C# | Get the number of nodes contained in LinkedList<T>

LinkedList<T>.Count property is used to get the number of nodes actually contained in the LinkedList<T>.

Syntax:

public int Count { get; }

Return Value: The number of nodes actually contained in the LinkedList.

Note: Retrieving the value of this property is an O(1) operation.

Below given are some examples to understand the implementation in a better way:

Example 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"); 
    } 
} 

Output:

Example 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"); 
    } 
} 

Output :

LinkedList is empty
