title: How to parse Nullable<DateTime> from a SqlDataReader
body: <p>The DateTime.TryParse method takes a DateTime as an argument, not a DateTime? ?</p>
  
  <p>Right now I have the following code:</p>
  
  <pre><code>if(!DateTime.TryParse(reader["Placed"].ToString(), out _placed)){
      throw new Exception("Order's placed datetime could not be parsed.");
  }
  </code></pre>
  
  <p>where _placed is of type </p>
  
  <pre><code>Nullable&lt;DateTime&gt; _placed = null;
  </code></pre>
  
  <p>What's a way around that?</p>
