Getting list of names of Azure blob files in a container?

If you're using Windows Azure Storage 4.3.0, try this code.

List<string> blobNames = list.OfType<CloudBlockBlob>().Select(b => b.Name).ToList();

Here is one more way to get this done:

CloudStorageAccount backupStorageAccount = CloudStorageAccount.Parse(blobConectionString);

var backupBlobClient = backupStorageAccount.CreateCloudBlobClient();
var backupContainer = backupBlobClient.GetContainerReference(container);

// useFlatBlobListing is true to ensure loading all files in
// virtual blob sub-folders as a plain list
var list = backupContainer.ListBlobs(useFlatBlobListing: true);
var listOfFileNames = new List<string>();

foreach (var blob in blobs) {
  var blobFileName = blob.Uri.Segments.Last();
  listOfFileNames.Add(blobFileName); 
}

return listOfFileNames;

Source: How to load list of Azure blob files recursively?

We can get some additional info like Size, Modified date and Name.

CloudStorageAccount backupStorageAccount = CloudStorageAccount.Parse(YOUR_CON_STRING);

var backupBlobClient = backupStorageAccount.CreateCloudBlobClient();
var backupContainer = backupBlobClient.GetContainerReference("CONTAINER");


var blobs = backupContainer.ListBlobs().OfType<CloudBlockBlob>().ToList();

foreach (var blob in blobs)
{
    string bName = blob.Name;
    long bSize = blob.Properties.Length;
    string bModifiedOn = blob.Properties.LastModified.ToString();        
}

Also you can download a specific file by Name.

 // Download file by Name
 string fileName = "Your_file_name";
 CloudBlockBlob blobFile = backupContainer.GetBlockBlobReference(fileName);
 blobFile.DownloadToFile(@"d:\"+ fileName, System.IO.FileMode.Create);

Full answer with details.

        // Parse the connection string and return a reference to the storage account.
        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("AzureBlobConnectionString"));

        CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

        // Retrieve reference to a previously created container.
        CloudBlobContainer container = blobClient.GetContainerReference("container_name");

        // Retrieve reference to a blob named "test.csv"
        CloudBlockBlob blockBlob = container.GetBlockBlobReference("BlobName.tex");

        //Gets List of Blobs
        var list = container.ListBlobs();
        List<string> blobNames = list.OfType<CloudBlockBlob>().Select(b => b.Name).ToList();

This works with WindowsAzure.Storage 9.3.3.

CloudBlobClient cloudBlobClient = storageAccount.CreateCloudBlobClient();
var cloudBlobContainer = cloudBlobClient.GetContainerReference(containerName);

var blobResultSegment = await cloudBlobContainer.ListBlobsSegmentedAsync(continuationToken);
var blobs = blobResultSegment.Results.Select(i => i.Uri.Segments.Last()).ToList();

Update:

Getting list of names of Azure blob files with Azure.Storage.Blobs v12 - Package

var storageConnectionString = "DefaultEndpointsProtocol=...........=core.windows.net";
var blobServiceClient = new BlobServiceClient(storageConnectionString);

//get container
var container = blobServiceClient.GetBlobContainerClient("container_name");

List<string> blobNames = new List<string>();

//Enumerating the blobs may make multiple requests to the service while fetching all the values
//Blobs are ordered lexicographically by name
//if you want metadata set BlobTraits - BlobTraits.Metadata
var blobs = container.GetBlobsAsync(BlobTraits.None, BlobStates.None);
await foreach (var blob in blobs)
{
    blobNames.Add(blob.Name);
}

There are more option and example you can find it here.

This is the link to the nuget package.

The ListBlobs method doesn't appear to exist anymore. Here is an async verison.

    public static async Task<List<string>> ListBlobNamesAsync(CloudBlobContainer container)
    {
        var blobs = await ListBlobsAsync(container);
        return blobs.Cast<CloudBlockBlob>().Select(b => b.Name).ToList();

        //Alternate version
        //return blobs.Select(b => b.Uri.ToString()).Select(s => s.Substring(s.LastIndexOf('/') + 1)).ToList();
    }

    public static async Task<List<IListBlobItem>> ListBlobsAsync(CloudBlobContainer container)
    {
        BlobContinuationToken continuationToken = null; //start at the beginning
        var results = new List<IListBlobItem>();
        do
        {
            var response = await container.ListBlobsSegmentedAsync(continuationToken);
            continuationToken = response.ContinuationToken;
            results.AddRange(response.Results);
        }

        while (continuationToken != null); //when this is null again, we've reached the end
        return results;
    }

You can access the BlobProperties to get the name:

foreach (object o in list)
{
    BlobProperties bp = o as BlobProperties;
    if (bp != null)
    {
        BlobProperties p = _Container.GetBlobProperties(bp.Name);
        var name = p.Name; // get the name
    }
}

  CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString"));
   CloudFileClient fileClient = storageAccount.CreateCloudFileClient();
    CloudFileShare share = fileClient.GetShareReference(ConfigurationManager.AppSettings["ShareReference"]);
    if (share.Exists())
    {
          CloudFileDirectory rootDir = share.GetRootDirectoryReference();
          CloudFileDirectory sampleDir = rootDir.GetDirectoryReference("paths");
          if (sampleDir.Exists())
          {
                IEnumerable<IListFileItem> fileList = sampleDir.ListFilesAndDirectories();
                 //CloudFile file = sampleDir.GetFileReference(FileName + ext);
                 //return file;
           }
           return null;
      }

From fileList one can get all the files from azure file

We have to use ListBlobsSegmentedAsync() method, Then we can find out the blob by the following code :

public CloudBlockBlob GetLatestBlobByBlobNamePattern(CloudBlobContainer container, string blobNamePattern) 
        {
            var root = container.GetDirectoryReference(string.Empty);
            var blobsList = root.ListBlobsSegmentedAsync(null);
            blobsList.Wait();
            BlobResultSegment segment = blobsList.Result;
            List<IListBlobItem> list = new List<IListBlobItem>();
            list.AddRange(segment.Results);
            while (segment.ContinuationToken != null)
            {
                var blobs = container.ListBlobsSegmentedAsync(segment.ContinuationToken);
                blobs.Wait();
                segment = blobs.Result;
                list.AddRange(segment.Results);
            }
            var blob = list.Where(x => x.Uri.Segments.Last().Contains(blobNamePattern)).FirstOrDefault();
            return (CloudBlockBlob)blob;
        }
