ArrayList.GetRange Method

Returns an ArrayList which represents a subset of the elements in the source ArrayList.

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

abstract GetRange : 
        index:int * 
        count:int -> ArrayList  
override GetRange : 
        index:int * 
        count:int -> ArrayList


Type: System.Int32

The zero-based ArrayList index at which the range starts.

Type: System.Int32

The number of elements in the range.

Return Value

Type: System.Collections.ArrayList
An ArrayList which represents a subset of the elements in the source ArrayList.


index is less than zero.


count is less than zero.


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

This method does not create copies of the elements. The new ArrayList is only a view window into the source ArrayList. However, all subsequent changes to the source ArrayList must be done through this view window ArrayList. If changes are made directly to the source ArrayList, the view window ArrayList is invalidated and any operations on it will return an InvalidOperationException.

This method is an O(1) operation.

The following code example shows how to set and get a range of elements in the ArrayList.
