Found an odd issue when trying to deserialize a JSON string into a C# Object. It "seems" to perform the operation successfully (as in it does not throw any exception etc), however the outputted POCO contains does not contain any data from the JSON string, it only contains type default data (nulls,"", 0 etc). I have tried this process with other JSON and it works fine.
private string GetJson()
{

Look like you JSON string is not in correct format that you are trying to deserialize. For example i have not find show property in the C# class but it present in JSON.
So this issue I couldn't figure out in the night or early in the morning - it took me till this afternoon until I realised that I was had the wrong JSON!!, so no wonder it wasn't working! I got mixed up with a few different apis that provided JSON. Thanks to those who had pointed out that the class looks wrong, made me double check my code and realise the simplicity of this issue. Kinda needed some rubber ducking to spot the problem. Cheers

I'm trying to turn the string result below in the first line of code into an object of type "Root.cs". I have "Root.cs" class set up in my Visual Studio 2019 "solution" with proper classes set up to turn the string result into the object.
This line of code works fine to get me the string I need:
var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;
Here's the contents of the string "result":
{"sections":[{"id":"Building_Configuration","name":"Building_Configuration","sections":[{"id":"B uilding_Configuration.Parameters_SP","name":"Building_Configuration.Parameters_SP","sectio ns":[],"variables":[{"id":"Building_Configuration.Parameters_SP.fixtureStrategy_SP","name":"Bui lding_Configuration.Parameters_SP.fixtureStrategy_SP","valueType":"String","distinctValueCou nt":3.0,"allowMultipleAssignments":false,"values":[{"name":"ETA","value":"ETA","properties":[{ "id":"fullyqualifiedname","value":"ETA","type":"String"},{"id":"name","value":"ETA","type":"Stri ng"}],"type":"SingletonValue","assigned":"byDefault","incompatible":false},{"name":"ETD","valu e":"ETD","properties":[{"id":"fullyqualifiedname","value":"ETD","type":"String"},{"id":"name","v alue":"ETD","type":"String"}],"type":"SingletonValue","incompatible":false},{"name":"ETA/ETD", "value":"ETA/ETD","properties":[{"id":"fullyqualifiedname","value":"ETA/ETD","type":"String"},{ "id":"name","value":"ETA/ETD","type":"String"}],"type":"SingletonValue","incompatible":false}],"
Now, I need to create the object of type "Root" (My Model Class) for the purpose of picking and choosing certain values out of it. Shouldn't this line work for that?
Root MyObject = JsonConvert.DeserializeObject<Root>(result);
Here's the definition of Root.cs:

My "result" and my "Root.cs" class are each larger than the 30,000 characters limit here. So, I've had to only post a portion of my string "result" and my "Root.cs" class. I'm trying to simplify this question. Please forgive me while I learn how to use this...
Answer: I was making the newbie mistake of trying to return a string that I picked out of a "Root.cs" Model class as a Root object. I had the return type of the method set to Root instead of string. Upon changing the return type to string, that part of my solution works fine.
It works fine like this:
public string CreateExecPost(FormData person2){
var payload = new StringContent(newPost, Encoding.UTF8, "application/json");
var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;//result is already in JSON
Root MyObject = JsonConvert.DeserializeObject<Root>(result);
//return MyObject.language; //WORKS
return MyObject.language;
}
I'm not sure what is causing this to happen. When debugging, I can step through each line, but when it hits the DeserializeObject line, the program doesn't do anything. I can no longer step over or do anything else with the program. No error messages are being thrown either.
[Command("stats")]
public async Task LookupMonsterStats(CommandContext ctx, string name)
{
string monstersUri = "https://www.dnd5eapi.co/api/monsters/";
var formatted = name.Replace(" ", "-");
string apiResponse = string.Empty;
using (var httpClient = new HttpClient())
{
using (var response = await httpClient.GetAsync(monstersUri + formatted))
{
apiResponse = await response.Content.ReadAsStringAsync();
var monster = JsonConvert.DeserializeObject<Monster>(apiResponse);
}
}
await ctx.Channel.SendMessageAsync(apiResponse).ConfigureAwait(false);

As mentioned in a comment your class definition doesn't seem to match the JSON response, assuming you're using Visual Studio it's probably worth opening Debug / Windows / Exception Settings and make sure "Common Language Runtime Exceptions" is checked. Sometimes I've found stepping over in multi-threaded apps can produce unusual results after an exception.
When I pasted your code into LINQPad I got errors on several members you've defined as List<string> when the underlying type is more complex. What I normally do to avoid those errors is copy the raw json from a browser window to the clipboard and with a CS file open in Visual Studio do an Edit / Paste Special / Paste JSON as classes to automatically create the classes. After doing that I got the following that deserialized the data fine:
async Task Main()
{
await LookupMonsterStats("aboleth");
}
public async Task LookupMonsterStats(string name)
{
string monstersUri = "https://www.dnd5eapi.co/api/monsters/";
var formatted = name.Replace(" ", "-");
string apiResponse = string.Empty;
using (var httpClient = new HttpClient())
{
using (var response = await httpClient.GetAsync(monstersUri + formatted))
{
apiResponse = await response.Content.ReadAsStringAsync();
var monster = JsonConvert.DeserializeObject<Monster>(apiResponse);
monster.Dump();
}
}
}
public class Monster

