LinkedList < T > .Last属性用于获取LinkedList
句法:
public System.Collections.Generic.LinkedListNode Last { get; }
返回值: LinkedList < T >的最后一个LinkedListNode < T > 。
下面给出了一些示例,以更好地理解实现:
范例1:
// C# code to get the last
// node of the LinkedList
using System;
using System.Collections;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Creating a LinkedList of Strings
LinkedList myList = new LinkedList();
// Adding nodes in LinkedList
myList.AddLast("A");
myList.AddLast("B");
myList.AddLast("C");
myList.AddLast("D");
myList.AddLast("E");
// To get the last node of the LinkedList
if (myList.Count > 0)
Console.WriteLine(myList.Last.Value);
else
Console.WriteLine("LinkedList is empty");
}
}
输出:
E
范例2:
// C# code to get the last
// node of the LinkedList
using System;
using System.Collections;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Creating a LinkedList of Integers
LinkedList myList = new LinkedList();
// To get the last node of the LinkedList
if (myList.Count > 0)
Console.WriteLine(myList.Last.Value);
else
Console.WriteLine("LinkedList is empty");
}
}
输出:
LinkedList is empty
笔记:
- LinkedList接受null作为引用类型的有效值,并允许重复的值。
- 如果LinkedList为空,则First和Last属性包含null 。
- 检索此属性的值是O(1)操作。
