insert node at beginning of circular linked list in c#

Csharp program for insert node at beginning of circular linked list. Here problem description and other solutions.

// Include namespace system
using System;
// Csharp Program 
// Insert node at beginning of circular linked list

// Define class of linked list Node
public class LinkNode
{
	public int data;
	public LinkNode next;
	public LinkNode(int data, LinkNode first)
	{
		this.data = data;
		this.next = first;
	}
}
public class CircularLinkedList
{
	public LinkNode head;
	// Class constructors
	public CircularLinkedList()
	{
		this.head = null;
	}
	// Insert node at begining of circular linked list
	public void insert(int value)
	{
		// Create a node
		var node = new LinkNode(value, this.head);
		if (this.head == null)
		{
			// First node of linked list
			this.head = node;
			node.next = this.head;
		}
		else
		{
			var temp = this.head;
			// Find the last node
			while (temp.next != this.head)
			{
				// Visit to next node
				temp = temp.next;
			}
			// Add node
			temp.next = node;
			// make new head node
			this.head = node;
		}
	}
	// Display node element of circular linked list
	public void display()
	{
		if (this.head == null)
		{
			Console.WriteLine("Empty Linked List");
		}
		else
		{
			Console.WriteLine("  Linked List Element : ");
			// Get first node
			var temp = this.head;
			// iterate linked list
			while (temp != null)
			{
				// Display node
				Console.Write("  " + temp.data);
				// Visit to next node
				temp = temp.next;
				if (temp == this.head)
				{
					// Stop iteration
					return;
				}
			}
		}
	}
	public static void Main(String[] args)
	{
		var task = new CircularLinkedList();
		// Add following linked list nodes
		task.insert(8);
		task.insert(7);
		task.insert(6);
		task.insert(5);
		task.insert(4);
		task.insert(3);
		task.insert(2);
		task.insert(1);
		// Display node
		task.display();
	}
}

Output

  Linked List Element :
  1  2  3  4  5  6  7  8
