title: How to use the ConfigurationManager.AppSettings
body: <p>I've never used the "appSettings" before. How do you configure this in C# to use with a SqlConnection, this is what I use for the "ConnectionStrings"</p>
  
  <pre><code>SqlConnection con = new SqlConnection();
  con.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
  </code></pre>
  
  <p>And this is what I have for the "appSettings"</p>
  
  <pre><code>SqlConnection con = new SqlConnection();
  con = ConfigurationManager.AppSettings("ConnectionString");
  </code></pre>
  
  <p>but it is not working.</p>
