Question by artie · Feb 02, 2014 at 08:16 PM · listgenericgetcomponents

How to get a List<> from GetComponents?

GetComponents returns a []. Is there any one-liner way to convert that to a Generic (List or whatever)?

I always forget this, end up landing here, and loose time to search elsewhere, so I leave this for future myself ;)

 List<Collider> collidersToTurnOff = new List<Collider>();
 
 void Awake()
 {
         GetComponentsInChildren(collidersToTurnOff);
 }

With LINQ (requires using System.Linq;):

 var list = GetComponents<SomeComponent>().ToList();

Without LINQ:

 var list = new List<SomeComponent>(GetComponents<SomeComponent>());

Code in C#.

 List<object> list = obj.GetComponents<Thing>().Cast<Object>().ToList();

Should work, otherwise you could write your own function to do it for you.

 for(int i = 0; i < arr.Length; ++i)
 {
  list.Add(arr[i]);
 }
