要从LinkedList中删除所有节点,代码如下-
using System; using System.Collections.Generic; public class Demo { public static void Main() { int [] num = {10, 20, 30, 40, 50}; LinkedList<int> list = new LinkedList<int>(num); Console.WriteLine("LinkedList nodes..."); foreach (var n in list) { Console.WriteLine(n); } list.Clear(); Console.WriteLine("LinkedList现在为空!"); foreach (var n in list) { Console.WriteLine(n); } } }
输出结果
这将产生以下输出-
LinkedList nodes... 10 20 30 40 50 LinkedList现在为空!
让我们看另一个例子-
using System; using System.Collections.Generic; public class Demo { public static void Main(){ LinkedList<String> list = new LinkedList<String>(); list.AddLast("A"); list.AddLast("B"); list.AddLast("C"); list.AddLast("D"); list.AddLast("E"); list.AddLast("F"); list.AddLast("G"); list.AddLast("H"); list.AddLast("I"); list.AddLast("J"); Console.WriteLine("Count of nodes = " + list.Count); list.Clear(); Console.WriteLine("Count of nodes (updated) = " + list.Count); } }
输出结果
这将产生以下输出-
Count of nodes = 10 Count of nodes (updated) = 0
