LinkedList<T>.CopyTo Method

Copies the entire LinkedList<T> to a compatible one-dimensional Array, starting at the specified index of the target array.

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

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

Parameters

array
Type: T[]
The one-dimensional Array that is the destination of the elements copied from LinkedList<T>. The Array must have zero-based indexing.
index
Type: System.Int32
The zero-based index in array at which copying begins.

Implements

ICollection<T>.CopyTo(T[], Int32)

ExceptionCondition
ArgumentNullException

array is null.

ArgumentOutOfRangeException

index is less than zero.

ArgumentException

The number of elements in the source LinkedList<T> is greater than the available space from index to the end of the destination array.

This method uses Array.Copy to copy the elements.

The elements are copied to the Array in the same order in which the enumerator iterates through the LinkedList<T>.

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

The following code example and output demonstrate the CopyTo method. The code example creates an array the same size as the linked list, and uses the CopyTo method to copy the values of all the nodes to the string array, beginning at element 0 of the array. The code example then clears the array.

This code and output are part of a larger example provided for the LinkedList<T> class.


// Create an array with the same number of
// elements as the inked list.
string[] sArray = new string[sentence.Count];
sentence.CopyTo(sArray, 0);

foreach (string s in sArray)
{
    Console.WriteLine(s);
}
