I am using Azure Development Blob Storage.
Downloading blob works fine, and I can double-click the image loaded into the visual view of the blob container's container and open the image ...
But if you look at this image:
... is something wrong with Uri?
Here is the code I'm using:
public MemoryStream DownloadBlob(int id) { Photo photo = PhotoServices.GetPhotoById(id); var cloudBlobContainer = _blobClient.GetContainerReference(CurrentBlobContainerName); var blob = cloudBlobContainer.GetBlockBlobReference(photo.BlobUrl); var memorystream = new MemoryStream();
This is how I store blobs:
public CloudBlockBlob UploadBlob(Stream fileStream, string fileName) { var blobName = Guid.NewGuid() + fileName; var blockBlob = GetContainer().GetBlockBlobReference(blobName); blockBlob.UploadFromStream(fileStream); return blockBlob; }
This is how I get blob:
public MemoryStream DownloadBlob(int id) { Photo photo = PhotoServices.GetPhotoById(id); var cloudBlobContainer = _blobClient.GetContainerReference(CurrentBlobContainerName); var blob = cloudBlobContainer.GetBlockBlobReference(photo.BlobUrl); var memorystream = new MemoryStream(); memorystream.Position = 0; blob.DownloadToStream(memorystream); return memorystream; }
This is what blob looks like in dev. storage (available for viewing and viewing)
Name : bla-bla-bla.jpg Content Type : application/octet-stream URL : http://127.0.0.1:10000/devstoreaccount1/userid1/bla-bla-bla.jpg
So ... what should I change to get a picture to get a normal URL?
Su ... are there obvious things I'm doing wrong here?
