Hi Jesper Petersen,
how I use Storage from azure to upload photos and retrieve images from.
To the Photos files, I suggest you could use Blob Storage to store them.
More details about Azure Storage and choose between these features, see:
https://docs.microsoft.com/en-us/azure/storage/storage-introduction
https://docs.microsoft.com/en-us/azure/storage/storage-decide-blobs-files-disks
If you want to use Azure Blob storage, please refer to the following code:
private async Task<CloudBlockBlob> UploadAndSaveBlobAsync(HttpPostedFileBase imageFile)
{
string blobName = Guid.NewGuid().ToString() + Path.GetExtension(imageFile.FileName);
CloudBlockBlob imageBlob = imagesBlobContainer.GetBlockBlobReference(blobName);
using (var fileStream = imageFile.InputStream)
{
await imageBlob.UploadFromStreamAsync(fileStream);
}
return imageBlob;
}
More details, see:
https://docs.microsoft.com/en-us/azure/storage/storage-dotnet-how-to-use-blobs#upload-a-blob-into-a-container
https://docs.microsoft.com/en-us/azure/cloud-services/cloud-services-dotnet-get-started
If you still want to use File Storage, please refer to the following code:
CloudStorageAccountstorageAccount = CloudStorageAccount.Parse(ConfigurationManager.AppSettings["StorageAccountConnectionString"]);
CloudFileClientfileClient = storageAccount.CreateCloudFileClient();
CloudFileSharefileShare = fileClient.GetShareReference("sharedfiles");
if (fileShare.Exists())
{
string policyName = "DemoPolicy" + new Random().Next(50);
FileSharePermissionsfileSharePermissions = fileShare.GetPermissions();
// define policy
SharedAccessFilePolicysharedAccessFilePolicy = newSharedAccessFilePolicy()
{
SharedAccessExpiryTime = DateTime.UtcNow.AddHours(1),
Permissions = SharedAccessFilePermissions.Read
//Permissions = SharedAccessFilePermissions.Write
};
fileSharePermissions.SharedAccessPolicies.Add(policyName, sharedAccessFilePolicy);
// set permissions of file share
fileShare.SetPermissions(fileSharePermissions);
// generate SAS token based on policy and use to create a new file
CloudFileDirectoryrootDirectory = fileShare.GetRootDirectoryReference();
if (rootDirectory.Exists())
{
CloudFileDirectorycustomDirectory = rootDirectory.GetDirectoryReference("Shared Content");
if (customDirectory.Exists())
{
CloudFile file = customDirectory.GetFileReference("DemoFile.txt");
stringsasToken = file.GetSharedAccessSignature(null, policyName);
//generate URL of file with SAS token
UrifileSASUrl = newUri(file.StorageUri.PrimaryUri.ToString() + sasToken);
CloudFilenewFile = newCloudFile(fileSASUrl);
newFile.UploadText("Hello!");
}
}
}
} catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message);
} finally
{
Console.WriteLine("Enter to exit..");
Console.ReadLine();
}
and:
try
{
CloudStorageAccountstorageAccount = CloudStorageAccount.Parse(ConfigurationManager.AppSettings["StorageAccountConnectionString"]);
CloudFileClientfileClient = storageAccount.CreateCloudFileClient();
CloudFileSharefileShare = fileClient.GetShareReference("sharedfiles");
if (fileShare.Exists())
{
CloudFileDirectoryrootDirectory = fileShare.GetRootDirectoryReference();
if (rootDirectory.Exists())
{
CloudFileDirectorycustomDirectory = rootDirectory.GetDirectoryReference("Shared Content");
if (customDirectory.Exists())
{
CloudFile file = customDirectory.GetFileReference("The Word.docx");
if (file.Exists())
{
Console.WriteLine("Downloading file..");
DownloadFileFromShare(file, @ "D:\Downloaded_The_Word.docx");
}
}
}
}
} catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message);
} finally
{
Console.WriteLine("Enter to exit..");
Console.ReadLine();
}
