According to your comment you are trying to clear several lists. Where are the lists stored?

If they are stored in a collection named lists, you can clear all of them with:

foreach(var list in lists)
{
    list.Clear();
}

I can see no reason why you are not using list.clear();

It is the best way to do it.

Alternative, if you need,

is by removing each and every list element

int iCount=listToBeRemoved.items.count;

    foreach (int i=0;i<iCount;i++)
            {
                listToBeRemoved.Remove(i);
            }

Hope this helps..

Note: I strongly recommend you to use list.Clear()

you can use like this 

list=null;

then all the list will be considered as empty or clear... hope this help you.

You can assign the List to null instead of calling Clear, with similar performance.

But: After assigning to null, you must call the constructor again to avoid getting a NullReferenceException.
