Azure blob storage search using tags c#

Question

I'm trying to search an Azure blob container for images using tags.

Here is my connection string:

<add key="blobConnString" value="DefaultEndpointsProtocol=https;AccountName=XXXX;AccountKey=XXXXXXXXXXXX;EndpointSuffix=core.windows.net"/>

Here is my method:

private void FindFiles()
{
    var foundItems = new List<TaggedBlobItem>();
    var connectionString = ConfigurationManager.AppSettings["blobConnString"];
    var _client = new BlobServiceClient(connectionString);
    var blobs = _client.FindBlobsByTags("@container = 'images' AND 'invID' = '12345'");
    foreach (var blob in blobs)
    {
        foundItems.Add(blob);
    }
}

And this is the error I get:

Error: Azure.RequestFailedException: Value for one of the query parameters specified in the request URI is invalid.
RequestId:7434f0b1-501e-0001-07a5-4ef3e1000000

Answer 1

For those that ever encounter this, the problem was the type of storage account I created on Azure. I had selected to use hierarchical namespacing and that was breaking the whole thing.

Answer 2

Hello @Drew Jackson ,
Below is the right syntax:

static void AzureBlobSearch()
{
try
{
var foundItems = new List<TaggedBlobItem>();
var connectionString = ConfigurationManager.ConnectionStrings["blob"].ConnectionString;
var _client = new BlobServiceClient(connectionString);
var queryString = @"container = 'test' AND ""test"" = 'test'";
var blobs = _client.FindBlobsByTags(queryString);
foreach (var blob in blobs)
{
foundItems.Add(blob);
}
}
catch(Exception ex)
{
Console.WriteLine(ex.ToString());
}
}

Answer 3

Changing the syntax didn't correct the error
