C# Serialize JSON array without using class

Question

I'm trying to serialize this json structure in c# and was wondering how would I serialize the address array in my structure below without having to use classes

Heres the structure

{
    "Name":"Mark",
    "Addresses":[
      {
        "address":"1234 Main street",
      },
      {
        "address":"1234 Pine Street",
      }],
}

Here's how I serialize using a JsonSerializer and only serializing one address

 string jsonObject = JsonSerializer.Serialize(new
                    {
                        name = "Mark",
                        Addresses = new
                        {
                            address= "1234 Main street"
                        },
                    });

How can I serialize the other address

Addresses = new [] {new { address= "1234 Main street" }, new {.…}}, — Chetan

You need to instantiate a collection type, such as an array:

string jsonObject = JsonSerializer.Serialize(new
{
    name = "Mark",
    Addresses = new[]
    {
        new { address = "1234 Main street" }
    },
});
