Hi,

Here is a complete sample for console app.

namespace Office365.Console  
 {  
     using Microsoft.SharePoint.Client;  
     using Newtonsoft.Json;  
     using System;  
     using System.Collections.Concurrent;  
     using System.IO;  
     using System.Net;  
     using System.Net.Http;  
   
     class Program  
     {  
         private static ConcurrentDictionary<Uri, RESTFormDigest> FormDigests { get; set; }  
   
         static void Main(string[] args)  
         {  
             string username, password;  
		 Console.Write("Enter Username")  
             username = Console.Readline();  
             Console.Write("Enter Password")  
             password = Console.Readline();  
             Uploadfiles(username, password);  
             System.Console.WriteLine("Completed");  
             System.Console.ReadLine();  
         }  
   
         static string siteUrl = "https://sppalsmvp.sharepoint.com/sites/DeveloperSite/";           
   
         public async static void Uploadfiles(string userName, string password)  
         {  
             try  
             {  
                 OfficeDevPnP.Core.AuthenticationManager authMgr = new OfficeDevPnP.Core.AuthenticationManager();  
   
                 using (var ctx = authMgr.GetSharePointOnlineAuthenticatedContextTenant(siteUrl, userName, password))  
                 {  
                     Web web = ctx.Web;  
                     ctx.Load(web);  
                     ctx.Load(web.Lists);  
                     ctx.ExecuteQueryRetry();  
                     List list = web.Lists.GetByTitle("D1");  
                     ctx.Load(list);  
                     ctx.ExecuteQueryRetry();  
                     Folder folder = list.RootFolder.EnsureFolder("Folder1");  
                     ctx.Load(folder);  
                     ctx.ExecuteQueryRetry();  
   
                     Folder folderToUpload = web.GetFolderByServerRelativeUrl(folder.ServerRelativeUrl);  
                     folderToUpload.UploadFile("LargeFile.txt", "D:\LargeFile.txt", true);  
                     folderToUpload.Update();  
                     ctx.Load(folder);  
                     ctx.ExecuteQueryRetry();  
                     folderToUpload.EnsureProperty(f => f.ServerRelativeUrl);  
                     var serverRelativeUrl = folderToUpload.ServerRelativeUrl.TrimEnd('/') + '/' + "LargeFile.txt";  
   
   
   
                 }  
             }  
             catch (Exception ex) {  
                 System.Console.WriteLine("Exception occurred : " + ex.Message);  
                 System.Console.ReadLine();  
             }  
         }  
   
   
           
     }  
 }

Hi @Babu ,
Sample code for your reference:

string userName = "xxx@xxxx.onmicrosoft.com";  
string password = "xxx";  
var securePassword = new SecureString();  
foreach (char c in password)  
{  
    securePassword.AppendChar(c);  
}  
using (var clientContext = new ClientContext("https://xxx.sharepoint.com/sites/test"))  
{  
    clientContext.Credentials = new SharePointOnlineCredentials(userName, securePassword);  
    Web web = clientContext.Web;  
    clientContext.Load(web, a => a.ServerRelativeUrl);  
    clientContext.ExecuteQuery();  
    List documentsList = clientContext.Web.Lists.GetByTitle("Contact");  
  
    var fileCreationInformation = new FileCreationInformation();  
    //Assign to content byte[] i.e. documentStream  
  
    fileCreationInformation.Content = System.IO.File.ReadAllBytes(@"D:\document.pdf");  
    //Allow owerwrite of document  
  
    fileCreationInformation.Overwrite = true;  
    //Upload URL  
  
    fileCreationInformation.Url = "https://testlz.sharepoint.com/sites/jerrydev/" + "Contact/demo" + "/document.pdf";  
  
    Microsoft.SharePoint.Client.File uploadFile = documentsList.RootFolder.Files.Add(fileCreationInformation);  
  
    //Update the metadata for a field having name "DocType"  
    uploadFile.ListItemAllFields["Title"] = "UploadedviaCSOM";  
  
    uploadFile.ListItemAllFields.Update();  
    clientContext.ExecuteQuery();  
  
}  

Please make sure the file path is valid in System.IO.File.ReadAllBytes method and the fileCreateionInformation.Url should be the complete library file url not the relative url.
