title: how to convert 24-hour format TimeSpan to 12-hour format TimeSpan?
body: <p>I have TimeSpan data represented as 24-hour format, such as 14:00:00, I wanna convert it to 12-hour format, 2:00 PM, I googled and found something related in stackoverflow and msdn, but didn't solve this problem, can anyone help me? Thanks in advance.</p>
  
  <p><strong>Update</strong>
  Seems that it's possible to convert 24-hour format TimeSpan to String, but impossible to convert the string to 12-hour format TimeSpan :(</p>
  
  <p>But I still got SO MANY good answers, thanks!</p>
