this may help you, if you really need to get details count from dynamic object https://stackoverflow.com/questions/4939508/get-value-of-c-sharp-dynamic-property-via-string — Md. Sabbir Ahamed, Apr 16 '21 at 04:58

One way is to map your classes.

public class X {
    public List<Studio> Studios { get; set;}
}

public class Studio {
    public List<Detail> Details { get; set;}
}

public class Detail {
    public string show_name {get; set; }
}

And then:

var json = File.ReadAllText("example2.json");

var x = JsonSerializer.Deserialize<X>(json, new JsonSerializerOptions{ PropertyNameCaseInsensitive = true});

var countOfStudios = x.Studios.Count; // 2

var countOfDetailsFromAllStudios = x.Studios.SelectMany(x => x.Details).Count(); // 3
