Error at Toggles onValueChanged()

Question

I have a gameobject with an toggle which I want to execute a function on change:

levelItem.GetComponent<Toggle>().onValueChanged.AddListener(SetSelectedLevel(levelList*.Number));*

public void SetSelectedLevel(int index) {

•  selectedLevel = index;*
  

• }*
  the levelList*.Number is just an int.*
  I am getting this error on the onValueChange:
  > error CS1502: The best overloaded
  > method match for

Answer 1

This is how the syntax should look like:

levelItem.GetComponent<Toggle>().onValueChanged.AddListener(delegate {
				SetSelectedLevel(levelList[currentItem].Number);
			});

notice the delegate { ... } which has been added inside the AddListener().
