Removes the element at the specified index of the CollectionBase instance. This method is not overridable.
Namespace:
System.Collections
Assembly:
mscorlib (in mscorlib.dll)
Visual Basic (Declaration)
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
)
Parameters
- index
- Type: System..::.Int32
The zero-based index of the element to remove.
Implements
IList..::.RemoveAt(Int32)
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.
Notes to Implementers: This method calls OnValidate, OnRemove, and OnRemoveComplete.
