Null reference when accessing GameObject in the Array(C#)

Questions & Answers

Hello!
I am new to Unity and I faced a problem with arrays. I create a prefab and try to instantiate it and store instances into my array.
Here’s the code:

public class TestScript : MonoBehaviour
{    
		public Transform somePrefab;
		GameObject[] testArray;

		void Start ()
		{
				testArray = new GameObject[5];
				CreatingObjects ();
				AssignNames ();
		}
	
		void CreatingObjects ()
		{
				for (int i = 0; i < 5; i++) {
						testArray  *= Instantiate (somePrefab) as GameObject;    						*

  •  		}*

  •  }*

  •  void AssignNames ()*

  •  {*

  •  		for (int i = 0; i < 5; i++)*

_ testArray .name = "Cube # " + i;_
* }*
}
Unity gives me NullReferenceException error at line 28 (23 here):

"NullReferenceException: Object reference not set to an instance of an object
TestScript.AssignNames () (at Assets/Scripts/TestScript.cs:28)
TestScript.Start () (at Assets/Scripts/TestScript.cs:14)"
For some reason I cannot access my stored GameObject at specific index.
Unity creates 5 objects but i can’t reach them.
Looks like i don’t know something about Unity arrays but i cannot figure it out.

what if you change:

 public Transform somePrefab;

to:

public Gameobject somePrefab;
