title: How to load a file in Azure Function using PowerShell
body: <p>I have a small function that takes an array of US telephone area codes and returns an array of area codes paired to the state they are in.</p>
  
  <p>The "master list" of area codes to states is a long variable in my function. I'd like to put that in a CSV file instead.</p>
  
  <p>I'm a beginner to using Azure Functions but, even when the file is in the root folder, <code>Get-Content .\filename.csv</code> does not work.</p>
