This worked perfect for me on .NET Core 3.1.
To test it:
In Visual Studio 2019, create a winform in .NET Core 3.1. Be sure it has the NuGet package for Newtonsoft.JSON.
Add a button called btnJsonConvTest, and a textbox called txtJSONinput.
Add a new class file to the project - name doesn't matter. Delete standard content from the file.
Select and copy your JSON. In Visual Studio, click Edit > Paste Special > Paste JSON as Classes. This will create the class structure you see below.
Add the bits of code from below. Note that I gave my class the name JSONTestObject.
Run your program, paste your JSON test string into the text box, and click the button.
Code:
using Newtonsoft.Json;
Button click event:
private void btnJsonConvTest_Click(object sender, EventArgs e)
{
JSONTestObject testobj = JsonConvert.DeserializeObject<JSONTestObject>(txtJSONinput.Text);
String res = JsonConvert.SerializeObject(testobj);
MessageBox.Show(res);
}
And the class that VS created for us:
public class JSONTestObject
{
public Data data { get; set; }
}
public class Data
{
public Getreport getReport { get; set; }
}
public class Getreport
{
public string report_date { get; set; }
public string report_date_iso { get; set; }
public Links links { get; set; }
public Results results { get; set; }
public Quota quota { get; set; }
}
public class Links
{
public string __typename { get; set; }
public object proportions_diagram { get; set; }
}
public class Results
{
public string shape_and_cutting_style { get; set; }
public Data1 data { get; set; }
}
public class Data1
{
public Shape shape { get; set; }
public object girdle { get; set; }
public object[] inscription_graphics { get; set; }
}
public class Shape
{
public string shape_category { get; set; }
}
public class Quota
{
public int remaining { get; set; }
}
When I test it, I get the same JSON string back out as went into it, thus proving that both the serialization and deserialization methods correctly move data in and out of the class properties.
