C# | Find the first node in LinkedList<T> containing the specified value

Last Updated : 11 Jul, 2025
LinkedList<T>.Find(T) method is used to find the first node that contains the specified value. Syntax: 
public System.Collections.Generic.LinkedListNode<T> Find (T value);
Here, value is the value to locate in the LinkedList. Return Value: This method returns the first LinkedListNode<T> that contains the specified value, if found, otherwise, null. Below given are some examples to understand the implementation in a better way: Example 1: CSHARP 
// C# code to find the first node
// that contains the specified value
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("A");
        myList.AddLast("B");
        myList.AddLast("C");
        myList.AddLast("D");
        myList.AddLast("E");

        // Finding the first node that
        // contains the specified value
        LinkedListNode<String> temp = myList.Find("B");

        Console.WriteLine(temp.Value);
    }
}
Output: 
B
Example 2: CSHARP 
// C# code to find the first node
// that contains the specified value
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>();

        // Adding nodes in LinkedList
        myList.AddLast(5);
        myList.AddLast(7);
        myList.AddLast(9);
        myList.AddLast(11);
        myList.AddLast(12);

        // Finding the first node that
        // contains the specified value
        LinkedListNode<int> temp = myList.Find(15);

        Console.WriteLine(temp.Value);
    }
}
Runtime Error:
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object
Note:
  • The LinkedList is searched forward starting at First and ending at Last.
  • This method performs a linear search. Therefore, this method is an O(n) operation, where n is Count.
