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( "Beginner" ); 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:
4
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
