title: There is no implicit conversion between bool and System.DayOfWeek
body: <p>I want to add into a List days if checkboxes are checked so i do the following:</p>
  
  <pre><code>List&lt;DayOfWeek&gt; result = rbDaily.Checked || rbTwoWeeks.Checked 
                ? new List&lt;DayOfWeek&gt;
                { 
                    checkboxMon.Checked ? true : DayOfWeek.Monday, checkboxWed.Checked ? true : DayOfWeek.Wednesday
                }
                : null;
  </code></pre>
  
  <p>somehow it says for those lines:</p>
  
  <pre><code>checkboxMon.Checked ? true : DayOfWeek.Monday
  checkboxWed.Checked ? true : DayOfWeek.Wednesday
  </code></pre>
  
  <p>There is no implicit conversion between bool and System.DayOfWeek. What should i put there additionally to say not add that day if false is returned?</p>
