Invoke microsoft own System.Text.Json.JsonSerialize() method to serialize object,without encoding

1.install-package system.text.json;

2.

using System.Text.Json;

using System.IO;

3.

static void SystemTextJsonDemo()
        {
            var obj = new[]
            {
                new
                {
                    Id=1,
                    Name="Fred",
                    Age=10
                },
                new
                {
                    Id=2,
                    Name="Fred2",
                    Age=20
                },
                new
                {
                    Id=3,
                    Name="Fred3",
                    Age=30
                }
            };
            JsonSerializerOptions jso = new JsonSerializerOptions();
            jso.WriteIndented = true;            
            string jsonValue = JsonSerializer.Serialize(obj, typeof(object), jso);
            File.WriteAllText("JsonText2.json", jsonValue);
            Console.WriteLine(jsonValue);
        }

Please pay attention to the indented parts.Such as the JsonConvert.Serialize(obj,Formating.Indented);

When you want to show the original plain text as defined. Replate the encoder with belowing.

jso.Encoder = System.Text.Encodings.Web.JavaScriptEncoder.UnsafeRelaxedJsonEscaping;

The result illustrated the fact.

 As the declaration of below,The UnsafeRelaxedJsonEscaping option.

//
// Summary:
// Gets a built-in JavaScript encoder instance that is less strict about what is
// encoded.
//
// Returns:
// A JavaScript encoder instance.
public static JavaScriptEncoder UnsafeRelaxedJsonEscaping { get; }
