要从LinkedList中删除第一次出现的指定值,代码如下-
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("A"); list.AddLast("E"); list.AddLast("F"); list.AddLast("A"); list.AddLast("H"); list.AddLast("A"); list.AddLast("j"); Console.WriteLine("Count of nodes = " + list.Count); Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)"); LinkedList<string>.Enumerator demoEnum = list.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } list.Remove("A"); Console.WriteLine("Count of nodes = " + list.Count); Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)"); demoEnum = list.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } } }
输出结果
这将产生以下输出-
Count of nodes = 10 Elements in LinkedList... (Enumerator iterating through LinkedList) A B C A E F A H A j Count of nodes = 9 Elements in LinkedList... (Enumerator iterating through LinkedList) B C A E F A H A j
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("One"); list.AddLast("Two"); list.AddLast("Three"); list.AddLast("Three"); list.AddLast("Three"); list.AddLast("Four"); Console.WriteLine("Count of nodes = " + list.Count); Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)"); LinkedList<string>.Enumerator demoEnum = list.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } list.Remove("Three"); Console.WriteLine("Count of nodes = " + list.Count); Console.WriteLine("Elements in LinkedList... (Enumerator iterating through LinkedList)"); demoEnum = list.GetEnumerator(); while (demoEnum.MoveNext()) { string res = demoEnum.Current; Console.WriteLine(res); } } }
输出结果
这将产生以下输出-
Count of nodes = 6 Elements in LinkedList... (Enumerator iterating through LinkedList) One Two Three Three Three Four Count of nodes = 5 Elements in LinkedList... (Enumerator iterating through LinkedList) One Two Three Three Four
