Azure: Why is my blob 0KB when I move it?
I was archiving documents in Blob Storage and found that the target files were always being rendered as 0 KB. I was using the following code: var storageAccount = CloudStorageAccount.Parse("CONNECTIONSTRING"); var blobContainer = storageAccount.CreateCloudBlobClient().GetContainerReference("container"); var blob = blobContainer.GetBlobReference("myfilename") // Get the source as a stream Stream stream = new MemoryStream(); blob.DownloadToStream(stream); var destBlob = blobContainer.GetBlockBlobReference(blob.Name); destBlob.UploadFromStream(stream); blob.Delete(); The code should work, except for the fact that the stream needs to be repointed to the start for the download to work. blob.DownloadToStream(stream); (from above) stream.Position = 0; And now the copy/move works
