C# |获取 LinkedList 中包含的节点数
原文:https://www . geeksforgeeks . org/c-sharp-get-in-linked list 中包含的节点数/
链接列表<T1T5。Count 属性用于获取 LinkedList < T >中实际包含的节点数。
语法:
public int Count { get; }
返回值:链表中实际包含的节点数。
注意:检索该属性的值是一个 O(1)运算。
下面给出了一些例子，以便更好地理解实现:
例 1:
// C# code to get the number
// of nodes actually contained
// in the LinkedList
using System;
using System.Collections;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Creating a LinkedList of Strings
LinkedList<String> myList = new LinkedList<String>();
// Adding nodes in LinkedList
myList.AddLast("Geeks");
myList.AddLast("for");
myList.AddLast("Data Structures");
myList.AddLast("Noida");
// To get the number of nodes actually
// contained in the LinkedList
if (myList.Count > 0)
Console.WriteLine(myList.Count);
else
Console.WriteLine("LinkedList is empty");
}
}
输出:
4
例 2 :
// C# code to get the number
// of nodes actually contained
// in the LinkedList
using System;
using System.Collections;
using System.Collections.Generic;
class GFG {
// Driver code
public static void Main()
{
// Creating a LinkedList of Integers
LinkedList<int> myList = new LinkedList<int>();
// To get the number of nodes actually
// contained in the LinkedList
if (myList.Count > 0)
Console.WriteLine(myList.Count);
else
Console.WriteLine("LinkedList is empty");
}
}
输出:
LinkedList is empty
