How to convert this JSON to a C# class in .NET Core 3.1?

Question

The json :

{"ipAuthority":1,"data1":[["2020-07-01",1],["2020-07-02",2],["2020-07-03",3],["2020-07-04",4]]}

class root
{
   //??????
}

Then how create the class to format the about json?

You can also [use a dynamic object instead of a fixed class](https://stackoverflow.com/questions/3142495/deserialize-json-into-c-sharp-dynamic-object) if you want to. — CherryDT, Aug 03 '20 at 11:42

@CherryDT I want create a class,then I can return the json like above to the webapi user. — A.K, Aug 03 '20 at 12:33
Wait so your question is the opposite of what you wrote? Not how to convert JSON to a C# class object, but how to write a class that, when serialized, produces given JSON? Maybe you want to edit and clarify your question. — CherryDT, Aug 03 '20 at 12:37
Hille comment resume the way you should ask a question here. But just to give you an hint about what to learn before asking this question again ... [serialization](https://learn.microsoft.com/it-it/dotnet/standard/serialization/system-text-json-how-to) is the key. — weirdgyn, Aug 03 '20 at 13:00

This isn't supported in the framework itself, but many editors have a feature for this included in the box.

Here is an example from Visual studio that will generate your statically typed classes:

Once you have the class, you can use the included in .net core to reverse it back to json, under System.Text.Json. You can read more about it at https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json-how-to

I would like to generate the class manually，I have written one. public class Rootobject { public int IPAuthority { get; set; } public List> Data1 { get; set; } = new List>(); } But It's not correct .The wrong json as follows: {"ipAuthority":1,"data1":[["2020-07-01,1"],["2020-07-02,2"],["2020-07-03,3"],["2020-07-04,4"]]} – A.K Aug 04 '20 at 00:35
