Dictionary<(Of <(TKey, TValue>)>).ICollection.CopyTo Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Copies the elements of the ICollection<(Of <(T>)>) to an array, starting at the specified array index.
Namespace: System.Collections.Generic
Assembly: mscorlib (in mscorlib.dll)
Syntax
Private Sub CopyTo ( _
array As Array, _
index As Integer _
) Implements ICollection.CopyTo
void ICollection.CopyTo(
Array array,
int index
)
Parameters
- array
Type: System..::.Array
The one-dimensional array that is the destination of the elements copied from ICollection<(Of <(T>)>). The array must have zero-based indexing.
- index
Type: System..::.Int32
The zero-based index in array at which copying begins.
Implements
ICollection..::.CopyTo(Array, Int32)
Exceptions
| Exception | Condition |
|---|---|
| ArgumentNullException | array is nullNothingnullptra null reference (Nothing in Visual Basic). |
| ArgumentOutOfRangeException | index is equal to or greater than the length of array. -or- index is less than 0. |
| ArgumentException | array is multidimensional. -or- array does not have zero-based indexing. -or- The number of elements in the source ICollection<(Of <(T>)>) is greater than the available space from index to the end of the destination array. -or- The type of the source ICollection<(Of <(T>)>) cannot be cast automatically to the type of the destination array. |
Remarks
Each element copied from a Dictionary<(Of <(TKey, TValue>)>) is a KeyValuePair<(Of <(TKey, TValue>)>) structure representing a value and its key.
Note
If the type of the source ICollection cannot be cast automatically to the type of the destination array, the nongeneric implementations of ICollection..::.CopyTo throw an InvalidCastException, whereas the generic implementations throw an ArgumentException.
This method is an O(n) operation, where n is Count.
