LinkedList<T>.First property is used to get the first node of the LinkedList<T>. Syntax:
public System.Collections.Generic.LinkedListNode First { get; }
Return Value: The first LinkedListNode<T> of the LinkedList<T>. Below given are some examples to understand the implementation in a better way: Example 1: CSHARP
// C# code to get the first
// node of 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 first node of the LinkedList
        if (myList.Count > 0)
            Console.WriteLine(myList.First.Value);
        else
            Console.WriteLine("LinkedList is empty");
    }
}
Output:
Geeks
Example 2: CSHARP
// C# code to get the first
// node of 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 first node of the LinkedList
        if (myList.Count > 0)
            Console.WriteLine(myList.First.Value);
        else
            Console.WriteLine("LinkedList is empty");
    }
}
Output:
LinkedList is empty
Note:
  • LinkedList accepts null as a valid Value for reference types and allows duplicate values.
  • If the LinkedList is empty, the First and Last properties contain null.
  • Retrieving the value of this property is an O(1) operation.
