Newtonsoft JsonConverter to replicate the serialization of the JsonObjectAttribute on an IEnumerable

Can someone help me create a Newtonsoft.Json.JsonConverter that will write an IEnumerable the same way one is written if the class has the JsonObjectAttribute?

For example, given this class:

public class MyEnumerable<T> :  IEnumerable<T>
{
    public int TotalCount { get; set; }
    public IEnumerable<T> Values { get; set; }

    public IEnumerator<T> GetEnumerator() => Values.GetEnumerator();
    Enumerator IEnumerable.GetEnumerator() => GetEnumerator();
}

I need the result from this:

var me = new MyEnumerable<string>
{
    TotalCount = 2,
    Values = new List<string>
    {
        "a",
        "b"
    }
}
JsonConvert.SerializeObject(obj, Formatting.Indented);

To look like this:

{
    "TotalCount": 2,
    "Values": [
        "a",
        "b"
    ]
}

Doing the above works fine if the class has the JsonObjectAttribute on it like this:

[JsonObject]
public class MyEnumerable<T> :  IEnumerable<T>
{
    ...
}

However without the JsonOjectAttribute the result will look like this:

[
    "a",
    "b"
]

But I cannot use the attribute since I do not own the class I am trying to serialize in this way, Thus I need to write a converter to do this same thing but I am struggling to figure out how.

I tried googling this but I could not find any similar examples and everyone just seems to suggest using the JsonObject attribute, which I can't and do not want to use.

Any assistance would be appreciated.

Additionally I wish I could use System.Text.Json but it doesn’t seem like it will work either until this issue is resolved: https://github.com/dotnet/runtime/issues/63791

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
