c# 3 errors dealing with arrays

Questions & Answers
1

I’m a bit noobish. I was translating a java script to c# and I’m getting 3 errors dealing with my Contents and newContent arrays. These 3 errors are the exact same for line 23. Can someone please help me?

  1. error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected
  2. error CS1502: The best overloaded method match for `System.Collections.ArrayList.ToArray(System.Type)’ has some invalid arguments
  3. error CS1503: Argument #1' cannot convert object’ expression to type `System.Type’

The script -

using UnityEngine;
using System.Collections;

public class Inventory : MonoBehaviour {
	Transform[] Contents;
	public void AddItem ( Transform Item  ){
		ArrayList newContents = new ArrayList(Contents);
		newContents.Add(Item);
		Contents = newContents.ToArray(Transform);
	}
	public void RemoveItem ( Transform Item  ){
		print("made it here");
		ArrayList newContents = new ArrayList(Contents);
		int index = 0;
		bool shouldend = false;
		foreach(Transform i in newContents){
			if(i==Item){
				newContents.RemoveAt(index);
				shouldend = true;
			}
			index++;
			if(shouldend){
				Contents = newContents.ToArray(Transform);
				return;
			}
		}
	}
}

not sure what you’re trying to do with the remove method, but you could make this much simpler by using List. keep your 2 using statements, but add this:

using System.Collections.Generic;

then:

public class Inventory : MonoBehaviour
{
    private List<Transform> _contents;

    void Awake()
    {
        _contents = new List<Transform>();
    }

    public void AddItem(Transform item)
    {
        _contents.Add(item);
    }

    public void RemoveItem(Transform item)
    {
        var index = _contents.IndexOf(item);
        if (index > -1)    // found?
        {
            _contents.RemoveAt(index);
        }
    }
}
