Remember that all of us were beginners once, and I'd guess many of us have, in the initial stages of learning UI development, and such advanced techniques as run-time Control generation, gotten ... confused Smile | :)

And, I think you are quite confused, here. In this loop:
  foreach (TabPage t in tabControl1.TabPages)
{
    TabPage tabPage1 = new TabPage(tb_PlcUrl.Text);
    if (tabControl1.TabPages.ContainsKey(tb_PlcUrl.Text))
    {
        existTabPage = true;
    }
    allChceked++;
}
You created a new TabPage, but you never used it: outside of the loop it is reclaimed by memory management ... effectively, it doesn't exist.

Serialization of WinForm Controls is problematic in terms of basic Types, like Fonts and Colors, and, for some Controls that contain other Controls (ex. DateTimePicker) or elements that are non serializable (ex. TreeView's NodeCollection). It's a shame WinForms did not include a powerful save/restore feature for all built-in Controls from the start.

I think your first goal should be a better understanding of C# and object.Control creation; for that, I suggest getting a really good book and combining study with programming small examples ... in the past the books on WinForms by Jesse Liberty and Chris Sells were most useful to me.

As you approach the task of saving and restoring run-time created Controls, like TabPages, I suggest you carefully consider:

1. basic attributes: text, color, location

1.a. basic state: visible, enabled, focused, selected, etc.

2. the issue of restoring event handlers ... which cannot be saved ... you've attached at run-time.

3. the extent to which the run-time user is constrained in terms of what they can create, how many whatevers they can create, etc.

4. ... of course: the data ... the unique content of each Control in the TabPage

I suggest you edit your post here, and describe the contents of one of your run-time created TabPage: when you want to save the content: what must be saved ?
