title: attach word document from folder, c# mail message
body: <p>I am trying to attach a word file from one of the folders in the website. 
  This is how I am trying:</p>
  
  <pre><code>Attachment attachment = new Attachment(msg.Attachments.Add(HttpContext.Current.Server.MapPath(@"Docs\" + companyName + ".doc")));
  </code></pre>
  
  <p>I am getting these errors: </p>
  
  <pre><code>The best overloaded method match for 'System.Collections.ObjectModel.Collection&lt;System.Net.Mail.Attachment&gt;.Add(System.Net.Mail.Attachment)' has some invalid arguments 
  cannot convert from 'void' to 'string'  
  cannot convert from 'string' to 'System.Net.Mail.Attachment'
  </code></pre>
  
  <p>Any idea how I can solve this?
  Thanks in advance, Laziale</p>
