Deep count for object properties

Question

I'd like to count the number of properties within an object. I have found several solutions but none really counts the child\nested propertie.

For instance, I have the following JSON object.

{
        "id": "259a36d2-3852-425f-a70c-3f9477753210",
        "name": "foo",
        "type": "na",
        "text": "ABC.pdf",
        "left": 333,
        "top": 130,
        "w": 134,
        "h": 34,
        "customData": {
            "A": "fa6css4ec8-8ffb-55bca4dde06a",
            "name": "SDF.pdf",
            "IsExists": false,
            "PNumber": 1,
        }
    }

When trying the following I'm getting the result of 9, while I'm expecting 12 (which is the count of the entire properties).

JObject sourceJObject = JsonConvert.DeserializeObject<JObject>(json);
var res= sourceJObject.Count;

I'll be happy for assistant.

try this

    var obj=JObject.Parse(json);
    
    var count=0;
    CountProps(obj, ref count); // count=12

public void CountProps(JToken obj, ref int count)
{
    if (obj is JObject)
        foreach (var property in ((JObject)obj).Properties())
        {
            if (property.Value is JValue) count++;
            if (property.Value is JObject) CountProps(property.Value, ref count);
            if (property.Value is JArray) { count++; CountProps(property.Value, ref count); }
        }
    if (obj.GetType().Name == "JArray")
        foreach (var property in ((JArray)obj))
            if (property is JObject || property is JArray) CountProps(property, ref count);
}
