how do i get a list of all the children of an object

i have a game object , and i want a list off all the children for that model ?

In JS:

  import System.Linq;
  ...

  var allChildren = transform.Cast.<Transform>().Select(function(t) { return t.gameObject; }).ToArray();

In C#

  using System.Linq;
  ...

  var allChildren = transform.Cast<Transform>().Select(t=>t.gameObject).ToArray();

Did you want all of the descendants though?

Transform implements the IEnumerable interface therefore:

// if you want the transform component
Transform[] childsT = new Transform[transform.childCount];
// if you want the underlying GameObject
GameObject[] childsG = new GameObject[transform.childCount];
int i=0;
foreach(Transform child in transform)
{
    childsT *= child;*

childsG = child.gameObject;
i++;
}
Note: this is the same as what Mike suggested but without the use of LINQ. I wonder which one is more efficient though. Internally both use the IEnumerable capabilities, but I think mine is better since is does not require a delegated method. Unless the compiler add the required code on the fly during execution (but this out of the scope of this question).

Transform transforms = gameObject.GetComponentsInChildren();

foreach(Transform trans in transforms)
{
    Debug.Log(tra.name);
}

This will print all the children of this perticular game object.
