Removes the element at the specified index of the CollectionBase instance. This method is not overridable.
Public Sub RemoveAt ( _ index As Integer _ )
Dim instance As CollectionBase Dim index As Integer instance.RemoveAt(index)
public void RemoveAt( int index )
public: virtual void RemoveAt( int index ) sealed
public final function RemoveAt( index : int )
index is less than zero.
-or-
index is equal to or greater than Count.
In collections of contiguous elements, such as lists, the elements that follow the removed element move up to occupy the vacated spot. If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such as a hash table.
This method is an O(n) operation, where n is Count.
This method calls OnValidate, OnRemove, and OnRemoveComplete.
