LinkedList<T> Constructor (IEnumerable<T>)

Initializes a new instance of the LinkedList<T> class that contains elements copied from the specified IEnumerable and has sufficient capacity to accommodate the number of elements copied.

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

public LinkedList(
	IEnumerable<T> collection
)

Parameters

collection
Type: System.Collections.Generic.IEnumerable<T>
The IEnumerable whose elements are copied to the new LinkedList<T>.

ExceptionCondition
ArgumentNullException

collection is null.

LinkedList<T> accepts null as a valid Value for reference types and allows duplicate values.

If collection has no elements then the new LinkedList<T> is empty, and the First and Last properties contain null.

This constructor is an O(n) operation, where n is the number of elements in collection.

The following code example and output demonstrate the LinkedList<T>(IEnumerable<T>) constructor. The example creates an array of strings, then creates and populates a LinkedList<T> by passing the array of strings to the constructor.

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


// Create the link list.
string[] words =
    { "the", "fox", "jumped", "over", "the", "dog" };
LinkedList<string> sentence = new LinkedList<string>(words);
Display(sentence, "The linked list values:");
Console.WriteLine("sentence.Contains(\"jumped\") = {0}",
    sentence.Contains("jumped"));
