script with individual function for each gameObject or public script variable to solve inventory system problem

Question

Hi. I am making inventory system where when you pick up item in inventory creates slot with sprite, name, etc. of item (GetComponent<>()). But i want slot to get script with OnUse function, that depends on item that you pick up. And i want all items to has individual OnUse function to be in one Item script, because if i will make scripts with unique function for each item i wouldn't be able to get script components of items that i pick up because it has different names. I could use a bunch of if statement, but it would be very laggy for a lot of items and i would need to write there each item i added.

So i want script with individual function for each item that has it, and that i can edit this function for each item (like public string, float, bool, ... variables).And i want to be able to translate this function to slot script.

Or i want public script variable where i can drop script like public gameObject variable, so this script contains OnUse function. And i want to be able to translate this script variable to slot script.

Or you can suggest your solution for this problem

(All scripts on c#) Maybe I spell something wrong, sorry for bad English.

First of all, using multiple foreach is not laggy, thats a really fast opperation but what you are asking for is basically how to implement child/parents

 public abstract class Parent : MonoBehaviour
 {
     public abstract void OnUse();
 }
 
 public class ChildClassOne : Parent
 {
     public override void OnUse()
     {
         Debug.Log("I am onuse of first class");
     }
 }
 
 public class ChildClassTwo : Parent
 {
     public override void OnUse()
     {
         Debug.Log("I am onuse of second class");
     }
 }

for using it now

 GetComponent<Parent>().OnUse();

and will call the necesary method depending on the class
