Generic List<> as a property

I have a Type List<string>. How would I call the clear method on the List if it was a property.
This is how my property looks

List<string> _RecieveData = new List<string>();//Data Returned from the clock
        public List<string> RecieveData
        {
            get
            {
                return _RecieveData;
            }
            set
            {
                _RecieveData.Clear();
            }
        }

If you want to use the setter to clear, you could use RecieveData = null; Your set method would then ignore the nulll (because you haven't used value). But I don't know why you would do it like that, that's just confusing.

RecieveData.clear() is more clear.

If I assign another List<string> MyList = RecieveDate;
Then run RecieveData.clear()
The MyList is also Cleared. Due to Reference types.
How do I not clear MyList when clearing RecieveDate ?

Acumentality

They both refer to the same object. If you clear one, you clear both.
You'd have to create another list. If you want to copy the elements from recievedata to that list at the same time, use:

List<String> myList = new List<String>(RecieveData);
