  <p>Code: ID is being passed as a paramenter which is the file name in blob.:</p>
  
  <pre><code>            var blobClient = storageAccount.CreateCloudBlobClient();
              var container = blobClient.GetContainerReference("images");
              container.CreateIfNotExists();
              var blockBlob = container.GetBlockBlobReference(id);
              blockBlob.FetchAttributes();
              byte[] downloadedImage = new byte[blockBlob.Properties.Length];
              blockBlob.DownloadToByteArray(downloadedImage, 0);
              var imageBase64 = Convert.ToBase64String(downloadedImage);
  </code></pre>
