Here is the complete method.

 [HttpPost]
        public ActionResult Index(Doctor doct, HttpPostedFileBase photo)
        {

            try
            {
                if (photo != null && photo.ContentLength > 0)
                {
                    // extract only the fielname
                    var fileName = Path.GetFileName(photo.FileName);
                    doct.Image = fileName.ToString();

                    CloudStorageAccount cloudStorageAccount = DoctorController.GetConnectionString();
                    CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();
                    CloudBlobContainer cloudBlobContainer = cloudBlobClient.GetContainerReference("images");


                    string imageName = Guid.NewGuid().ToString() + "-" +Path.GetExtension(photo.FileName); 

                    CloudBlockBlob BlockBlob = cloudBlobContainer.GetBlockBlobReference(imageName);

                    BlockBlob.Properties.ContentType = photo.ContentType;
                    BlockBlob.UploadFromStreamAsync(photo.InputStream);
                    string imageFullPath = BlockBlob.Uri.ToString();

                    var memoryStream = new MemoryStream();


                    photo.InputStream.CopyTo(memoryStream);
                    memoryStream.ToArray();



                    memoryStream.Seek(0, SeekOrigin.Begin);
                    using (var fs = photo.InputStream)
                    {
                        BlockBlob.UploadFromStreamAsync(memoryStream);
                    }

                }
            }
            catch (Exception ex)
            {

            }


            return View();
        }

where the getconnectionstring method is this.

 static string accountname = ConfigurationManager.AppSettings["accountName"];
      static  string key = ConfigurationManager.AppSettings["key"];


            public static CloudStorageAccount GetConnectionString()
            {

                string connectionString = string.Format("DefaultEndpointsProtocol=https;AccountName={0};AccountKey={1}", accountname, key);
                return CloudStorageAccount.Parse(connectionString);
            }
