How do I get formatted JSON in .NET

Question

Hi guys.. I wanna make my inputData more readable. i have using Formatting.Indented but the output is still displayed in a line.

        Dim inputData As Object = New With {
                .serviceType = "MOTORCYCLE",
                .delivery = New List(Of Object) From {
                        New With {
                            .toContact = New List(Of Object) From {
                                    New With {
                                        .name = "Bruce Barner",
                                        .phone = "+659855365"
                                    }
                            }
                        }
                },
                .pickup = New List(Of Object) From {
                        New With {
                            .name = "Tony Stark",
                            .phone = "+659855235"
                        }
                }
        }

        Dim body As String = (New JavaScriptSerializer()).Serialize(inputData)
        Response.Write(Newtonsoft.Json.Linq.JValue.Parse(body).ToString(Newtonsoft.Json.Formatting.Indented))

How can i make the output like something below:

{
  "Sizes": [
    "Small",
    "Medium",
    "Large"
  ],
  "Price": 3.99,
  "Expiry": "\/Date(1230447600000-0700)\/",
  "Name": "Apple"
}

Use the “Manage NuGet Packages” command for your project, add a reference to modern System.Text.Json package, then try this code:

Dim opt As New JsonSerializerOptions With {.WriteIndented = True}
Dim result As String = JsonSerializer.Serialize(inputData, opt)
Console.WriteLine(result)
