在C#中获取LinkedList中包含的节点数
要获取LinkedList中包含的节点数，代码如下-
示例
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);
Console.WriteLine("First Node = "+list.First.Value);
list.Clear();
Console.WriteLine("节点数（已更新） = " + list.Count);
}
}输出结果
这将产生以下输出-
Count of nodes = 10 First Node = A 节点数（已更新） = 0
示例
让我们看另一个例子-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(String[] args) {
LinkedList<String> list1 = new LinkedList<String>();
list1.AddLast("One");
list1.AddLast("Two");
list1.AddLast("Three");
list1.AddLast("Four");
list1.AddLast("Five");
Console.WriteLine("LinkedList1...");
foreach (string res in list1) {
Console.WriteLine(res);
}
LinkedList<String> list2 = new LinkedList<String>();
list2.AddLast("India");
list2.AddLast("US");
list2.AddLast("UK");
list2.AddLast("Canada");
list2.AddLast("Poland");
list2.AddLast("Netherlands");
Console.WriteLine("LinkedList2...");
foreach (string res in list2) {
Console.WriteLine(res);
}
LinkedList<String> list3 = new LinkedList<String>();
Console.WriteLine("LinkedList3 节点数 = "+list3.Count);
list3 = list2;
Console.WriteLine("LinkedList3 节点数 (已更新) = "+list2.Count);
Console.WriteLine("LinkedList3是否等于LinkedList2? = "+list3.Equals(list2));
}
}输出结果
这将产生以下输出-
LinkedList1... One Two Three Four Five LinkedList2... India US UK Canada Poland Netherlands LinkedList3 节点数 = 0 LinkedList3 节点数 (已更新) = 6 LinkedList3是否等于LinkedList2? = True
