Json string deserialization C#

Json string deserialization C# - c#

I have this json
and i want to deserialize it so I can get each object's value for example:
"icon_url": "-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXH5ApeO4YmlhxYQknCRvCo04DEVlxkKgpouLWzKjhzw8zFdC5K092kl5SClMj3PLXFhGpC_Pp8j-3I4IG7i1Hn_UI-Nmj3ItDGe1BoN1mCr1G4xL_vhMS8tcmcn3JhuihwsHvbzQv3309k3tBw8A",
The problem is I can make the class(es) that I need so I can deserialize the json because the json string has nested objects.

I used json2csharp to help me generate classes. After some merging and cleaning up, this is what I got:
public class InventoryItem
{
public string id { get; set; }
public string classid { get; set; }
public string instanceid { get; set; }
public string amount { get; set; }
public int pos { get; set; }
}
public class AppData
{
public string def_index { get; set; }
public int? is_itemset_name { get; set; }
public int? limited { get; set; }
}
public class Description
{
public string type { get; set; }
public string value { get; set; }
public string color { get; set; }
public AppData app_data { get; set; }
}
public class Action
{
public string name { get; set; }
public string link { get; set; }
}
public class Tag
{
public string internal_name { get; set; }
public string name { get; set; }
public string category { get; set; }
public string category_name { get; set; }
public string color { get; set; }
}
public class RgDescription
{
public string appid { get; set; }
public string classid { get; set; }
public string instanceid { get; set; }
public string icon_url { get; set; }
public string icon_url_large { get; set; }
public string icon_drag_url { get; set; }
public string name { get; set; }
public string market_hash_name { get; set; }
public string market_name { get; set; }
public string name_color { get; set; }
public string background_color { get; set; }
public string type { get; set; }
public int tradable { get; set; }
public int marketable { get; set; }
public int commodity { get; set; }
public string market_tradable_restriction { get; set; }
public List<Description> descriptions { get; set; }
public List<Action> actions { get; set; }
public List<Action> market_actions { get; set; }
public List<Tag> tags { get; set; }
}
public class RootObject
{
public bool success { get; set; }
public IDictionary<string, InventoryItem> rgInventory { get; set; }
public List<object> rgCurrency { get; set; }
public IDictionary<string, RgDescription> rgDescriptions { get; set; }
public bool more { get; set; }
public bool more_start { get; set; }
}
These appear to work correctly, you can deserialize and serialize with code like this:
var obj = JsonConvert.DeserializeObject<RootObject>(oldString);
Console.WriteLine(obj.rgDescriptions["310776560_302028390"].icon_url); // e.g.
var newString = JsonConvert.SerializeObject(obj,
new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
// null value handling is optional, the above makes it a little more like the source string

How can I convert a StringContent() type to an object of type <MyModelClass> in C# with Visual Studio 2019

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;
}

App is freezing when trying to deserialize Json string to object

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/";

C# Get Json Response into an Array

C# Json Deserialization fails

I'm trying to make an application that can show local TV guide trough JSON rest api C #, but has some problems with deserialization of my Json response.
i'm only intresest in the array NOW in my json call and i do not own the api service.
I get this error message:
An exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.DLL but was not handled in user code
Additional information: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[TDC_Play_TV_Mobil.superclass2+Now]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'now', line 1, position 7.
My function:
private HttpClient client;
public async Task<List<superclass2.Now>> GetComments()
{
client = new HttpClient();
var response = await client.GetAsync(new Uri("http://api.yousee.tv/rest/tvguide/nowandnext/"));
if (response.IsSuccessStatusCode)
{
string json = await response.Content.ReadAsStringAsync();
System.Diagnostics.Debug.WriteLine(json);

Your JSON isn't a List<superclass2.Now>, it's a superclass2.RootObject. So you need to do something like:
public async Task<List<superclass2.Now>> GetComments()
{
client = new HttpClient();
var response = await client.GetAsync(new Uri("http://api.yousee.tv/rest/tvguide/nowandnext/"));
if (response.IsSuccessStatusCode)
{
string json = await response.Content.ReadAsStringAsync();
System.Diagnostics.Debug.WriteLine(json);
var task = Task.Factory.StartNew(() => JsonConvert.DeserializeObject<superclass2.RootObject>(json));
var value = await task;
System.Diagnostics.Debug.WriteLine("Comments er lavet");
return (value == null ? null : value.now);
}
else
{
throw new Exception("Errorhandling message");
}
}
Agree with Jon Skeet it would be nicer to eliminate the nesting of classes, purely for improved readability. If you need these classes to exist only in a specific scope, it is better to use nested namespaces. They aren't causing your bug, however.

How to parse Json from the RootObject?

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 !!
JSON Response :

Classes :
public class Detail

public Data data { get; set; }
public List<TripOption> tripOption { get; set; }
}
public class RootObject
{
public string kind { get; set; }
public Trips trips { get; set; }
}
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.
