Got the solution:

 public ActionResult ConvertImageToBase64(baseImage img111)
        {
            string base64String = string.Empty;
            // Convert Image to Base64
            using (var img = System.Drawing.Image.FromFile(img111.Image)) // Image Path from File Upload Controller
            {
                using (var memStream = new MemoryStream())
                {
                    img.Save(memStream, img.RawFormat);
                    byte[] imageBytes = memStream.ToArray();

                    // Convert byte[] to Base64 String
                     base64String = Convert.ToBase64String(imageBytes);

                    ViewBag.Image64 = base64String;
                 //   return base64String;
                }
            }

    //        at View side
    //<img src="data:image/jpg;base64,@ViewBag.Image64" width="80" height="80"/>

or

            Base64StringToImage(base64String);
            // Convert Base64 to Image 
  
             

            return View();
        }

        public System.Drawing.Image Base64StringToImage(string base64String)
        {
            byte[] imageBytes = Convert.FromBase64String(base64String);
            var memStream = new MemoryStream(imageBytes, 0, imageBytes.Length);

            memStream.Write(imageBytes, 0, imageBytes.Length);
            var image = System.Drawing.Image.FromStream(memStream);
            return image;
        }
