
public string key { get; set; }
public string dsc { get; set; }
}
public class RootObject
{
public string status { get; set; }
public List<Message> messages { get; set; }
}
for JSON:
[{"level":"error","key":"InvalidTokenError","dsc":"Invalid token"}]
Type:
public class Message
{
public string level { get; set; }
public string key { get; set; }
public string dsc { get; set; }
}
You can use this site
public class Message
{
public string level { get; set; }
public string key { get; set; }
public string dsc { get; set; }
}
public class RootObject
{
public string status { get; set; }
public List<Message> messages { get; set; }
}

I currently have JSON coming in as follows:
{"36879":[{"min_qty":1,"discount_type":"%","csp_price":10}],"57950":[{"min_qty":1,"discount_type":"flat","csp_price":650}]}
This contains a list of the following records
ProductId
MinQty
DiscountType
Price
I need to deserialize this into the following model:
public class CustomerSpecificPricing
{
string productId { get; set; }
public virtual List<CustomerSpecificPricingDetail> CustomerSpecificPricingDetails { get; set; }
}
public class CustomerSpecificPricingDetail
{
public string min_qty { get; set; }
public string discount_type { get; set; }
public string csp_price { get; set; }
}
The problem is that the "productId" of each record is missing the key name.
If I run my JSON through J2C, I get the following:
public class 36879 {
public int min_qty { get; set; }
public string discount_type { get; set; }
public int csp_price { get; set; }
}
public class 57950 {
public int min_qty { get; set; }
public string discount_type { get; set; }
public int csp_price { get; set; }
}
public class Root {
public List<_36879> _36879 { get; set; }
public List<_57950> _57950 { get; set; }
}
Which is obviously incorrect.
How would I deserialize my object correctly?
You would need to deserialize it into a dictionary first and then map it into the format you require after. Something like this should work:
var dict = JsonConvert.DeserializeObject<Dictionary<string, IEnumerable<CustomerSpecificPricingDetail>>>();
var result = dict.Select(kvp => new CustomerSpecificPricing { ProductId = Int32.Parse(kvp.Key), CustomerSpecificPricingDetails = kvp.Value });
Id also recommend you follow the conventional standards of naming. In this case properties in classes should be PascalCase,
e.g. your classes now become:
public class CustomerSpecificPricing
{
[JsonProperty("productId ")]
public string ProductId { get; set; }
public virtual List<CustomerSpecificPricingDetail> CustomerSpecificPricingDetails { get; set; }
}
and
public class CustomerSpecificPricingDetail
{
[JsonProperty("min_qty")]
public string MinQty { get; set; }
[JsonProperty("discount_type ")]
public string DiscountType { get; set; }
[JsonProperty("csp_price ")]
public string CspPrice { get; set; }
}
I'm having problems deserializing the data I'm getting from Shodan. Below are the classes I got from json2csharp and I'm trying to create an array of the matches and loop through them. It seems like I have tried with everything except a working array by now. The data itself is matches as root with objects of them that contain location (with its own data etc). An except below that I cut out a bit.
This is my error:
Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'Shodan.Match[]' because the type requ
ires a JSON array (e.g. [1,2,3]) to deserialize correctly.
