hm, why are you reading it as a string, saving it, then reading the saved file? you already have the body content as a string, you could just use that instead of opening the file for reading

LuxiPewOP•3mo ago

this method don't take this

Pobiega•3mo ago

so don't use DeserializeAsync use Deserialize

LuxiPewOP•3mo ago

okey wait a second

LuxiPewOP•3mo ago

also error

LuxiPewOP•3mo ago

Pobiega•3mo ago

okay, can you show the actual json you get from the API? since you save it to a file, should be easy to export

LuxiPewOP•3mo ago

yes of corse {"location":{"name":"Saint Petersburg","region":"Saint Petersburg City","country":"Russia","lat":59.894,"lon":30.264,"tz_id":"Europe/Moscow","localtime_epoch":1728232583,"localtime":"2024-10-06 19:36"},"current":{"last_updated_epoch":1728232200,"last_updated":"2024-10-06 19:30","temp_c":7.8,"temp_f":46.1,"is_day":0,"condition":{"text":"Clear","icon":"//cdn.weatherapi.com/weather/64x64/night/113.png","code":1000},"wind_mph":5.8,"wind_kph":9.4,"wind_degree":197,"wind_dir":"SSW","pressure_mb":1014.0,"pressure_in":29.94,"precip_mm":0.0,"precip_in":0.0,"humidity":79,"cloud":12,"feelslike_c":6.2,"feelslike_f":43.1,"windchill_c":6.2,"windchill_f":43.1,"heatindex_c":7.8,"heatindex_f":46.1,"dewpoint_c":4.4,"dewpoint_f":39.9,"vis_km":10.0,"vis_miles":6.0,"uv":1.0,"gust_mph":12.2,"gust_kph":19.7}}

Pobiega•3mo ago

is that the whole thing?

LuxiPewOP•3mo ago

yes?

Pobiega•3mo ago

okay so,,, yh note how your structure doesnt match the json at all

Pobiega•3mo ago

this is what the top level object looks like it only has these two props so when you try to deserialize that as your current class, it doesnt match and results in default values everywhere

LuxiPewOP•3mo ago

okey i make a difrent class and send you okey?

Pobiega•3mo ago

public record WeatherResponse(current current);

public record WeatherResponse(current current);

is all you need just take that, deserialize to that and it should work just fine

LuxiPewOP•3mo ago

excuse me please, I didn't quite understand what the problem is. Is it that the class and the structure of the response don't match or something else and I don't quite understand what to do with this line that you wrote...

Pobiega•3mo ago

yeah JSON is structured, meaning its not just flat the json you sent has a root object with two properties: current and location your current class seems to match the current property on that root object, but we cant deserialize to that directly the class you tell the serializer to use must match the structure of the json itself so I made a record that matches the root object

LuxiPewOP•3mo ago

OK, that's what I understood, and what kind of line did you send? this is somthing of class ?

Pobiega•3mo ago

yes a record is a type of class

LuxiPewOP•3mo ago

thx you are a best people in this world a go trying fix my code

Pobiega•3mo ago

удачи! (good luck)

LuxiPewOP•3mo ago

Я удивлен что мне помогли в дискорде .А еще больше я удивлен что вы ответили мне на русском) (I'm surprised that they helped me in Discord. And I'm even more surprised that you answered me in Russian))

Pobiega•3mo ago

My russian is very basic, I mostly know dog commands and things you say to children 😄 but why would you be surprised that you got help? Thats what this discord is for.

LuxiPewOP•3mo ago

Reddit and StackOverflow didn't help me and it seems to me that the discord is smaller at least in terms of the number of people

Pobiega•3mo ago

reddit sucks, so thats why. stack overflow is... hard to explain they are trying to build a repository of unique questions your question is probably not unique

LuxiPewOP•3mo ago

that's why it's surprising to me Well in that case I really shouldn't be surprised at anything and one more question why did you say that you shouldn't use asynchronous Deserialize ?

Pobiega•3mo ago

its async because of streams, ie, reading from a file stream etc because you already had the entire string completely in memory, we can use the sync

LuxiPewOP•3mo ago

that is, because we have already used async to receive a response, we can not use it in deserialization?

LuxiPewOP•3mo ago

to this I should organize the class for deserialization? if yes then how to access variables of nested class?

Pobiega•3mo ago

the other classes dont need to be nested but they can be more important is the properties

LuxiPewOP•3mo ago

can you write an example of such a class, I don’t understand if it’s possible to nest them inside each other and will I then be able to call objects of the class?

Pobiega•3mo ago

yeah sure 1 sec

LuxiPewOP•3mo ago

thx

public class RootObject
{
    public Location Location { get; set; }
    public Current Current { get; set; }
}

public class Current
{
    // ...
}

public class Location
{
    // ...
}

public class RootObject
{
    public Location Location { get; set; }
    public Current Current { get; set; }
}

public class Current
{
    // ...
}

public class Location
{
    // ...
}

this would work or this,

public class RootObject
{
    public Location location { get; set; }
    public Current current { get; set; }
    
    public class Current
    {
        // ...
    }

    public class Location
    {
        // ...
    }
}

public class RootObject
{
    public Location location { get; set; }
    public Current current { get; set; }
    
    public class Current
    {
        // ...
    }

    public class Location
    {
        // ...
    }
}

and you would use it like...

var root = JsonSerializer.Deserialize<RootObject>(responseBody);
Console.WriteLine(root.current.temperature);

var root = JsonSerializer.Deserialize<RootObject>(responseBody);
Console.WriteLine(root.current.temperature);

LuxiPewOP•3mo ago

c; thx i go try

LuxiPewOP•3mo ago

EEEEEEE

LuxiPewOP•3mo ago

I would like to know the name of this line, or rather what it is (array variable or something else that I can google and study)

LuxiPewOP•3mo ago

are these properties?

Pobiega•3mo ago

yes

LuxiPewOP•3mo ago

thx all good all works
