LinkedListNode<T>.List Propriedade

Definição

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Origem:

LinkedList.cs

Obtém o LinkedList<T> ao qual o LinkedListNode<T> pertence.

public:
 property System::Collections::Generic::LinkedList<T> ^ List { System::Collections::Generic::LinkedList<T> ^ get(); };

public System.Collections.Generic.LinkedList<T>? List { get; }

member this.List : System.Collections.Generic.LinkedList<'T>

Public ReadOnly Property List As LinkedList(Of T)

Valor da propriedade

LinkedList<T>

Uma referência ao LinkedList<T> ao qual o LinkedListNode<T> pertence ou null se o LinkedListNode<T> não estiver vinculado.

Exemplos

O exemplo de código a seguir cria um LinkedListNode<T>, o adiciona a um LinkedList<T>e rastreia os valores de suas propriedades conforme as LinkedList<T> alterações.
