C# Invalid token 'void' in class, struct, or interface member declaration

I am trying to make a new class that I can use. I keep getting the error above at compile.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Inventory : MonoBehaviour
6. {
7.     public int slot_num;
8.     public int itemid;
9.     public int quantity;
10.     public int[,] slot = new int[0, 0];
11.     List<int[,]> inventory = new List<int[,]>();
12.  
13.     public void Generate_inventory()
14.     {
15.         int j;
16.         for (j = 0; j < slot_num; j++)
17.         {
18.             inventory.Add(slot);
19.             Debug.Log(inventory);
20.         }
21.     }
22. }

I'm trying to set it to an empty object so that I can call it into my player but I'm hitting a wall with this right now. Does anyone know how to fix this?

 

The code you posted looks valid, are you sure the error isn't in another file?

 

I found out that when I changed the c# version the error would change/disappear. I need to use C# 7.0+

 

I had the same problem, I had to desinstall Visual studio completely, and reinstall it using Unity Hub. Now it works flawlessly in any C# version.

 

How I install Visual studio using Unity hub?
