How Can I Serialize a List to JSON Using System.Text.Json?

Serialize list to JSON using System.Text.Json

In your scenario, the ObjectInJson attribute contains a serialized object containing nested lists. Currently, you are manually generating a JSON string of a list of these objects. This approach is error-prone and not as efficient as using a dedicated JSON serializer.

.NET provides the System.Text.Json library for efficient and reliable JSON serialization. Use it in your scenario:

<code class="language-csharp">using System.Text.Json;

var aList = new List<MyObjectInJson>
{
    new(1, "1"),
    new(2, "2")
};

var json = JsonSerializer.Serialize(aList);
Console.WriteLine(json);</code>

This code will generate a JSON string representing a list of MyObjectInJson objects. The JSON string will contain nested lists as string arrays.
