Getting 404 not found when trying to delete Azure blob

Question

I am getting a list of files hosted in Azure and attempting to delete them.

var blobList = container.ListBlobs(prefix: "/2017/1/", useFlatBlobListing:true);
foreach (var blob in blobList)
{
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(blob.Uri.ToString());
    blockBlob.Delete(); // This line causes a 404 not found exception.
}

When I debug and step through the code the blob.Uri matches the folder structure in Azure so not sure why this exception occurs.

Edit: Found an answer - I have to check the type and box appropriately

foreach (var item in blobList)
{
    if (item.GetType() == typeof(CloudBlockBlob))
    {
        CloudBlockBlob blob = (CloudBlockBlob)item;
        blob.Delete();
    }
}

Echoing what @EJoshuaS stated: don't place your solution in the question. Place it in its own answer. This way, this question can be properly closed out. — David Makogon
