title: Copy PDF File with SaveFileDialog()
body: <p>I need help on making a copy of a PDF ,that I created in a fixed Directory, with SaveFileDialog() so that the user can choose where to save it.
  This is my code.</p>
  
  <pre><code>SaveFileDialog savepdf = new SaveFileDialog();
  if (savepdf.ShowDialog() == DialogResult.OK)
    {
      System.IO.File.Copy(pathmain, newdirectory);
    }
  </code></pre>
  
  <p>"pathmain" is the Path of the PDF file that needs a copy and "newdirectory" is the directory that the user chooses.
  How can I get the directory that the user wants?
  Thanks.</p>
