Dictionary<TKey,TValue>.Key Collection. ICollection. Copy To(Array, Int32) Method
Copies the elements of the ICollection to an array, starting at a particular array index.
virtual void System.Collections.ICollection.CopyTo(Array ^ array, int index) = System::Collections::ICollection::CopyTo;
void ICollection.CopyTo (Array array, int index);
abstract member System.Collections.ICollection.CopyTo : Array * int -> unit override this.System.Collections.ICollection.CopyTo : Array * int -> unit
Sub CopyTo (array As Array, index As Integer) Implements ICollection.CopyTo
The one-dimensional array that is the destination of the elements copied from the ICollection. The array must have zero-based indexing.
The zero-based index in
array at which copying begins.
index is less than 0.
array is multidimensional.
array does not have zero-based indexing.
The number of elements in the source ICollection is greater than the available space from
index to the end of the destination
The type of the source ICollection cannot be cast automatically to the type of the destination
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.
