Hello, guys! Could you please help me with retrieving the value of a key, contained in a list?
Here is the script:

    public Hashtable all_containers_hashtable = new Hashtable();

    public List<string> container_list_1 = new List<string>();
    public List<string> container_list_2 = new List<string>();


    // Start is called before the first frame update
    void Start()
    {
        container_list_1.Add("name_1");
        container_list_1.Add("description_1");
        container_list_1.Add("param_1_1");
        container_list_1.Add("param_1_2");
        container_list_1.Add("param_1_3");
        all_containers_hashtable.Add("card_1", container_list_1);

        container_list_2.Add("name_2");
        container_list_2.Add("description_2");
        container_list_2.Add("param_2_1");
        container_list_2.Add("param_2_2");
        container_list_2.Add("param_2_3");
        all_containers_hashtable.Add("card_2", container_list_2);


    }

    // Update is called once per frame
    void Update()
    {

        if (Input.GetKeyDown(KeyCode.Q)) {
            Debug.Log(all_containers_hashtable["container_list_1"]);
//returns the type: List
            Debug.Log(all_containers_hashtable["container_list_1"][1]); 
// D o e s n ' t w o r k (intended, it will return "description_1"), instead it gives error
        }


    }

The hashtable doesn’t have a “container_list_1” key. That is a value corresponding to the “card_1” key. Also, since hashtables can receive values of all types without pre-defining (in contrast to dictionaries), you need to typecast your value to access its elements.

List<string> list = (List<string>) all_containers_hashtable ["card_1"]; // Get list by typecasting
Debug.Log(list[1]); // Access the 2nd element of the list
