Copies the entire collection to a compatible one-dimensional Array, starting at the specified index of the target array.

Namespace: OSIsoft.AF
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

public void CopyTo(
	PISystem[] array,
	int index
)

Public Sub CopyTo ( 
	array As PISystem(),
	index As Integer
)

Dim instance As PISystems
Dim array As PISystem()
Dim index As Integer

instance.CopyTo(array, index)

public:
virtual void CopyTo(
	array<PISystem^>^ array, 
	int index
) sealed

abstract CopyTo : 
        array : PISystem[] * 
        index : int -> unit 
override CopyTo : 
        array : PISystem[] * 
        index : int -> unit

Parameters

array: Type: OSIsoft.AFPISystem
The one-dimensional Array that is the destination of the items copied from the collection. The Array must have zero-based indexing.
index: Type: SystemInt32
The zero-based index in array at which copying begins.

Implements

ICollectionTCopyTo(T, Int32)

Exceptions

Exception	Condition
ArgumentNullException	array is .
ArgumentOutOfRangeException	index is less than zero.
ArgumentException	array is multidimensional, does not have zero-based indexing, the number of elements in the source collection is greater than the available space from index to the end of the destination array, or type T is not assignable to the item type of the destination array.

Remarks

This method uses System.Array.Copy to copy the items.

The elements are copied to the Array in the same order in which the enumerator iterates through the collection.

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