title: Concatenating string from a list of strings
body: <p>I have a list of strings and I am trying to concatenate it so its one bigger string.</p>
  
  <pre><code>foreach (var item in dir3)
       {
             resultDirectionHtml = string.Join(",",item.html_instructions);
       }
  
  
  await EmailSent(resultDirectionHtml);
  </code></pre>
  
  <p>What happens currently is it sends only the last element of the list.
  How can I make it so it concatenates all 8 or so strings and then sends it ??</p>
