Copy Client-Side Page From One Site To The Other SharePoint Site Using PnP

In this post, I am going to show how to copy a modern page from one site to the other SharePoint site.
 
We can achieve this using PnPOnline and CSOM. This code will copy the modern page into another site collection (destination location) and then, it will also copy all the page contents including web parts and other properties of a modern page to the destination page.
 
A Code sample is provided below, 
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Web;  
  4. using System.Linq;  
  5. using System.Text;  
  6. using System.Threading.Tasks;  
  7. using Microsoft.SharePoint.Client;  
  8. using OfficeDevPnP.Core;  
  9. using OfficeDevPnP.Core.Pages;  
  10. namespace CopyModernPage {

  15.         static string destSiteUrl = string.Empty;  
  16.         static string destUserName = string.Empty;
