ReadWrite Stream for Azure Storage RRS feed

  • Question

  • Does Azure Storage or Azure File provides ReadWrite Stream of a blob, without downloading the blob on a local machine memory or disk. There are some operation on Streams requires Stream with CanRead() and CanWrite() as true e.g. below example on Zip file stored as Azure blob and I would like to update a file inside a zip file.  Here Package.Open() expects an ReadWrite Stream

        using Microsoft.WindowsAzure.Storage;
        using Microsoft.WindowsAzure.Storage.Blob;
        using System.IO.Packaging;
        using Microsoft.WindowsAzure.Storage.File;
        using System.IO.Compression;

    using (Package package = Package.Open(zipFileStream, FileMode.Open, FileAccess.ReadWrite))
                    PackagePart part = package.GetPart(new Uri(relativeFilePath, UriKind.Relative));
                    using (StreamWriter writer = new StreamWriter(part.GetStream()))

  • Blob storage is optimized for storing massive amounts of unstructured data. There was no build in stream of blob to update files in zip.

    I would request you to submit an idea at Feedback.
