ArrayList.SetRange Method
Copies the elements of a collection over a range of elements in the ArrayList.

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

Syntax
Visual Basic (Declaration)
Public Overridable Sub SetRange ( _
	index As Integer, _
	c As ICollection _
)
Visual Basic (Usage)
Dim instance As ArrayList
Dim index As Integer
Dim c As ICollection

instance.SetRange(index, c)
C#
public virtual void SetRange (
	int index,
	ICollection c
)
C++
public:
virtual void SetRange (
	int index, 
	ICollection^ c
)
J#
public void SetRange (
	int index, 
	ICollection c
)
JScript
public function SetRange (
	index : int, 
	c : ICollection
)
XAML
Not applicable.

Parameters

index

The zero-based ArrayList index at which to start copying the elements of c.

c

The ICollection whose elements to copy to the ArrayList. The collection itself cannot be a null reference (Nothing in Visual Basic), but it can contain elements that are a null reference (Nothing in Visual Basic).

Exceptions
Exception type Condition

ArgumentOutOfRangeException

index is less than zero.

-or-

index plus the number of elements in c is greater than Count.

ArgumentNullException

c is a null reference (Nothing in Visual Basic).

NotSupportedException

The ArrayList is read-only.

Remarks

ArrayList accepts a null reference (Nothing in Visual Basic) as a valid value and allows duplicate elements.

The order of the elements in the ICollection is preserved in the ArrayList.

This method is an O(n + 1) operation, where n is Count.

Example

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

Visual Basic

Imports System.Collections
