How can I duplicate tabPage in c#?

问题

How can I duplicate a "tabPage" inside of my TabControl?

I tried this:

   //My TabControl: tc
   //My Tab ID: 0
   TabPage newPage = new TabPage();

   foreach (Control control in tc.TabPages[0].Controls)
   {
      newPage.Controls.Add(control);
   }
   tc.TabPages.Add(newPage);

but it doesn't work.

Thanks in advance.

I got it!

For those who has the same kind of problem, Here is what I’ve done:

I had created a UserControl (thanks a lot for @SLaks and @Brian for your tip), copied all objects from my TabControl to my new UserControl and used the follow code to create a dynamic tabs:

for (int x = 0; x < 3; x++)
{
   UserControl1 uc = new UserControl1();
   TabPage tp = new TabPage();
   tp.Controls.Add(uc);
   this.TabControl1.TabPages.Add(tp);
}

As Schabse mentioned in a comment above, I highly recommend that you do this with User Controls.
