title: How to get week of the month when selecting a date in datetimepicker?
body: <p>I have a <code>datetimepicker</code> control in winform which I am creating in c#.</p>
  
  <p>How would I get the week number of the month when I select a date in <code>datetimepicker</code> control in c#?</p>
  
  <p>That means, If I select the date as <code>09/09/2014</code> then the result should be shown in next <code>textbox</code> control as 2nd week of the month in the winform.     </p>
