List Management. Removing from list and making sure item is not null

Questions & Answers
1

This is the way I have been removing objects from a list and making sure that they are not null:

	public void RemoveFromList(Transform targ){
		List<Transform> tempList = targetList;
		for(int i = 0; i < targetList.Count; i++) {
			if(targ == targetList*){*

_ tempList.Remove(tempList*);_
_ break;_
_ }_
_ }_
_ targetList = new List();_
_ for(int i = 0; i < tempList.Count; i++) {_
_ if(tempList != null){
targetList.Add(tempList);
}
}
}*
My question is: Is this alright to do? How taxing is it to recreate lists on the fly like this? These lists do not contain many objects(yet) and I havent noticed any performance issues. I would like to plan for adding more objects to these lists and multiple calls to this function from different objects, but I am unsure if this is the correct method to do this or if there is a better way.
Thanks_

Seems to me like you can simplify that entire thing to: targetList.Remove(targ);

The Remove function of list removes the first occurrence of the object it finds and re-sizes the list.

You will most likely not see any immediate performance improvements until you have a lot of items in the list though.
