[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Copies the elements of the dictionary to an array, starting at a particular array index.
Namespace: System.Collections.ObjectModel
Assembly: mscorlib (in mscorlib.dll)
Syntax
Private Sub CopyTo ( _
array As KeyValuePair(Of TKey, TValue)(), _
arrayIndex As Integer _
) Implements ICollection(Of KeyValuePair(Of TKey, TValue)).CopyTo
void ICollection<KeyValuePair<TKey, TValue>>.CopyTo(
KeyValuePair<TKey, TValue>[] array,
int arrayIndex
)
Parameters
- array
Type: array<System.Collections.Generic..::.KeyValuePair<(Of <(TKey, TValue>)>)>[]()[]
The one-dimensional array that is the destination of the elements copied from the dictionary. The array must have zero-based indexing.
- arrayIndex
Type: System..::.Int32
The zero-based index in array at which copying begins.
Implements
ICollection<(Of <(T>)>)..::.CopyTo(array<T>[]()[], Int32)
Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | array is nullNothingnullptra null reference (Nothing in Visual Basic). |
| ArgumentOutOfRangeException | arrayIndex is less than 0. |
| ArgumentException | array is multidimensional. -or- The number of elements in the source dictionary is greater than the available space from arrayIndex to the end of the destination array. -or- Type T cannot be cast automatically to the type of the destination array. |
Remarks
This member is an explicit interface member implementation. It can be used only when the ReadOnlyDictionary<(Of <(TKey, TValue>)>) instance is cast to an ICollection<(Of <(T>)>) interface.
