测试了你的代码，工作正常。确保用户/密码正确。

class Program
    {

        const string user = "[e-mail]";
        const string password = "password";
        public static void Upload()
        {
            using (ClientContext clientContext = new ClientContext("https://tenant.sharepoint.com/sites/lee"))
            {
                SecureString pass = new SecureString();
                foreach (char ch in password)
                {
                    pass.AppendChar(ch);
                }
                clientContext.Credentials = new SharePointOnlineCredentials(user, pass);
                Web web = clientContext.Web;
                clientContext.Load(web);
                clientContext.ExecuteQuery();

                if (!string.IsNullOrWhiteSpace("a"))
                {
                    CreateFolder(clientContext.Web, "/sites/lee/mydoc2", "childA");
                }

                //using (FileStream fs = new FileStream(file, FileMode.Open))
                //{
                //    Microsoft.SharePoint.Client.File.SaveBinaryDirect
                //        (clientContext, $"{this.uploadPath}{this.subFolderPath}/{fileName}", fs, true);
                //}

                Console.WriteLine("Uploaded File Successfully");
            }
        }

        public static void CreateFolder(Web web, string relativePath, string fullFolderPath)
        {
            if (web == null)
            {
                throw new ArgumentNullException(nameof(web));
            }

            if (string.IsNullOrWhiteSpace(relativePath))
            {
                throw new ArgumentNullException(nameof(relativePath));
            }

            if (string.IsNullOrWhiteSpace(fullFolderPath))
            {
                throw new ArgumentNullException(fullFolderPath);
            }

            Folder relativeFolder = web.GetFolderByServerRelativeUrl(relativePath);
            CreateFolderInternal(web, relativeFolder, fullFolderPath);
        }

        public static Folder CreateFolderInternal(Web web, Folder parentFolder, string fullFolderPath)
        {
            var folderUrls = fullFolderPath.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
            string folderUrl = folderUrls[0];
            var curFolder = parentFolder.Folders.Add(folderUrl);
            //web.Context.Load(curFolder);
            try
            {
                web.Context.ExecuteQuery();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }


            if (folderUrls.Length > 1)
            {
                var folderPath = string.Join("/", folderUrls, 1, folderUrls.Length - 1);
                return CreateFolderInternal(web, curFolder, folderPath);
            }

            return curFolder;
        }

        static void Main(string[] args)
        {
            Upload();
        }
    }