var data = JsonConvert.DeserializeObject<Match[]>(allData);
{"matches": [{"product": "product", "hash": 0, "ip": 123123, "isp": "Verizon Internet Services"}], "total": 1}
public class Location
{
public string city { get; set; }
public string region_code { get; set; }
public object area_code { get; set; }
public double longitude { get; set; }
public string country_code3 { get; set; }
public double latitude { get; set; }
public string postal_code { get; set; }
public object dma_code { get; set; }
public string country_code { get; set; }
public string country_name { get; set; }
}
public class Options
{
}
public class Shodan
{
public string crawler { get; set; }
public string id { get; set; }
public string module { get; set; }
public Options options { get; set; }
}
public class Match
{
public int hash { get; set; }
public int ip { get; set; }
public string isp { get; set; }
public string transport { get; set; }
public string data { get; set; }
public string asn { get; set; }
public int port { get; set; }
public List<string> hostnames { get; set; }
public Location location { get; set; }
public DateTime timestamp { get; set; }
public List<string> domains { get; set; }
public string org { get; set; }
public object os { get; set; }
public Shodan _shodan { get; set; }
public string ip_str { get; set; }
public string product { get; set; }
}
public class RootObject
{
public List<Match> matches { get; set; }
public int total { get; set; }
}
You could create another class like
var allData =
{"matches": [{"product": "product", "hash": 0, "ip": 123123, "isp": "Verizon Internet Services"}], "total": 1}
public class MyMatches {
public Match[] matches {get; set;}
}
and then use that in the deserializer.
var data = JsonConvert.DeserializeObject<MyMatches>(allData);
This is if the JSON code sample you gave us is correct.
CORRECTION
Just saw the RootObject class.
Just use that.
My JSON file
[
{
"amount":"1000000.0",
"check_number":1,
"payment_number":5,
"attachments":[
{
"id":5324,
"url":"http://www.example.com/",
"filename":"january_receipt_copy.jpg"
}
]
}
]
My Class File
public class Attachment
{
public int id { get; set; }
public string url { get; set; }
public string filename { get; set; }
}
public class AccountDetail
{
public string amount { get; set; }
public int check_number { get; set; }
public int payment_number { get; set; }
}
public class RootObject
{
public AccountDetail accountdetail{ get; set; }
public List<Attachment> attachments { get; set; }
}
Now I want to map JSON file's properties 'check_number','amount' etc
to accountdetail by using newtonsoft JSON deserialization.
You need the following two classes:
public class Attachment
{
[JsonProperty("id")]
public int Id { get; set; }
[JsonProperty("url")]
public string Url { get; set; }
[JsonProperty("filename")]
public string Filename { get; set; }
}
public class AccountDetails
{
[JsonProperty("amount")]
public string Amount { get; set; }
[JsonProperty("check_number")]
public int CheckNumber { get; set; }
[JsonProperty("payment_number")]
public int PaymentNumber { get; set; }
[JsonProperty("attachments")]
public IList<Attachment> Attachments { get; set; }
}
By defining the above classes you can deserialize your json as below:
var accountsDetails = JsonConvert.DeserializeObject<IEnumerable<AccountDetails>>(json);
I have a JSON request which has follwing structure:
"formats": {
"flash_embed": "http://a3.vikiassets.com/assets/vikiplayer-922746a667cfd38137a7e45df6ba1b95.swf?auto_play=true&language_codes=en&media_id=74965&partner=16&source=api_v3",
"m3u8": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965/ios.m3u8",
"res-150p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_mp4cell_150.mp4",
"res-240p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_240p.mp4",
"res-270p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_270p.mp4",
"res-360p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_360p.mp4",
"res-480p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_480p.mp4",
"res-720p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_720p.mp4"
}
}
Now res-150p, says invalid name in C# and if I give another name to it then while desiralizing I am not getting any values, that is null inside res-150p.
