Multi-Arrays help

Hello everybody, i have a doubt, i'm trying to make hook system, and i'm not able to build it...

My theory:

Create a global table>That table have multiple items with events>Each item have functions

What is the problem, i don't know how create a string indexed table for see if it's the correct item, here is my code

I took the idea from gmod about how it handle hooks

 public delegate void _Hook(UnityEngine.Object[] args);
 
 public class hook : MonoBehaviour {
     
     _Hook[,] hookTable;
 
     public void Start()
     {
         hookTable = new _Hook[1,1];
     }
 
     public void Run( string event_name, UnityEngine.Object[] args)
     {
         foreach (var hook in hookTable) {
             hook(args);
         }
     }
 
     public void Add( string event_name,string name,_Hook func,UnityEngine.Object[] args)
     {
         hookTable[event_name][name] = func(args);
     }
 
     public hookObject[] GetHooks()
     {
         return hookTable;
     }
 
     public void Remove(string event_name,string name)
     {
         hookTable[event_name][ name ] = null;
     }
 }

But i have problems with the hookTable because i can't do it multiarray and make it handle methods...So

How can make a table handle methods or index tables with strings

Thanks for see
