Link list in c#

using System;

//node structure
class Node {
  public int data;
  public Node next;
};

class LinkedList {
  public Node head;
  //constructor to create an empty LinkedList
  public LinkedList(){
    head = null;
  } 

  //display the content of the list
  public void PrintList() {
    Node temp = new Node();
    temp = this.head;
    if(temp != null) {
      Console.Write("The list contains: ");
      while(temp != null) {
        Console.Write(temp.data + " ");
        temp = temp.next;
      }
      Console.WriteLine();
    } else {
      Console.WriteLine("The list is empty.");
    }
  }     
};

// test the code 
class Implementation { 
  static void Main(string[] args) {
    //create an empty LinkedList
    LinkedList MyList = new LinkedList();

    //Add first node.
    Node first = new Node();
    first.data = 10;
    first.next = null; 
    //linking with head node
    MyList.head = first;

    //Add second node.
    Node second = new Node();
    second.data = 20;
    second.next = null; 
    //linking with first node
    first.next = second;

    //Add third node.
    Node third = new Node();
    third.data = 30;
    third.next = null; 
    //linking with second node
    second.next = third;

    //print the content of list
    MyList.PrintList();
