title: Write A DataTable with variable columns into a database table
body: <p>This could have been much easier if I used <code>SqlConnection</code>. But now I have an <code>OleDbConnection</code> and I would like to copy an entire <code>DataTable</code> into a database table. The <code>DataTable</code> can have different columns every time. So I would like only the matching columns to be inserted.</p>
  
  <p>How can I achieve this without iterating through my <code>DataTable</code> columns all the time and building an INSERT query according to that?</p>
