Adding a list of delegates to AddListener

Question

Basically I know you can do the following:

 obj.GetComponent<Button>().onClick.AddListener(delegate {Use;});

What I want to do is use an array of delegates to create multiple listeners on buttons.

something like this:

 List myList<Delegates> = new List<Delegates>();
 
 myList.add(Use);
 myList.add(Destroy);
 myList.add(Etc);
 
 foreach(Delegate delegate in myList
 {
             GameObject obj = (GameObject)Instantiate(MyButton, myTransform);
             obj.GetComponent<Button>().onClick.AddListener(delegate);
 }

Is this possible? The end result is a UI with buttons for each method stored this way on an object. So different objects will have different methods stored and generate a different set of buttons for the UI. If it isn't possible, what would be the best way to achieve this?

Got it working. My issue was simply that I wasn't properly using UnityAction ><

Now I have (in UnableObject):

 public List<UnityAction> buttonCommandList = new List<UnityAction>();

 public virtual void CreateUIInterface(Text titleText, GameObject buttonMenu, GameObject toolTipButton, PlayerInteraction playerInteraction)
 {
     Debug.Log("Creating Interface");
     titleText.text = GetName();
     foreach (UnityAction command in buttonCommandList)
     {
         GameObject obj = (GameObject)Instantiate(toolTipButton, buttonMenu.transform);
         obj.transform.localScale = new Vector3(1.0f, 1.0f, 1.0f);
         obj.GetComponent<Button>().onClick.AddListener(command);
         Debug.Log("command: " + command);
         Debug.Log("obj: " + obj.name);
     }
 }

And in my inheriting class:

 public override void CreateUIInterface(Text titleText, GameObject buttonMenu, GameObject toolTipButton, PlayerInteraction playerInteraction)
 {
     buttonCommandList.Add(delegate { this.Use(1); });
     buttonCommandList.Add(this.Destroy);
     buttonCommandList.Add(this.Switch);

     base.CreateUIInterface(titleText, buttonMenu, toolTipButton, playerInteraction);
 }

All good! :) (Just need to clear the list afterwards ^^)
