And here are my json class objects

public class Option
{
    public string label { get; set; }
    public string value { get; set; }
}

public class FrontendLabel
{
    public string store_id { get; set; }
    public string label { get; set; }
}

public class MyArray
{
    public string attribute_id { get; set; }
    public string attribute_code { get; set; }
    public string frontend_input { get; set; }
    public string entity_type_id { get; set; }
    public bool is_required { get; set; }
    public List<Option> options { get; set; }
    public bool is_user_defined { get; set; }
    public List<FrontendLabel> frontend_labels { get; set; }
    public string backend_type { get; set; }
    public string is_unique { get; set; }
    public List<object> validation_rules { get; set; }
    public string default_frontend_label { get; set; }
    public string backend_model { get; set; }
    public string default_value { get; set; }
    public string source_model { get; set; }
}

public class Root
{
    public List<MyArray> MyArray { get; set; }
}

But i am getting this error

{"Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Magento.Products.AttributeId.Root' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.\r\nTo fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.\r\nPath '', line 1, position 1."}

Plus here is how i am getting the json

public Root GetAttributeSets(string attributeCode)
    {
        try
        {

Answer 1

Because the JavaScript object you have isn't an object, it's an array. So instead of an instance of Root what you have is an instance of List<MyArray>:

JsonConvert.DeserializeObject<List<MyArray>>(response.Content);

To have an instance of Root the JavaScript object would need to be something like:

{"MyArray": [/* your current JSON */]}
