Stream blob from Azure storage via razor web app
Working example of responding async to a file request with a blob from Azure Storage. The point is that it doesn't copy the (maybe very large) file to memory.
public async Task<IActionResult> OnPostAsync(string SelectedFileName)
{
var container = new CloudBlobContainer(new Uri(_containerSASUrl));
var blob = container.GetBlobReference(SelectedFileName);
var stream = await blob.OpenReadAsync();
return File(stream, blob.Properties.ContentType, SelectedFileName);
}