public string index { get; set; }
public string name { get; set; }

I am trying to get the list of commiters
In beginning I ask GitHub API (v3) to get repositories:
https://api.github.com/users/{userName}/repos
ok, got some list, and I got there repository name, which I want to use to get all commits
https://api.github.com/repos/{userName}/{repoName}/commits
the address is correct, I get some information, but...
I don't know how to create classes, I don't understand this JSON structure
see the example on https://api.github.com/repos/octocat/Hello-World/git/commits/
its something like this:
[0]
{
"sha",
"commit":{
"commiter":{
"name",
"email",
}
}
}
so... the commit class should have commit...?
I have tried something like this:
the Commit class
[DataContract(Name="commits")]
public class Commit
{
[DataMember(Name="sha")]
public string Sha{get;set;}
[DataMember(Name="commiter")]
public Commiter Commiter{get;set;}
}
and the commiter class:
[DataContract(Name="commiter")]
public class Commiter
{
[DataMember(Name="name")]
public string Name{get;set;}
[DataMember(Name="email")]
public string Email {get;set;}
[DataMember(Name="date")]
public string Date{get;set;}
[DataMember(Name="message")]
public string Message{get;set;}
}
but the only result when I ask for commits is the SHA field from Commit class, the committer is always null
can someone help me :)?
For generate my POCO class I always use :
http://json2csharp.com/
It's automatic.
For your API it's :
public class Author
{
public string name { get; set; }
public string email { get; set; }
public DateTime date { get; set; }
}
public class Committer
{
public string name { get; set; }

been a while since I posted here. I'm working on an app and need to fetch statistics for a particular video using JSON (C#, UWP).
I already have the statistics as a JSON string but can't seem to parse them properly using Newtonsoft. The value always comes back null. This is my code:
var url = "https://www.googleapis.com/youtube/v3/videos?id=" + videoId + "&key=" + cl.googleAPIKey + "&part=snippet,contentDetails,statistics,status";
var http = new HttpClient();
var response = await http.GetStringAsync(url);
var statistics = JsonConvert.DeserializeObject<Statistics>(response);
string totalViews = statistics.viewCount;
The classes generated by Json2CSharp are:
public class PageInfo
{
public int totalResults { get; set; }
public int resultsPerPage { get; set; }
}
public class Default
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Medium
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class High
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Standard
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Maxres
{
public string url { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class Thumbnails
{
public Default #default { get; set; }
public Medium medium { get; set; }
public High high { get; set; }
public Standard standard { get; set; }
public Maxres maxres { get; set; }
}
public class Localized
{
public string title { get; set; }
public string description { get; set; }
}
public class Snippet
{
public DateTime publishedAt { get; set; }
public string channelId { get; set; }
public string title { get; set; }

public Thumbnails thumbnails { get; set; }
public string channelTitle { get; set; }

}

public string uploadStatus { get; set; }
public string privacyStatus { get; set; }
public string license { get; set; }
public bool embeddable { get; set; }
public bool publicStatsViewable { get; set; }
}
public class Statistics
{
public string viewCount { get; set; }
public string likeCount { get; set; }
public string dislikeCount { get; set; }
public string favoriteCount { get; set; }
public string commentCount { get; set; }
}
public class Item
{
public string kind { get; set; }
public string etag { get; set; }
public string id { get; set; }
public Snippet snippet { get; set; }
public ContentDetails contentDetails { get; set; }
public Status status { get; set; }
public Statistics statistics { get; set; }
}
public class RootObject
{
public string kind { get; set; }
public string etag { get; set; }
public PageInfo pageInfo { get; set; }
public List<Item> items { get; set; }
}
As I say the value will always come back as null regardless of the video ID.
Does anyone have any ideas?
Thanks
You are deserializing to the wrong class. Json2Csharp generated many classes, but Statistics is way down the tree. You should deserialize the RootObject instead:
var root = JsonConvert.DeserializeObject<RootObject>( response );
And then navigate to the statistics within the resulting class structure like for example:
foreach ( var statistics in root.Items.Select( i => i.Statistics) )
{
//do something
}
I am trying to parse JSON response so I created some classes.
Actually I want Leg and Flight class element value. I am trying to get those element value from RootObject but I don't know how to do this. I googled but I am little bit confuse.
I paste my JSON respose , Classes !!

}
Code :
var obj0 = JsonConvert.DeserializeObject<RootObject>(responsedata);
Here I got only Trip class element . I want the Leg and Flight class element.
If you want to find information for a specific leg, you need to use Linq to traverse the tree. For example, if you just know the leg id, you could do something like this:
var allLegs = obj0.trips.tripOption.SelectMany(to => to.slice.SelectMany(sl => sl.segment.Select(sg => sg.leg)));
var leg = allLegs.FirstOrDefault(l => l.id == "yourId");
The query for retrieving a flight would be similar. You could also filter by tripOption id to get a specific tripOption and then retrieve flights or legs that are associated with it.