Edit:
[Serializable]
MoviesListRootObject is the root Object which Contains Response and then Response Contains Formats
public class MoviesListRootObject
{
public int count { get; set; }
public Pagination pagination { get; set; }
public List<Response> response { get; set; }
}
[Serializable]
public class Response
{
public int id { get; set; }
public int channel_id { get; set; }
public string title { get; set; }
public string title_language { get; set; }
public string description { get; set; }
public string description_language { get; set; }
public string created_at { get; set; }
public string uri { get; set; }
public string web_uri { get; set; }
public List<object> genres { get; set; }
public string origin_country { get; set; }
public string image { get; set; }
public Subtitles subtitles { get; set; }
public Formats formats { get; set; }
}
[Serializable]
public class Formats
{
public string flash_embed { get; set; }
public string m3u8 { get; set; }
public string __invalid_name__res150p { get; set; }
public string __invalid_name__res240p { get; set; }
public string __invalid_name__res270p { get; set; }
public string __invalid_name__res360p { get; set; }
public string __invalid_name__res480p { get; set; }
public string __invalid_name__res720p { get; set; }
public string __invalid_name__flv480p { get; set; }
public string __invalid_name__flv360p { get; set; }
public string __invalid_name__flv270p { get; set; }
public string __invalid_name__flvvp6360p { get; set; }
public string __invalid_name__flvvp6270p { get; set; }
}
You have to decorate your Formats properties with JsonProperty attributes to tell it what goes where if the name does not exactly match:
partial class Formats
{
[JsonProperty("res-150p")]
public string __invalid_name__res150p {get; set;}
}

I have this specific JSON response that I am trying to deserialize without success. I am hoping someone can help me.
Here is the JSON response I get:
{
"num_locations": 1,
"locations": {
"98765": {
"street1": "123 Fake Street",
"street2": "",
"city": "Lawrence",
"state": "Kansas",
"postal_code": "66044",
"s_status": "20",
"system_state": "Off"
}
}
}
I used json2csharp http://json2csharp.com and got these recommended classes:
public class __invalid_type__98765
{
public string street1 { get; set; }
public string street2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postal_code { get; set; }
public string s_status { get; set; }
public string system_state { get; set; }
}
public class Locations
{
public __invalid_type__98765 __invalid_name__98765 { get; set; }
}
public class RootObject
{
public int num_locations { get; set; }
public Locations locations { get; set; }
}
But when I try to use it in my code:
var locationResponse = JsonConvert.DeserializeObject<RootObject>(response.Content);
What I get is (Watch):
locationResponse : {RestSharpConsoleApplication.Program.RootObject} : RestSharpConsoleApplication.Program.RootObject
locations : {RestSharpConsoleApplication.Program.Locations} : RestSharpConsoleApplication.Program.Locations
__invalid_name__98765 : null : RestSharpConsoleApplication.Program.__invalid_type__98765
num_locations : 1 : int
Obviously I am not creating (json2csharp) the right classes for the DeserializeObject, and sadly I have no control over the JSON response (vendor = SimpliSafe).
It is obvious the "98765" is meant to be a value (location number) but json2csharp makes it into this __invalid_type__98765 class and this is probably why it gets null.
Any idea how should the classes look for this particular JSON to be successfully deserialized?
Thanks!

You should be able to do this with a dictionary:
public class MyData{
[JsonProperty("locations")]
public Dictionary<string, Location> Locations {get;set;}
}
public class Location
{
public string street1 { get; set; }
public string street2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postal_code { get; set; }
public string s_status { get; set; }
public string system_state { get; set; }
}
Do you have a non-Express version of Visual Studio? If so, copy the JSON to clipboard and then go to the Visual Studio menu: Edit >> Paste special >> Paste JSON as classes.
Using that gives:
public class Rootobject {
public int num_locations { get; set; }
public Locations locations { get; set; }
}
public class Locations {
public _98765 _98765 { get; set; }
}
public class _98765 {
public string street1 { get; set; }
public string street2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postal_code { get; set; }
public string s_status { get; set; }
public string system_state { get; set; }
}
That suggests your JSON structure is not quite right.
You can also specify the property name via an attribute to use to get around this:
public class RootObject
{
public int num_locations { get; set; }
public Locations locations { get; set; }
}
public class Locations
{
[JsonProperty("98765")]
public LocationInner Inner { get; set; }
}
public class LocationInner
{
public string street1 { get; set; }
public string street2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postal_code { get; set; }
public string s_status { get; set; }
public string system_state { get; set; }
}
...but it would really be better if the JSON were properly formatted such that the Locations was actually an array of location objects.
