title: Send information to another form c#
body: <p>I have an application that uploads files to a server, but when I press upload it freezes until it is done, so I was thinking to make another form pop up that says uploading and does all of the uploading on that form nested of freezing that main form. But to do this I need to be able to send the selected information to that other form.</p>
  
  <p>I have tried using a BackgroundWorker but that doesn't work, the form still freezes.</p>
