How Code works 

The code is a .net core application it extracts the storage account connection string from the environment variables

string conn_str = Environment.GetEnvironmentVariable("AzureWebJobsStorage");

Then list all the tables and delete them 

 var TserviceClient = new TableServiceClient(conn_str);      
 Pageable<TableItem> queryTableResults = TserviceClient.Query();
 foreach (TableItem table in queryTableResults)
     {
        TserviceClient.DeleteTable(table.Name);
        Console.WriteLine($"-Table {table.Name}");
      }

Then list all Queues and delete them 

QueueServiceClient QserviceClient = new QueueServiceClient(conn_str);

//list all queues in the storage account
var myqueues = QserviceClient.GetQueues().AsPages();
//then you can write code to list all the queue names          
 foreach (Azure.Page<QueueItem> queuePage in myqueues)
            {
                foreach (QueueItem q in queuePage.Values)
                {
                    QserviceClient.DeleteQueue(q.Name);
                    //Console.WriteLine($"-Queue {q.Name}" );

                }

            }
