Hi i am using cloud blob container here's is my code for downloading
   private void _bgw_downloadfile_DoWork(object sender, DoWorkEventArgs e)
            AddtoLogFile("download file do worker called", "_bgw_downloadfile_DoWork");
            try
                string dwnlocfile = fbd_downloadFileLoc.SelectedPath;
                DataGridViewRow row = dgv_downloadfile.CurrentCell.OwningRow;
                string filenameazure = row.Cells["filename"].Value.ToString();
                string filename = Path.GetFileName(filenameazure);
                string fileext = Path.GetExtension(filenameazure);
                CloudStorageAccount storageAccount = CloudStorageAccount.Parse("DefaultEndpointsProtocol=http;AccountName=" + ACCOUNTNAME + ";AccountKey="
+ ACCOUNTKEY);
                // Create the blob client.
                CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
                // Retrieve reference to a previously created container.
                CloudBlobContainer container = blobClient.GetContainerReference("filetransfer");
                CloudBlockBlob blockBlob = container.GetBlockBlobReference(filenameazure);
                // Save blob contents to a file.
                using (var fileStream = System.IO.File.OpenWrite(dwnlocfile + "\\" + filename))
                    blockBlob.DownloadToStream(fileStream);
            catch (Exception ex)
                AddtoLogFile(ex.ToString(), "_bgw_downloadfile_DoWork");
