LinkedListNode<T>.Next 属性

public:
 property System::Collections::Generic::LinkedListNode<T> ^ Next { System::Collections::Generic::LinkedListNode<T> ^ 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)

属性值

对下一个节点的 LinkedList<T>引用，或者 null 当前节点是最后一个元素 （Last） 的 LinkedList<T>引用。

示例

下面的代码示例创建一个 LinkedListNode<T>，将其添加到 a LinkedList<T>，并在更改时 LinkedList<T> 跟踪其属性的值。

using System;
using System.Collections.Generic;

public class GenericCollection  {

   public static void Main()  {

      // Create a new LinkedListNode of type String and displays its properties.
      LinkedListNode<String> lln = new LinkedListNode<String>( "orange" );
      Console.WriteLine( "After creating the node ...." );
      DisplayProperties( lln );

      // Create a new LinkedList.
      LinkedList<String> ll = new LinkedList<String>();

      // Add the "orange" node and display its properties.
      ll.AddLast( lln );
      Console.WriteLine( "After adding the node to the empty LinkedList ...." );
      DisplayProperties( lln );

      // Add nodes before and after the "orange" node and display the "orange" node's properties.
      ll.AddFirst( "red" );
      ll.AddLast( "yellow" );
      Console.WriteLine( "After adding red and yellow ...." );
      DisplayProperties( lln );
   }

   public static void DisplayProperties( LinkedListNode<String> lln )  {
      if ( lln.List == null )
         Console.WriteLine( "   Node is not linked." );
      else
         Console.WriteLine( "   Node belongs to a linked list with {0} elements.", lln.List.Count );

      if ( lln.Previous == null )
         Console.WriteLine( "   Previous node is null." );
      else
         Console.WriteLine( "   Value of previous node: {0}", lln.Previous.Value );

      Console.WriteLine( "   Value of current node:  {0}", lln.Value );

      if ( lln.Next == null )
         Console.WriteLine( "   Next node is null." );
      else
         Console.WriteLine( "   Value of next node:     {0}", lln.Next.Value );

      Console.WriteLine();
   }
}
