Compilation Errors for Database Scripts

I'm trying to make an item database so I followed an online guide however, the scripts outlined in the guide have compilation errors. Any help would be appreciated, I'm a beginner in both Unity and C# so please make the explanations simple. The errors indicated in unity are as follows:


1. item.cs
"There are inconsistent line endings in the 'Assets/Inventory/Scripts/item.cs' script. Some are Mac OS X (UNIX) and some are Windows.
This might lead to incorrect line numbers in stacktraces and compiler errors. Many text editors can fix this using Convert Line Endings menu commands." -I tried converting the line endings but the error remained.

Code (CSharp):

1. using UnityEngine;
2.  
3. [CreateAssetMenu(fileName = "New Item", menuName = "Assets/Item")]
4. public class Item : ScriptableObject
5. {
6.     public string itemID;
7.     public string itemName;
8.     [TextArea]
9.     public string itemDescription;
10.     public int itemCost;
11.     public Sprite itemSprite;
12. }

2. ItemDataBase.cs
"There are inconsistent line endings in the 'Assets/Inventory/Scripts/ItemDataBase.cs' script. Some are Mac OS X (UNIX) and some are Windows.
This might lead to incorrect line numbers in stacktraces and compiler errors. Many text editors can fix this using Convert Line Endings menu commands."

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. [CreateAssetMenu(fileName = "New Item Database" , menuName = "Assets/Databases/Item Database")]
6. public class ItemDatabase : ScriptableObject
7. {
8.     public List<Item> allItems;
9. }

3.DataBase.cs
"Assets\Inventory\Scripts\Database.cs(30,40): error CS0119: 'Database.GetRandomItem()' is a method, which is not valid in the given context"
"Assets\Inventory\Scripts\Database.cs(30,40): error CS0119: 'Database.GetRandomItem()' is a method, which is not valid in the given context

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using System.Linq;
5.  
6. public class Database : MonoBehaviour
7. {
8.     public ItemDatabase items;
9.     private static Database instance;
10.  
11.     private void Awake()
12.     {
13.         if(instance == null)
14.         {
15.             instance = this;
16.             DontDestroyOnLoad(gameObject);
17.         }
18.         else
19.         {
20.             Destroy(gameObject);
21.         }
22.     }
23.  
24.     public static Item GetItemByID(string ID)
25.     {
26.         return instance.items.allItems.FirstOrDefault(i => i.itemID == ID);
27.     }
28.     public static Item GetRandomItem()
29.     {
30.         return instance.items.allItems[GetRandomItem.Range(0, instance.items.allItems.count())];
31.     }
32.  
33.  
34. }

"

 

Inconsistent line endings is just a warning. It's also pretty self explanatory. I won't elaborate further.

I think you meant Random.Range probably instead of GetRandomItem.Range?

Also

count()

is incorrect. It's just a property and it's

Count

, capitalized and no parentheses.

 

Thank you for the help, the comp errors are resolved now.
