How do I list blobs contained in a directory Azure

So I am trying to list blobs contained in a virtual folder let's call it "VF"

I have tried many methods for example:

var storageAccount = CloudStorageAccount.Parse("...");

var blobClient = storageAccount.CreateCloudBlobClient();

var container = blobClient.GetContainerReference("Container_Name");

List<IListBlobItem> blobslist = container.ListBlobsSegmentedAsync("VF", true).ToList();

But I receive errors like:

Error: Argument 2: cannot convert from 'bool' to 'Microsoft.WindowsAzure.Storage.Blobl.BlobContinuationToken"}

I am trying to return file contents using an API, is this why I am receiving trouble and am using the incorrect methods?

Any help is greatly appreciated

You need to implement the usage of BlobContinuationToken correctly.

Try it like this

if (CloudStorageAccount.TryParse(connectionString, out CloudStorageAccount storageAccount))
{
    var context = new OperationContext();
    var options = new BlobRequestOptions();
    var cloudBlobClient = storageAccount.CreateCloudBlobClient();
    var cloudBlobContainer = cloudBlobClient.GetContainerReference(blobContainerName);
    BlobContinuationToken blobContinuationToken = null;
    do
    {
        var results = await cloudBlobContainer.ListBlobsSegmentedAsync(null, true, BlobListingDetails.All,
            null, blobContinuationToken, options, context);
        blobContinuationToken = results.ContinuationToken;
        foreach (var item in results.Results)
        {
            //do what you want with each blob
        }
    } while (blobContinuationToken != null);
}
