Hello. I have a problem with a list.

Hello. I have a problem with a list.

I have this script:

Spoiler

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class StonePickup: MonoBehaviour
5. {
6. void OnMouseOver()
7.     {
8.             if (Input.GetMouseButtonDown(0))
9.             {
10.                 for(int i = 0; i < InventoryP.Inst.Items.Count; i++)
11.                 {
12.                         if (InventoryP.Inst.Items[i].Name == "Stone"))
13.                         {
14.                             InventoryP.Inst.Items[i].Count +=1;
15.                         }
16.                         if (InventoryP.Inst.Items[i].Name != "Stone")
17.                         {
18.  
19.                             Item ITM = new Item();
20.                             ITM.Name = "Stone";
21.                             ITM.Count += 1;
22.                             ITM.ModelForBarTool = StoneH;
23.                             InventoryP.Inst.Items.Add(ITM);
24.                             Destroy(gameObject);
25.                         }
26.             }
27.         }
28.     }
29.  

When I pickup the item, I want to add the same item if "Stone" item doesn't exist, and if exist, I want to add only to count, but this script doesn't work. How can I search in a list to find and item by name? I tried with 'InventoryP.Inst.Items.Name == "Stone" ' ,but it doesn't work. Sorry for my English and please, help me! I hope you understand!
