ArrayList.RemoveAt Method

Removes the element at the specified index of the ArrayList.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

abstract RemoveAt : 
        index:int -> unit 
override RemoveAt : 
        index:int -> unit 

Parameters

index
Type: System.Int32
The zero-based index of the element to remove.

Implements

IList.RemoveAt(Int32)

ExceptionCondition
ArgumentOutOfRangeException

index is less than zero.

-or-

index is equal to or greater than Count.

NotSupportedException

The ArrayList is read-only.

-or-

The ArrayList has a fixed size.

After the element is removed, the size of the collection is adjusted and the value of the Count property is decreased by one.

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.

The following code example shows how to remove elements from the ArrayList.
