How would I make a ListChangedEvent?

using System;
using System.ComponentModel;

public class InfoManager : MonoBehaviour
{
    private event ListChangedEventHandler ListChanged(object sender, ListChangedEventArgs args)
    {
        //event code
    }
}

So I gave it a shot, but the parentheses give the error, cannot specify constructor arguments in declaration. What did I do wrong? I’m a beginner, and haven’t been able to figure this one out. Thanks in advance!

List doesn’t throw events as far as I know.

However, I did find the following, where someone created something to do what you are looking for…

Take a look at this and see if it helps…
