Copies the elements of the ArrayList to a new array of the specified element type.
(in mscorlib.dll)
'Usage
Dim instance As ArrayList
Dim type As Type
Dim returnValue As Array
returnValue = instance.ToArray(type)
'Declaration
Public Overridable Function ToArray ( _
type As Type _
) As Array
Parameters
- type
- Type: System..::.Type
The element Type of the destination array to create and copy elements to.
All of the objects in the ArrayList object will be cast to the Type specified in the type parameter.
