Question by zardini123 · May 26, 2015 at 10:16 PM · 2derrorgameobjectarraylist

2D GameObject Array to 2D List

I have a 2D GameObject array, and I want to convert it into a 2D GameObject List. Using .ToList() gives a error. Is there a way to use something like .ToList() to convert this array, or will I have to craft the list from the array myself?

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using System.Linq;
 
 public class Test : MonoBehaviour {
 
     private GameObject[][] array2D;
     private List<List<GameObject>> list2D = new List<List<GameObject>>();
 
     void Update () {
         array2D = list2D.ToList ();
     }
 }

The error the console gives is:

 Cannot implicitly convert type `System.Collections.Generic.List<UnityEngine.GameObject[]>' to `System.Collections.Generic.List<System.Collections.Generic.List<UnityEngine.GameObject>>'

There is no built in function for C# to convert an array of arrays to a list of lists, which makes sense since the structure is not an array of arrays but rather an array that happens to be filled with arrays.

You are dealing with a two dimensional array and a one dimensional, resizable array (essentially, that is what a list is). I suppose you can create a custom List class to handle such a conversion but as @maccabbe said, this is not possible.
