c# - 以编程方式添加和编辑控件

Question

我以编程方式创建一个 WPF TabItem 并将其添加到我的 TabControl。

   var tabItem = new TabItem { Header = "foo" };

现在我想做类似的事情

   var txt1 = new TextBlock { Text = "foo" };
   var txt2 = new TextBlock { Text = "bar" };

   var tabItem = new TabItem { Header = txt1 + txt2 }; // cannot apply operator + to TextBlock and TextBlock
   // Other Idea:
   // var tabItem = new TabItem { Header = new TextBlock { Text = "foo" }.Text + new TextBlock { Name = "txt2", Text = "bar" }};
   // Maybe I could edit my TextBlock via it's name?
   ...
   txt2.Text = "editedBar"; // have to update the header of tabItem.

这有可能吗？我知道在 XAML 中这不是问题。但是现有的架构迫使我尝试这种方式。

我会做这样的事情:

StackPanel panel = new StackPanel();
panel.Children.Add(txt1);
panel.Children.Add(txt2);

var tabItem = new TabItem { Header = panel };
