I have another problem with Azure Blob Storage, this time with downloading. I get a list of files without a problem, unfortunately when I want to download it I get a 404 error that the file was not found.
using System.IO;
using System.Linq;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;
namespace BlobStorage
{
class Program
{
static void Main(string[] args)
{
CloudStorageAccount backupStorageAccount = CloudStorageAccount.Parse(
"{connectionString}");
var backupBlobClient = backupStorageAccount.CreateCloudBlobClient();
var backupContainer = backupBlobClient.GetContainerReference("{container-name");
var list = backupContainer.ListBlobs(useFlatBlobListing: true);
foreach (var blob in list)
{
var blobFileName = blob.Uri.Segments.Last();
CloudBlockBlob blockBlob = backupContainer.GetBlockBlobReference(blobFileName);
string destinationPath = string.Format(@"D:\" + blobFileName +".txt");
blockBlob.DownloadToFile(destinationPath, FileMode.OpenOrCreate);
}
}
}
}
Error message:
Microsoft.WindowsAzure.Storage.StorageException: "The remote server returned an error: (404) Not found."
Internal exception WebException: The remote server returned an error: (404) Not found.
And points to the line:
blockBlob.DownloadToFile (destinationPath, FileMode.OpenOrCreate);
A file like this most exists in blob storage. When I enter the blob editions, copy the url to a file, I can download it through the browser without any problem. Unfortunately, I can not download it from the application level due to a 404 error.
Only why does such a file exist?
