title: URI formats are not supported
body: <p>I'm basically making a mass email sender in C# using Microsoft Visual Studio, the idea is that it uses real email accounts via SMTP to send the emails so they are not marked as spam, but I keep getting the error:</p>
  
  <pre><code>URI formats are not supported. 
  </code></pre>
  
  <p>Basically the code below retrieves the list of email accounts from my website but throws the error above.</p>
  
  <pre><code>String[] saUsernames = File.ReadAllLines(@"http://mywebsite.com/test/accounts.txt");
  </code></pre>
  
  <p>I've tried loading the file locally and it works fine so i cant figure out what the issue is, anyone got any ideas as I'm well and truly confused </p>
  
  <p>edit: heres the whole script as something else may be causing the error, ive removed some of the links to my site,etc as its a project in development and i dont want to give away many clues</p>
