title: Find all blobs with prepend in Azure Blob Storage
body: <p>We use Azure's <code>.NET Core</code> SDK for blob storage to get and update static blobs, and I want to be able to find all blobs in a specific directory prepended with a certain string of characters.</p>
  
  <p>I can find individual items using something like:</p>
  
  <pre><code>string fileName = "c999iconFile.png";
  
  var blob = _myDirectory.GetBlobReference(fileName);
  </code></pre>
  
  <p>But I can't seem to be able to find a way to find all <code>blobs</code> prepended with something like <code>c999</code>.</p>
  
  <p>We're looking to find a list of blobs that match a certain prepend and then make a mass delete on them.</p>
  
  <p>The brute force solution is to iterate through one-by-one and do it but that seems wasteful.</p>
  
  <p>Is there a way to achieve this?</p>
