C#程序，用于检查节点是否为LinkedList
使用该Contains()方法检查节点是否为LinkedList。
这是我们的LinkedList。
string [] students = {"Beth","Jennifer","Amy","Vera"};
LinkedList<string> list = new LinkedList<string>(students);现在，要检查节点“Amy”是否在列表中，我们将使用Contains()如下所示的方法-
list.Contains("Amy")在这种情况下，该方法将返回一个布尔值，即True。
让我们看完整的代码。
示例
using System;
using System.Collections.Generic;
class Demo {
static void Main() {
string [] students = {"Beth","Jennifer","Amy","Vera"};
LinkedList<string> list = new LinkedList<string>(students);
foreach (var stu in list) {
Console.WriteLine(stu);
}
//在最后添加一个节点
var newNode = list.AddLast("Emma");
//在上面添加的节点之后添加一个新节点
list.AddAfter(newNode, "Matt");
Console.WriteLine("LinkedList after adding new nodes...");
foreach (var stu in list) {
Console.WriteLine(stu);
}
Console.WriteLine("Is Student Amy (node) in the list?: "+list.Contains("Amy"));
Console.WriteLine("Is Student Anne (node) in the list?: "+list.Contains("Anne"));
}
}输出结果
Beth Jennifer Amy Vera LinkedList after adding new nodes... Beth Jennifer Amy Vera Emma Matt Is Student Amy (node) in the list?: True Is Student Anne (node) in the list?: False
