Gets the next node in the LinkedList<T>.
public:
property System::Collections::Generic::LinkedListNode<T> ^ Next { System::Collections::Generic::LinkedListNode<T> ^ get(); };public System.Collections.Generic.LinkedListNode<T> Next { get; }public System.Collections.Generic.LinkedListNode<T>? Next { get; }member this.Next : System.Collections.Generic.LinkedListNode<'T>Public ReadOnly Property Next As LinkedListNode(Of T)Property Value
A reference to the next node in the LinkedList<T>, or null if the current node is the last element (Last) of the LinkedList<T>.
Examples
The following code example creates a LinkedListNode<T>, adds it to a LinkedList<T>, and tracks the values of its properties as the LinkedList<T> changes.

// Create a new LinkedList.
LinkedList<String^>^ ll = gcnew LinkedList<String^>();
// Add the "orange" node and display its properties.
ll->AddLast( lln );
Console::WriteLine( "After adding the node to the empty LinkedList ...." );

// Add nodes before and after the "orange" node and display the "orange" node's properties.
