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:
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
