How to check if multiple files exist in Azure container

Question

I want to check if multiple files exist in Azure container or not. Is there an efficient way to check it other than in foreach loop? Can I do it using LINQ? Is there a better way to do the same?

Answer 1

foreach loop is the most efficient way though. But if the number of blobs is small, you could retrieve a list of all blobs and run the loop on that. 

If you do think performance is a concern, you may consider invoking Exists method simultaneously.
