title: Reading DataSet
body: <p>How do I read data from a DataSet in WPF? I have a train schedule table with just 2 columns and I want to be able to read the departure times and calculate when the next train is leaving. For example, the time now is 12:29 and my application should tell me that next train will depart at 12:33.</p>
  
  <p>I already googled left and right. I'm on .NET 3.5.</p>
