ArrayList.RemoveRange Method (Int32, Int32)

 

Removes a range of elements from the ArrayList.

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

abstract RemoveRange : 
        index:int *
        count:int -> unit
override RemoveRange : 
        index:int *
        count:int -> unit

Parameters

index
Type: System.Int32

The zero-based starting index of the range of elements to remove.

count
Type: System.Int32

The number of elements to remove.

Exception Condition
ArgumentOutOfRangeException

index is less than zero.

-or-

count is less than zero.

ArgumentException

index and count do not denote a valid range of elements in the ArrayList.

NotSupportedException

The ArrayList is read-only.

-or-

The ArrayList has a fixed size.

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.
