问题 After creating a blob container with CreateIfNotExists() , I immediately call SetPermissions() to allow users public access to the blobs in the container, but not to the container itself. Like so: CloudBlobContainer pdfContainer = blobClient.GetContainerReference(ContainerName.PDFs); if (pdfContainer.CreateIfNotExists()) pdfContainer.SetPermissions(new BlobContainerPermissions { PublicAccess = BlobContainerPublicAccessType.Blob }); The container is created successfully, but when I log in to

问题 I need to make a backup to my azure database, I'm trying with this command: "C:\Program Files\Microsoft SQL Server\120\DAC\bin\SqlPackage.exe" /Action:Export /SourceServerName:"tcp:MyDataServer.database.windows.net,1433" /SourceDatabaseName:MyDatabase /SourceUser:MyUser /SourcePassword:MyPass /TargetFile:C:\backups\backup.bacpac but it seems that the format that downloads it is "bacpac" and I need it to be ".bak", I tried to change the extension but says: "The TargetFile argument must refer

问题 I am trying to get a shared access signature for a single blob and then download the blob using the REST api. However, I always get a forbidden 403 error message. Both on storage emulator and the cloud. Here is my code: CloudStorageAccount storageAccount = CloudStorageAccount.Parse("myConnectionStringHere..."); CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient(); CloudBlobContainer container = blobClient.GetContainerReference("containerName"); CloudBlob blob = container

问题 Is their any any to convert from Append Blob to Block Blob . Regards C 回答1: Is their any any to convert from Append Blob to Block Blob . Once the blob has been created, its type cannot be changed, and it can be updated only by using operations appropriate for that blob type, i.e., writing a block or list of blocks to a block blob, appending blocks to a append blob, and writing pages to a page blob.

问题 I am trying to get premium storage account (classic) properties using next method: public ServiceProperties GetStorageAccountProperties(string accountName, string accountKey) { var connectionString = string.Format("DefaultEndpointsProtocol=http;AccountName={0};AccountKey={1};", accountName, accountKey); var account = CloudStorageAccount.Parse(connectionString); CloudBlobClient bloblClient = account.CreateCloudBlobClient(); return bloblClient.GetServiceProperties(); } But, it throws a

问题 I have a situation in which I currently upload a CloudBlockBlob using CloudBlockBlob.UploadFromStreamAsync, and then immediately afterward I set a bunch of user metadata on it. The issue is: I have an Event Grid event which is triggered when the blob is uploaded, but the event handler requires the metadata. Long story short, it's a race condition wherein I have to "hope" that the metadata has been set before my event handler responds to the block blob upload. Is there some way to both upload

问题 How to list ALL directories AND subdirectories in a blob container? This is what I have so far: public List<CloudBlobDirectory> Folders { get; set; } public List<CloudBlobDirectory> GetAllFoldersAndSubFoldersFromBlobStorageContainer() { CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString); CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient(); CloudBlobContainer container = blobClient

问题 I know that CloudBlockBlob.DeleteIfExists() returns true if the blob exists and false when it does not. However I'm curious the know what happens if the blob does exist, but something goes wrong in Azure which causes the file deletion to not occur (I can't find any documentation on that behavior). My concern is that it will return false instead of throwing some kind of exception, so I'll believe the blob is deleted, when it's actually still there. In short, if I get a value of false back,
