Dictionary<TKey, TValue>.ICollection.CopyTo Method

Copies the elements of the ICollection<T> to an array, starting at the specified array index.

Namespace:  System.Collections.Generic
Assembly:  mscorlib (in mscorlib.dll)

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<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)

ExceptionCondition
ArgumentNullException

array is null.

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<T> is greater than the available space from index to the end of the destination array.

-or-

The type of the source ICollection<T> cannot be cast automatically to the type of the destination array.

Each element copied from a Dictionary<TKey, TValue> is a KeyValuePair<TKey, TValue> structure representing a value and its key.

NoteNote:

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.
