title: Join 2 DataTables into 1 in C#
body: <p>I have two identical <code>DataTable</code>s from two different databases (but the ids are unique!).  So now I want to have combine this data into a single <code>DataTable</code>. I have no idea what to do. </p>
  
  <p>I tried the following:</p>
  
  <pre><code>DataTable one = new DataTable();
  one = baza_win.pobierz_dane("SELECT...");
  DataTable two = new DataTable();
  two = baza_win2.pobierz_dane("SELECT...");
  //DataTable sum = one + two;
  DataTable sum = new DataTable();
  sum.Clone(one);
  sum.Merge(two,false);
  </code></pre>
  
  <p>But this doesn't work at <code>sum.Clone(one);</code></p>
  
  <p>Any ideas?</p>
