Constructing the name of the variable being accessed

Hi, maybe this is far out and not suppported whatsoever or totaly and it's a newb question... you tell me :)

Is there a way to construct thru script the name of a variable being access?

When iterating, for example, I could have (This does not work...):

 for(int i = 0; i < childCount; i++){
    var MyConstructedVariableName = ("myChild" + i).ToString();
    if(myGameObject.GetComponent<myScript>().MyConstructedVariableName != null){
      DoSomething();
    }
 }

Inspires anyone?

Thanks!
