title: Datetime format Issue: String was not recognized as a valid DateTime
body: <p>I want to format the input string into <b>MM/dd/yyyy  hh:mm:ss</b> format in C#.<br/>
  The input string is in format <code>MM/dd/yyyy hh:mm:ss</code><br/>
  For example :<code>"04/30/2013 23:00"</code></p>
  
  <p>I tried <code>Convert.ToDateTime()</code> function, but it considers 4 as date and 3 as month which is not what I want. Actually month is 04 and date is 03.</p>
  
  <p>I tried <code>DateTime.ParseExact()</code> function also, But getting Exception.</p>
  
  <p>I am getting error:</p>
