Downloading and Saving a File from Windows Azure BLOB Storage

In this post I will show you to download a file from Azure BLOB.

Set the Connection String as below,



Function to download and save file is below,

public void  DownloadFileFromBlob(string fileName, string containerName,string storageConnectionString)

        {
            account = CloudStorageAccount.Parse(RoleEnvironment.

            GetConfigurationSettingValue(storageConnectionString));

            blobClient = account.CreateCloudBlobClient();

            container = blobClient.GetContainerReference(containerName);

            blob = container.GetBlobReference(fileName);

            MemoryStream memStream = new MemoryStream();

            blob.DownloadToStream(memStream);

            Response.ContentType = blob.Properties.ContentType;

            Response.AddHeader("Content-Disposition", "Attachment; filename=" + fileName.ToString());

            Response.AddHeader("Content-Length", blob.Properties.Length.ToString());

            Response.BinaryWrite(memStream.ToArray());           

        }

You need to pass the BLOB name as filename, containerName and connection string to download the file.

Thanks for reading. I hope this post was useful. :)
