C# 程序检查节点是否为 LinkedList

使用 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，检查节点"Amy"是否为 LinkedList。是否在列表中，我们将使用 Contains() 方法，如下所示 −
list.Contains("Amy")
该方法将返回布尔值，即本例中的 True。
让我们看一下完整的代码。
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);
}
// 在末尾添加一个节点
var newNode = list.AddLast("Emma");
// 在上面添加的节点后添加一个新节点
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
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
